The Aim-TTi CPX200D replaces the best-selling CPX200, many thousands of which are in use across the world.

A wider PowerFlex range extends maximum voltage from 35V to 60V, whilst the maximum current of 10A is now available up to 16V rather than 12V.

Existing CPX200 owners will appreciate the new features of S-Lock, Range Control, Voltage Tracking and Synchronous On/Off. For those requiring bus control, the CPX200DP includes a full set of digital interfaces.

To meet the varying needs of today's engineers, a comprehensive array of interfaces is provided. RS-232, USB, GPIB and LAN (Ethernet) with LXI support are provided as standard. Each of the digital bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage, current and status. The interfaces are at ground potential and are opto-isolated from the output terminals.

The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. Currently GPIB remains the most widely used interface for system applications.An RS-232/RS-423 interface is provided for use with legacy systems. This type of serial interface remains in common usage and is perfectly satisfactory for the control of power supplies because data speed is not an issue.

USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use. A USB driver is provided which supports Windows 2000, XP , Vista and Windows 7.

The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct connection to a single PC. This interface supports LXI and is highly appropriate for system use because of its scalable nature and low cost interconnection.

The LAN interface is compliant with LXI-C. LXI (LAN eXtensions for Instrumentation) is the next-generation, LAN-based modular architecture standard for automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems.

The Aim-TTi CPX400D is a different type of laboratory power supply designed to meet the need for flexibility in the choice of voltage and current. A conventional PSU has a fixed current limit giving a power capability that reduces directly with the output voltage. The Aim-TTi CPX400D Power Flex design enables higher currents to be generated at lower voltages within an overall power limit envelope.Each output can provide considerably higher current than a conventional PSU of the same maximum voltage and power (see power curve). Example voltage and current combinations include 60V/7A, 42V/10A, 28V/15A, and 20V/20A.

As technology has changed, many products have moved from analog controls to digital ones. Although digital controls suit many instruments, they do not necessarily suit a bench power supply. Customer research shows that many users prefer the speed and simplicity of conventional analog controls for setting voltage and current. Digital controls may offer greater precision, but often at the expense of ease-of-use. With this in mind, the CPX400D retains the true analog controls of its predecessor. The main disadvantage of analog controls is stability and security. The settings of analog potentiometers can drift over time. More importantly, the settings can be changed accidentally with potentially serious consequences.

The Aim-TTi CPX400D incorporates S-Lock. One press of the lock button transfers control of voltage and current from the analog controls to internal digital circuitry. This offers not just complete security, but exceptional stability as well with each setting controlled by an instrumentation quality DAC.

The Aim-TTi Twin CPX400DP design enables higher currents to be generated at lower voltages within an overall power limit envelope.Each output can provide considerably higher current than a conventional PSU of the same maximum voltage and power (see power curve). Example voltage and current combinations include 60V/7A, 42V/10A, 28V/15A, and 20V/20A.

The PowerFlex regulation system used on the Aim-TTi Twin CPX400DP combines a high frequency pre regulator with a linear post regulator to give both low noise and good transient response. Each output can operate in constant voltage or constant current mode with automatic crossover and mode indication.

Separate voltage and current meters on each output give a resolution of 10mV and 10mA. The fixed resolution avoids the misinterpretation of readings that can occur with auto ranging 3 or 3½ digit meters where the decimal point position moves as the reading changes. Coarse and fine voltage controls are provided. The current control is logarithmic enabling low current levels to be set accurately. A View Settings button enables limit settings to be checked and adjusted at any time.

Each output incorporates remote sense terminals that can be enabled or disabled at the flick of a switch. Remote sensing is essential for maintaining precise regulation at the load and true metering of the load voltage.

The CPX series is a different type of laboratory power supply designed to meet the need for flexibility in the choice of voltage and current. A conventional PSU has a fixed current limit giving a power capability that reduces directly with the output voltage. The TTi PowerFlex design of the CPX series enables higher currents to be generated at lower voltages within an overall power limit envelope.

Each output can provide considerably higher current than a conventional PSU of the same maximum voltage and power. The two outputs of the CPX400D are completely independent and electrically isolated from each other. With V-Track selected, the two outputs remain electrically isolated, but the voltage control of the Master output sets an identical voltage on the Slave output.

This enables the user to create two rails of either polarity and to reference them to different grounds if necessary (e.g. digital ground and analog ground). Alternatively the outputs can be wired in series or parallel to create a voltage capability up to 120V or a current capability up to 40A with the voltage set using a single control.

The Aim-TTi EL302RT has been developed from the top selling EL series. By adding four digit meters and switchable remote sensing, the Thurlby Thandar EL302RT offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer.

The Aim-TTi EL302RT uses true linear regulation for the best possible performance. Excellent line and load regulation is matched by very low output noise and good transient response.

It also incorporates separate voltage and current meters on each main output with a resolution of 10mV and 1mA. The fixed resolution avoids the misinterpretation of readings that can occur with auto-ranging 3 or 3½ digit meters where the decimal point position moves as the reading changes.

Each main output of the Thurlby Thandear EL302RT has a DC on-off switch. This enables voltage and current settings to be viewed before the load is connected and allows multiple outputs to be controlled individually. Surprisingly, many power supplies omit this essential feature.The Aim-TTi EL302RT uses classic analog controls for voltage and current. The large and bright displays have a fixed resolution to avoid confusion. Preset voltage and current levels are shown when the DC output switch is turned off. Remote sense is available when needed but is disabled by setting the switch to local.

Over the years, the PL series has been steadily revised and extended. Hundreds of thousands of PL series units are currently in use across the world and it remains the laboratory power supply of choice for many organisations.

The Aim-TTi Single PL155 achieves an exceptional power density for a linear regulated power supply by offering up to 90W from a ¼ rack 3U sized casing.

This gives it an unusually small bench footprint taking up less space on a crowded bench. For rack-mount application, up to four units can be mounted into a single slot. Despite its small size and linear regulation, the Aim-TTi Single PL155 generates relatively little heat through the use of an advanced phase controlled pre-regulator.

This gives it significantly higher energy efficiency than conventional linear regulated designs, particularly when supplying lower voltages.The internal heat-sinks use fan-assisted convection cooling in order to remove the heat with minimal fan noise.

The Aim-TTi PL155-P offers remote control and read-back using analog, RS232, USB, LAN (LXI) interfaces. They retain all of the capabilities of the New PL Series when under manual control.

When working with any particular piece of equipment, engineers often require a voltage source variable over only a narrow range. Set the voltage too high and damage might occur, set it too low and the circuit may reset.

That’s where the V-Span function of the New PL series comes in. It allows the user to redefine the end-stop values of the voltage control to define a specific voltage range.

An engineer is working on a circuit that will eventually operate from four NiMh cells. They use V-Span to set a Vmax of 5.8V (to prevent over-voltage damage) and a Vmin of 3.6V (to ensure that the circuit doesn’t reset). They now have a power supply which provides high resolution analog control over the exact voltage range they need.

The technology leader Aim-TTi is one of the world’s major producers of laboratory power supplies (PSUs). Aim-TTi has been a major technology innovator in PSUs since 1979 and now offers products ranging from 15W up to 1200W. Hundreds of thousands of Aim-TTi power supplies are in everyday use around the world.

The Aim-TTi PLH120 is a development of the best-selling New PL series of laboratory bench power supplies which is available in 15V, 30V and 60V variants (covered in a separate brochure and on our web site). The Thurlby Thandar Single PLH120 retains the ultra compact format, high power density, and smart analog controls of the PL series but offers voltages up to 250V to cover applications beyond the capabilities of standard bench PSUs and into areas such as magnetics. The Aim-TTi Single PLH120 has been at the forefront of laboratory power supply design for around thirty years during which it has re-defined the state-of-the-art for switch mode products with its innovative Mixed-mode and Power Flex regulator designs.

Demand for linear regulated PSUs has remained strong and continuing development of linear models has generated the lower cost ELR series, and the advanced QL series in addition to the ever popular PL series.

• Linear regulation provides ultra-low noise
• Highly compact (¼ rack 3U) with small bench footprint
• True analog controls with advanced digital features
• Settings can be locked at the touch of a button
• 4 digit voltage and current meters on each output
• Low current range with 0.1mA resolution
• Constant voltage or constant current operation
• Independent, tracking or true parallel modes (PL303QMD)

The Aim-TTi PLH120-P retains the ultra compact format, high power density, and smart analog controls of the PLH120-P, but offers voltages up to 120V to cover applications beyond the capabilities of standard bench PSUs and into areas such as magnetics.

As technology has changed, many products have moved from analog controls to digital ones. Although digital controls suit many instruments, they do not necessarily suit a bench power supply. Customer research shows that many users prefer the speed and simplicity of conventional analog controls for setting voltage and current. Digital controls may offer greater precision, but often at the expense of ease of use. With this in mind, the Aim-TTi PLH120-P has retained the true analog controls of its best selling sister products, the PL series.

The main disadvantage of analog controls is stability and security. The settings of analog potentiometers can drift over time. More importantly, the settings can be changed accidentally with potentially serious consequences. The Aim-TTi PLH120-P incorporates S-Lock. One press of the Lock button transfers control of voltage and current from the analog controls to internal digital circuitry. This offers not just complete security, but exceptional stability as well with each setting controlled by an instrumentation quality DAC.

The Aim-TTi Single QL355 SII offers an unparalleled level of precision. Voltage and current are controlled using instrumentation quality 16-bit DACs enabling voltages to be set to 1mV resolution even at full output voltage. Indeed, the accuracy is sufficient for the QL to be used as a calibration source for some hand-held DMMs.

The Aim-TTi Single QL355 SII provides multiple ranges for increased current capability at lower voltages. The QL355 SII uses pure linear technology and offers unrivalled performance in terms of regulation, output noise and dynamics. Line and load regulation are close to the limit of measurement. Recovery time from transient current pulses is better than 50μs.

Of equal importance for critical applications in areas such as telecoms is common mode noise current (the noise current flowing between the output terminals and ground). This is less than 4μA rms on the QL355 SII dramatically better than most other PSUs.

• Single output or triple output models
• Setting by direct numeric entry or spin wheel
• 1mV resolution at up to 56V
• Multiple ranges for increased current flexibility
• Multiple non-volatile setting memories
• OVP and OCP trips with alarm output

The Aim-TTi QL355P SII offers an unparalleled level of precision. Voltage and current are controlled using instrumentation quality 16-bit DACs enabling voltages to be set to 1mV resolution even at full output voltage.

Indeed, the accuracy is sufficient for the QL to be used as a calibration source for some hand-held DMMs. The QL series uses pure linear technology and offers unrivalled performance in terms of regulation, output noise and dynamics. Line and load regulation are close to the limit of measurement. Recovery time from transient current pulses is better than 50μs. Differential output noise is less than 350μV rms in CV mode and down to 20μA rms in CI mode.

Of equal importance for critical applications in areas such as telecoms is common mode noise current (the noise current flowing between the output terminals and ground). This is less than 4μA rms on the QL Series - dramatically better than most other PSUs.

The user interface of the QL series has been painstakingly designed to provide rapid control whilst guarding against any possibility of error. Unlike other digitally controlled units, the QL series provides both numeric and rotary control. Illuminated keys and display legends provide instant confirmation of settings and status.

For those preferring quasi-analogue control, or for applications where the voltage or current must be gradually changed, the Jog wheel is available. The wheel has a positive stepped action but can be spun rapidly when required. Output voltage can be incremented or decremented in steps of 0.1V, 10mV or 1mV. Current steps can be selected from 0.1A down to 0.1mA. The Jog function can be left permanently engaged or can be disabled at the touch of a button.
