Lo-Volt Power Supply

 Lo-Volt Power Supply

This lo-volt power supply unit provides voltages of 2, 4, 6, 9, 12 or 14V AC or unsmoothed DC at 4A continuously, or up to 5A for periods of 1 hour. Voltages are selected by means of a rotating switch on the front panel. In any case of overload, including direct short, a current sensing circuit-breaker mounted on the front panel will operate and disconnect the output voltage. Outputs are taken from colour coded 4mm sockets mounted on the front panel. An illuminated on/off switch is mounted on the rear panel adjacent to a fused appliance inlet.

  • Housed in robust metal case with a durable powder coated finish
  • Supplied with mains lead and instructions
  • Dimensions (L x W x H): 179 x 190 x 85mm
  • Weight 2.8kg
