7075 Fixed 110V DC Power Module

  • The 7075 provides an isolated DC supply. Output is pre-specified between 96 and 144 volts with a current capacity up to 7.5 amps. Output voltage and current are monitored on two analogue moving coil meters, access is from two 4mm shrouded sockets.

    A dedicated power switch enables the supply to be controlled independently from the rest of the console and the power indicator shows when mains power is being applied to the switch.

    If the current exceeds the preset level, the supply will revert to constant current mode, reducing the voltage to limit the power to 800 watts. To avoid arking it is important to connect the test load before switching on and to switch off before removing the load.
