The Constant Current Power Supply is a special power supply that holds constant current in the load. If the resistance changes, the voltage changes automatically to hold the current constant. A large meter is provided to monitor the load and it can be switched from mA to then monitor the output voltage. Max current is 30mA and maximum voltage available to maintain 30mA in the load is 30V.DC.
