Providing an output current that stays constant with changes in load impedance, the Model 930 constant-current supply is useful for eliminating problems associated with variable line resistance. The output voltage will vary as necessary to maintain the desired value of constant current through the load. The output current can be set by means of an external potentiometer or by a dc voltage. The unit has an internal regulator and reference circuit to make the output current independent of power-supply variations. The supply voltage can be unregulated and can range from 12V to 32V.
