Not only does the Agilent HP 6443B used Power Supply have great advantages such as the output is continusuously variable to zero in either voltage or current mode, effeciency up to 75% at full output, and excellent line transient, these used power supplies provides a voltage rating of 0 to 120 V, and a current rating of 0 to 2.5 A.
Controlled by the output voltage and current settings, these used power supplies accomplishes the desired regulation using a unique "Ramp-Lock" phase control circuit. 115 AC ±10%, 57-63 Hz.
