# 6428B Agilent DC Power Supply Used

**Additional Features:**

-   Voltage: 0-20V
-   Current: 0-45A
-   Power: 900W
-   Output continuously variable to zero in either voltage or current modes
-   Efficiency up to 75% at full output
-   Excellent line transient immunity
-   Low output ripple
-   Constant Voltage/Constant Current operation with automatic crossover

The Agilent HP 6428B utilizes silicon-controlled rectifiers in series with the transformer primary. Controlled by the output voltage and current settings, these supplies accomplish the desired regulation using a ramp-lock phase control circuit. This circuit technique permits a reduction in the overall size and weight of the power supply and results in up to 75 efficiencies at full output.
