The charging technique with L-C constant-current converter is adopted, and the repeated charging and discharging process of the device is controlled by voltage feedback.

A programmable slew rate allows a controlled transition from one load setting to another to minimize induced voltage drops on inductive power wiring, or control induced transients on a test device.

It is a voltage-controlled device with high input impedance, which makes it possible to control higher output power with a lower input voltage.
