Kepco BOP500M

The Kepco BOP 500M is a high-voltage bipolar operational power supply and amplifier engineered for precision applications requiring both sourcing and sinking capability. It operates in voltage-stabilizing or current-stabilizing modes with independent control channels for local or remote operation. The Class A output stage delivers bidirectional response from zero, ensuring linear transitions across the full rated voltage and current ranges with no polarity switching.
