Kepco BOP72-5M

The Kepco BOP72-5M is a high-speed bipolar operational power supply and amplifier delivering ±72V and ±5A in true four-quadrant operation. It functions simultaneously as power source and sink, sourcing and sinking current across its entire voltage range while passing through zero without polarity switching. Designed for laboratory and industrial test environments, the unit executes rapid programmed changes and arbitrary waveform generation with minimal settling time. Its dual control circuits automatically cross over between voltage and current limits, supported by a zeroable preamplifier and fast programming modes. A 50-terminal rear user port provides complete access to all control signals and status flags, enabling integration into automated test systems and feedback loops.
