Kepco MPS620M

The Kepco MPS620M is a three-output linear DC power supply for laboratory and ATE applications requiring precise voltage and current control across multiple rails. The unit combines a high-current 6V primary output with dual tracking ±20V outputs, all adjustable via front panel controls. Each output section includes independent current limiting and protection circuitry. Operating from selectable AC mains (105-125V or 210-250V, 50-440 Hz), it delivers stable, low-noise power suitable for IC testing, microprocessor development, and system integration.
