Kepco ATE150-7DM

The Kepco ATE150-7DM is a unipolar, linear, programmable DC power supply delivering 500 W across a three-quarter-rack footprint. Built for laboratory, industrial, and system-level test applications, this unit combines precision analog control with digital LCD panel metering for real-time output monitoring. It operates in constant voltage (CV) and constant current (CC) modes with automatic crossover, supported by programmable overvoltage protection and adjustable limiting circuits. The supply accepts local potentiometer control, remote 0-10 V analog programming, and optional IEEE-488 digital interfaces. Two uncommitted internal amplifiers enable signal conditioning and scaling for custom control architectures.
