Chroma 62180D-100 DC Power Supply

Overview

The Chroma 62180D-100 is a programmable bi-directional DC power supply that functions as both a power source and a regenerative electronic load. Designed for testing renewable energy power systems, electric vehicle chargers, power conversion equipment, and battery simulators, this unit can both supply power to and absorb power from the device under test (DUT). With 100V/180A output and 6kW total power, it integrates active power factor correction (PFC) greater than 0.98 for efficient operation. The device features an intuitive touchscreen interface for easy programming and real-time monitoring of voltage, current, and waveform parameters.
