Chroma 62150H-600S Solar Array DC Power Supply

Overview

The Chroma 62150H-600S is a solar array simulation DC power supply designed for testing photovoltaic inverters, renewable energy power conversion systems, and hybrid vehicle battery chargers. Operating at 600V/25A with 15kW output in a compact 3U form factor, it enables high-power density testing on benchtop or in standard racks. The unit provides precision voltage and current readback, programmable I-V curve simulation including shade conditions, and support for complex DC transient waveforms to validate device behavior under fault and transient conditions.
