PSU Series

The PSU Series delivers high power programmable DC output up to 6000W in a compact 3U rack-mount form factor, with voltage models spanning 6V through 600V to address diverse DUT requirements. Autoranging output provides optimal voltage-current combinations across the full power envelope, maximizing utilization without manual range switching.

Scalable parallel operation allows multiple PSU units to combine for higher power capacity, making the platform suitable for EV battery charging simulation, fuel cell stack testing, electrochemical processing, and high-current semiconductor burn-in. The autoranging output is particularly valuable in applications where the voltage-current operating point varies across a test sequence, as it delivers full rated power across a wide range of V-I combinations without manual range changes.

Constant voltage and constant current modes with automatic crossover, along with programmable OVP/OCP protection, ensure safe and precise power delivery. Production test engineers, battery system integrators, and industrial process engineers rely on the PSU Series for its combination of high power density, flexible output range, and remote control capabilities. RS-232, RS-485, USB, and LAN interfaces support automated test system integration and remote monitoring in production environments.

GSAS Micro Systems offers the PSU Series with power system sizing consultation, rack integration support, and calibration services for production and R&D deployments.
