PSU Series

The PSU Series delivers 1200 W to 1560 W of programmable DC output per unit from a 1U 19-inch chassis, across fifteen voltage ratings from 6 V to 600 V. Output runs in C.V or C.C priority with adjustable voltage and current rise and fall times, which is what lets the same supply serve a soft-start requirement and a fast-step requirement without a hardware change. Higher power comes from paralleling up to four units of the same model, and higher voltage from up to two units in series on models under 300 V. See the full GW Instek power supplies range.

Paralleling up to four units of the same model combines their output 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. C.V and C.C priority matter where the voltage-current operating point varies across a test sequence: C.C priority caps current first during a fast step, which limits inrush into a capacitive load, while C.V priority holds the rail. If you need a single supply that re-ranges its voltage and current envelope automatically, that is the PSW Series rather than the PSU, and we will point you there instead.

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.
