Overview
About GPR-H Series Linear DC Power Supply
The GPR-H Series linear DC power supply provides 0.01% regulation with low ripple and noise output, essential for powering sensitive analog circuits, precision sensors, and RF front-end modules during development and production test.
Constant voltage and constant current operation modes with internal selection for continuous or dynamic load support both steady-state and transient load applications. Overload protection and reverse polarity protection safeguard the DUT.
Available in power ratings from 240W to 375W with voltage ranges spanning 0–75V through 0–300V, the series covers applications from bench-level prototype testing to production line power sourcing. The linear topology eliminates switching noise, making GPR-H the preferred choice when measurement sensitivity demands the lowest possible supply noise floor.

Battery Simulator vs Battery Emulator: Hardware for BMS and Pack Testing
The bench instrument whose terminals behave like a battery pack, why a plain DC supply leaves BMS code paths unexercised, and the capability list to specify against. Worked through the GW Instek RBS Series battery simulation function.
BESS Test Benches: Rack-Level Charge and Discharge Qualification
The bench that qualifies a storage rack: which voltage classes rack buses land in, the current envelope at top of charge, parallel growth in the class you buy first, and cycling that runs unattended for weeks.
Motor Drive Test Benches: DC Bus Supply and Regenerative Braking
A motor drive bench powered at its DC link terminals needs a bus that supplies the drive and takes energy back when the motor brakes. How one bidirectional source, sized against the real bus voltage, replaces the supply, blocking diode and load.
