Overview
About PSH Series
The PSH Series programmable switching DC power supply delivers high power factor input with high power density output in a compact form factor. Constant voltage and constant current operation modes with software calibration eliminate the need for external calibration equipment, reducing maintenance downtime.
Built-in self-test verifies instrument health at power-on. Over-voltage, over-current, and over-temperature protection safeguard both the supply and the device under test. Low ripple and noise output suits sensitive analog and mixed-signal test applications.
Standard RS-232C interface enables remote control and automated test integration. Optional GPIB (IEEE-488.2) interface adds compatibility with legacy test systems. LabVIEW driver support simplifies integration into National Instruments test environments.

Emulating Processor Power for Thermal Testing: Why Constant Power
A heat sink or a cold plate is qualified against a watt figure, not a volt figure. This application note explains why a thermal load is driven in constant-power mode, how the bench is built for air and for liquid cooling, and what to confirm before you buy.
CRPS and Rack Power Supply Testing: The Six Tests That Matter
A CRPS module has to hold up under an unbalanced grid, a 0 to 100 percent load step, a surge on the line and a redundancy handover. This application note sets out the six tests, and the one source capability that makes a long feeder reproducible on the bench.
GPU Power Board Testing: DC Input Verification Before Integration
A GPU power delivery board is cheap to reject on a bench and expensive to find in an assembled server. This application note covers the programmable DC input test that screens the board, and the same test applied to incoming server systems.
