Overview
About PFR-100 Series
The GW Instek PFR-100 Series is a fanless multi-range DC power supply delivering 100W with natural convection cooling, eliminating fan noise entirely for use in acoustically sensitive test environments such as audio equipment development, anechoic chambers, and quiet cleanroom facilities. Constant power output across fivefold multi-range voltage and current operation maximizes the usable operating area from a single 100W instrument.
Model Comparison
| Model | Power | Voltage | Current | Target Application |
|---|---|---|---|---|
| PFR-100L | 100W | 0 - 50V | 0 - 10A | Low-voltage, high-current |
| PFR-100M | 100W | 0 - 250V | 0 - 2A | Higher-voltage, lower-current |

CV/CC priority mode allows engineers to select whether constant voltage or constant current takes precedence during load transients, which is particularly useful for battery charging applications and LED driver testing. Adjustable slew rate for both voltage and current provides controlled output transitions, preventing inrush damage to sensitive DUTs. Preset memory and output on/off delay functions streamline repetitive test workflows.
A built-in web server enables browser-based monitoring and control from any networked device, while external analog control and monitor functions support integration with custom test fixtures. Front and rear panel output terminals offer flexible connection options for bench and rack-mounted configurations.
GSAS Micro Systems provides the PFR-100 Series across India with application engineering support, calibration services, and prompt delivery.

GW Instek Insights
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.
