Overview
About SPS Series
The GW Instek SPS Series is a switching DC power supply delivering 0.01% high regulation with constant voltage and constant current operation. Dual digital panel meters provide simultaneous readout of output voltage and current, enabling efficient monitoring during bench testing and production applications. High efficiency and high power density keep the form factor compact while delivering substantial output current.

| Operation | Constant voltage / constant current |
| Display | Dual digital panel meters |
| Protection | Overload and reverse polarity |
| Efficiency | High efficiency, high power density |
The 0.01% regulation ensures stable output voltage under varying load conditions, which is critical for powering precision analog circuits, calibration reference systems, and sensor arrays where supply voltage accuracy directly affects measurement quality. Overload and reverse polarity protection prevent damage from accidental wiring errors or load faults, making the SPS Series reliable in production environments where multiple operators handle the equipment.
Five models span a range of voltage and current combinations from 12V/30A for high-current low-voltage applications to 60V/6A for higher-voltage requirements. This allows engineers to select the optimal model for their specific application, whether powering automotive ECU prototypes, driving DC motors, supplying embedded systems, or providing regulated rails for component characterization.
GSAS Micro Systems supplies the SPS Series across India with competitive pricing, application guidance, and after-sales support.

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.
