The PSW Series from GW Instek is a high-performance, single-output programmable DC power supply designed for demanding R&D, production testing, and system integration applications. Featuring multi-range operation up to 1080W, flexible voltage/current combinations, and advanced DUT protection capabilities, the PSW Series delivers precision, efficiency, and scalability in one platform.

With support for series and parallel operation, remote interfaces, and programmable control, it is ideal for testing LEDs, batteries, power modules, and high-current devices.

The PSW Series is engineered to provide maximum flexibility and protection in modern power testing environments. Its multi-range architecture allows users to operate across a wide combination of voltage and current without being limited to fixed ranges, significantly reducing the need for multiple power supplies.

Advanced protection features such as C.V/C.C priority control and adjustable slew rate help prevent damage to sensitive devices during testing. With built-in USB and LAN interfaces, the PSW Series integrates easily into automated test environments and production systems.

Calibration & Support
Optional calibration services are available through TestEquity to help maintain measurement accuracy and ensure compliance with quality standards over time.

Frequently Asked Questions (FAQ)

1) What makes the PSW Series different from a standard DC power supply?
The PSW Series from GW Instek uses multi-range operation, allowing one unit to cover a wider range of voltage and current combinations—reducing the need for multiple power supplies.

2) Can I increase voltage or current output?
Yes. You can connect up to 2 units in series to increase voltage or up to 3 units in parallel to increase current, depending on your application.

3) How does the PSW Series protect my device under test (DUT)?
It includes C.V/C.C priority mode, adjustable slew rate, and built-in protections (OVP, OCP, thermal) to help prevent inrush current and damage during testing.

4) What interfaces are available for remote control?
Standard interfaces include USB and LAN. Optional adapters are available for GPIB and RS-232 for additional system integration.
