Compact Power with Silicon Carbide (SiC) Innovation

Utilizing compound semiconductor silicon carbide (SiC) technology, the ASR-6000 Series achieves 6.6 kVA of power in a compact 4U chassis, providing exceptional power density and energy efficiency. Supporting three-phase three-wire or three-phase four-wire AC input configurations, both models deliver AC single-phase and three-phase output, enabling engineers to emulate a broad range of real-world power conditions.

From balanced and unbalanced three-phase outputs to phase-loss simulation and multi-channel operation, the ASR-6000 empowers users to reproduce complex power environments with remarkable flexibility — ideal for testing modern high-power server supplies and industrial power systems.

A Leap Beyond the ASR-3000 Series

While GW Instek’s ASR-3000 Series remains a dependable solution for power testing up to 5 kVA, the ASR-6000 extends that capability to 6.6 kVA, delivering a stand-alone three-phase power source without the need to configure multiple units.

This design simplifies system setup and significantly improves test efficiency for high-power CRPS (Common Redundant Power Supply) server modules. Engineers requiring AC single-phase or three-phase output at 5 kVA and above will find the ASR-6000 Series to be a complete, scalable, and time-saving test solution.
