Applications
Power electronics engineers use the GPM-8320 Series for characterizing power supplies, motor drives, lighting systems, and inverters. The three-phase measurement capability covers industrial motor testing, three-phase UPS validation, and grid-connected inverter efficiency measurement. Real-time power factor and harmonic data support energy audit requirements and compliance testing against IEC power quality standards.
Production test environments benefit from the remote control interfaces for integrating power measurement into automated test sequences, enabling high-throughput testing of power conversion products on manufacturing lines.
GSAS Micro Systems provides the GPM-8320 Series across India with technical consultation for power measurement applications and local support.

AI Data Center Testing: Power Shelves, Busbars, Burn-In and Optics
AI racks fail on the bench long before they fail in the field. How AI data center infrastructure is actually tested: server power shelves and CRPS supplies, 48V busbars, battery backup units, DC-DC stages, burn-in, thermal validation, high-speed switches, and optical transceivers, mapped to the GW Instek instruments GSAS supplies across India.
Testing High-Power UPS, Solar Inverters and Power Electronics: Inside the GW Instek AEL-5000 AC/DC Electronic Load
India's UPS, solar-inverter and power-electronics makers need load testing that behaves like the real world: non-linear, high-power and scalable. Here is how the GW Instek AEL-5000 AC/DC electronic load covers it, from 1.875 kW on the bench to 540 kW in a three-phase array.
Automated EV Charger Test Bench in India: GW Instek AC Source, DC Load and Battery Emulator
A walkthrough of an automated test bench that validates a CAN-controlled EV scooter charger across the full Indian grid envelope. GW Instek's APS-7200 AC source, PEL-3111AH DC load and GPP-7250 battery emulator combine with a Total Phase Komodo CAN Duo BMS emulator for unattended, repeatable charger validation, designed, integrated and scripted in India by GSAS.
