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.
Servo Motor Inrush Current Testing: Method, Limits and Bench
A servo motor draws a large current spike at power-on. This application note sets out how that inrush is measured against a stated acceptance limit, what the DC source has to do, and where the measurement usually goes wrong.
Battery Simulator vs Battery Emulator: Hardware for BMS and Pack Testing
The bench instrument whose terminals behave like a battery pack, why a plain DC supply leaves BMS code paths unexercised, and the capability list to specify against. Worked through the GW Instek RBS Series battery simulation function.
BESS Test Benches: Rack-Level Charge and Discharge Qualification
The bench that qualifies a storage rack: which voltage classes rack buses land in, the current envelope at top of charge, parallel growth in the class you buy first, and cycling that runs unattended for weeks.
Motor Drive Test Benches: DC Bus Supply and Regenerative Braking
A motor drive bench powered at its DC link terminals needs a bus that supplies the drive and takes energy back when the motor brakes. How one bidirectional source, sized against the real bus voltage, replaces the supply, blocking diode and load.
Solar Array Simulation for PV Inverter MPPT Testing
What a solar array simulator does that a bench supply cannot, how static and dynamic MPPT testing differ, and why the presence of a solar array simulation function depends on the model number rather than on the product family. From the GSAS engineering team in India.
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.
How to Buy an Oscilloscope in India (2026): USB vs Benchtop, Bit Depth, Bandwidth: A Buying Guide
A vendor-neutral buying guide for Indian engineering teams choosing an oscilloscope in 2026. How to size bandwidth, sample rate, channels and bit depth; when a USB/PC oscilloscope beats a benchtop; and how oscilloscope price in India actually breaks down once you add GST, probes and warranty. Written for embedded, power and education teams in Bengaluru, Pune, Chennai, Hyderabad, Mumbai and Delhi NCR.
