Overview
About PSB-2000 Series
The GW Instek PSB-2000 Series is a programmable switching DC power supply available in low-voltage (0-80V) and high-voltage (0-800V) configurations with output power from 400W to 800W. Constant power output across multiple voltage and current ranges maximizes the usable operating area, allowing a single instrument to serve applications that would otherwise require separate power supplies at different voltage/current combinations. A 90-degree rotatable control panel enables flexible rack mounting orientation.

Key Features
| Feature | Specification |
|---|---|
| Output Type | Constant power, multi-range (V & I) |
| Series/Parallel | Supported |
| Control Panel | 90-degree rotatable |
| Sequence Function | PC-editable |
| Protection | OVP, OCP, OTP |
| Interface | RS-232C, USB, analog (std), GPIB (opt) |
Series and parallel operation expands the effective voltage or current range beyond a single unit’s ratings, supporting higher-power test scenarios. The PC-editable sequence function enables automated voltage and current profiles for battery charge/discharge cycling, component stress testing, and production burn-in applications. Standard RS-232C, USB, and analog control interfaces provide flexible connectivity, with optional GPIB for integration into established ATE environments.
The dual-channel PSB-2400L2 delivers two independent 400W outputs in a single chassis, addressing test scenarios requiring simultaneous multi-rail power delivery. The high-voltage PSB-2400H and PSB-2800H models extend the output range to 800V for HiPot testing, capacitor charging, and high-voltage device characterization.
GSAS Micro Systems provides the PSB-2000 Series with model selection guidance, test system integration support, and after-sales service across India.

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.
