Overview
About PPX Series Programmable High Precision DC Power Supply
The GW Instek PPX Series is a programmable high precision DC power supply designed for applications demanding ultra-fine measurement resolution. With four ranges of current measurement down to 0.1 µA and two ranges of voltage measurement down to 0.1 mV, the PPX delivers laboratory-grade accuracy in a compact bench-top form factor. The series supports C.V/C.C priority switching, a data log function capable of recording up to one billion data points with configurable sample intervals from 0.001 to 999 seconds, and a test sequence function for automated voltage/current profiling.

| PPX-2005 | 20V | 5A | 100W | General-purpose R&D |
| PPX-3601 | 36V | 1A | 36W | Battery cell evaluation |
| PPX-3603 | 36V | 3A | 108W | Telecom module testing |
| PPX-10H01 | 100V | 1A | 100W | High-voltage device testing |
Applications
The PPX Series excels in semiconductor device characterization, LED testing, battery cell formation, and sensor calibration where micro-ampere level current resolution is essential. The voltage remote sense function compensates for lead resistance, ensuring accurate voltage delivery at the device under test. K-type thermocouple temperature measurement enables simultaneous thermal monitoring during power delivery, which is critical for reliability testing and thermal characterization of power devices.
Standard interfaces include USB, LAN, RS-232, RS-485, and analog control, with optional GPIB for integration into legacy automated test systems. The data logging and sequence programming capabilities make the PPX suitable for unattended long-duration tests in quality assurance and production environments.
GSAS Micro Systems is an authorized partner in India, offering the PPX Series with local technical support, INR invoicing, and GST-compliant billing.

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.
