GW Instek GPP-3323 (LAN+GPIB) Programmable DC Power Supply

Overview

The GW Instek GPP-3323 is a versatile programmable DC power supply featuring three independent output channels. Two channels provide variable 0–32V/0–3A outputs with tracking capability, while the third channel offers fixed voltage selections (1.8V, 2.5V, 3.3V, 5.0V) at up to 5A. With maximum output power of 217W, high-resolution measurement (1mV/0.1mA), and multiple communication interfaces, the GPP-3323 suits laboratory testing, production verification, and complex power sequencing applications.

Key Features
