Key Features
The GPP-3323 (LAN+GPIB) Multi-Output Programmable DC Power Supply is a high-performance, triple-channel power supply designed for precise and flexible DC power delivery in laboratory, development, and production environments. Delivering a total output power of 217W, it features three independent, isolated channels—two channels at 0-32V/0-3A and one channel at 0-5V/0-5A—each with high resolution and low noise. The unit offers advanced features such as series and parallel operation, tracking mode, and sequential output, making it ideal for complex testing scenarios. It supports GPIB and LAN interfaces for seamless integration into automated test systems, and includes USB and RS-232 ports for added connectivity. With a 4.3-inch TFT LCD display, intuitive user interface, OVP/OCP/OTP protection, and high accuracy, the GPP-3323 ensures reliable and safe operation across various applications in electronics, telecommunications, and research.
