GPD-2303S Series Programmable Linear DC Power Supply

The GW Instek GPD-2303S Series is a multiple output programmable linear DC power supply with digital panel control for precise and repeatable voltage and current settings. Available in two, three, and four-channel configurations, each channel provides 0-30V / 0-3A with 1 mV / 1 mA display resolution. The coarse/fine volume control system enables rapid setting with fine adjustment, while four save/recall memory sets allow instant switching between frequently used test configurations.

Model Comparison

Applications

The GPD-2303S Series is an effective bench supply for embedded systems development, where multiple independent voltage rails, such as 3.3V logic, 5V peripherals, and 12V actuators, must be provided and controlled simultaneously. Tracking series and parallel modes enable channel combination for higher voltage or current output without external wiring, extending the supply’s versatility for a wide range of test scenarios.

The smart cooling fan operates at reduced speed during low-power conditions, minimizing acoustic noise in laboratory environments. Key-lock and warning buzzer features prevent accidental parameter changes during critical tests. The standard USB interface enables remote control and data logging from a PC, supporting integration into automated test setups for production and quality assurance workflows.
