GPS-2303 Series Multiple Output Linear DC Power Supply

The GW Instek GPS-2303 Series is a reliable multiple output linear DC power supply offering two to four independent isolated channels with 0.01% load and line regulation. The linear design ensures low ripple and noise, making the GPS-2303 Series a dependable choice for analog circuit development, audio equipment testing, and any application where power supply noise must be minimized. Tracking operation with automatic series and parallel modes provides flexibility to combine channels for higher voltage or higher current output as needed.

Applications

The GPS-2303 Series serves as a workhorse bench supply in electronics laboratories, educational institutions, and service workshops. The independent isolated outputs allow simultaneous powering of multiple circuit sections without ground loop interference, while the tracking function enables master-slave voltage control across channels for circuits requiring matched or ratiometric supplies.

Fan speed control circuitry minimizes acoustic noise during low-load operation, maintaining a quiet working environment. The combination of tight regulation, low noise, and multiple isolated outputs makes the GPS-2303 Series particularly effective for powering op-amp circuits, data converters, and RF front-end prototypes where supply noise directly impacts measurement quality. Output voltage and current can be set even when the output is disabled (except on the CPS-2303 variant), enabling safe pre-configuration before powering up sensitive devices.
