GPP-3323L | GW Instek

Multiple Output Programmable DC Power Supply, GPP-3323L, GW Instek

The GPP-3323L is a three-channel programmable DC power supply that delivers precise, stable, and flexible output for a wide range of test and development applications. It features two variable channels (CH1 and CH2), each offering 0-32V and 0-3A, and one fixed channel (CH3) providing selectable outputs of 1.8V, 2.5V, 3.3V, or 5.0V at up to 5A-ideal for powering logic circuits or digital components. Engineered for performance, the GPP-3323L provides high programming resolution (1 mV / 0.1 mA) and readback resolution (0.1 mV / 0.1 mA). It also boasts low ripple noise (≤350 µVrms / ≤2 mArms) and a fast transient recovery time (≤50 µs), making it suitable for precision-sensitive tasks. Each channel includes an independent output on/off switch to support safe and controlled operation.

The GPP-3323L offers multiple display modes to visualize channel settings, real-time measurement values, and waveform displays. Its Monitor function allows users to set monitoring conditions, trigger alarms, or halt output to prevent damage to the DUT (Device Under Test). Additionally, the power supply includes an output recorder that logs voltage and current over time to internal memory. Data can be saved in *.REC or *.CSV format and transferred via USB flash drive for further analysis in Excel or other software-enabling convenient review and reporting.
