The maximum output power of the GPP series is 217W. The multi-channel programmable DC power supply includes four models: GPP-1326 single channel (0~32V / 0~6A), GPP-2323 dual channel (CH1: 0~32V / 0~3A , CH2: 0~32V / 0~3A), GPP-3323 three channels (CH1: 0~32V / 0~3A, CH2: 0~32V / 0~3A, CH3: 1.8V, 2.5V, 3.3V, 5.0 V / 5A), GPP-4323 four channels (CH1: 0~32V / 0~3A, CH2: 0~32V / 0~3A, CH3: 0~5V / 0~1A, CH4: 0~15V / 0~1A ). This series not only provides programmable high resolution (1mV / 0.1mA) and readback resolution (0.1mV / 0.1mA), but also has the best low ripple noise characteristics ≤350uVrms/≤2mArms, transient output response time ≤50uS, providing independent output switches for each channel.
