The GPP-4323 power supply belongs to the GW-Instek GPP-series and has 4 channels. The first two channels have an output voltage of 0-32V and an output current of 0-3A. The third channel has an output voltage of 1.8/2.5/3.3/5.0V and an output current of 1A, and the fourth channel has an output voltage of 0-15V and an output current of 0-1A.
The GPP-series from GW-Instek is a series of programmable power supplies with a high program resolution and read back resolution and a low-ripple. This makes the power supplies very accurate. An independent output on-off switch is provided for each channel.
The multi-channel models have an internal circuit that allows the first two channels to be connected in series or in parallel without the need for additional external wiring, providing users with convenience not only in operating procedures but also in a more stable output. The GPP-series offers a variety of display modes, including single or multi-channel setting values, measurement values, and waveform displays. It is also possible to set conditions to protect the DUT. This can be done by means of audible alarms or by automatically switching off the lab power supply at certain set values. Furthermore, this power supply has an output recorder function, which records the voltage/current to the internal memory, and the result can be stored as .REC or .CSV file. The GPP-series also has a sequential output function, which allows users to set the sequential constant voltage (CV) or constant current (CC) load waveform. There are also 8 built-in waveforms.
The GW Instek GPP-4323 has a load function that allows CH1 and CH2 to also be used as a load. CH1 and CH2 can draw a combined max power of 50W. The load can function in CV, CC, and CR mode. Furthermore, the function of both channels can be chosen independently allowing for the use of 2 power supplies, 1 power supply & 1 load, or 2 loads.
The main differences between the models of the GPP-series are shown in the table below.
