The GW Instek GPD‑2303S/3303S/4303S series DC power supply user manual provides safety guidelines, operation instructions, remote control commands, and full…
This manual covers safety precautions, installation, and operation of the GPD‑2303S/3303S/4303S series DC power supplies. It explains the three output modes—independent, series, and parallel—and details front‑panel controls, remote‑control procedures, and error handling.
The document also lists the electrical specifications, recommended operating environment, and optional accessories such as USB and test leads. A troubleshooting section answers common user questions and provides contact information for technical support. This manual is written in Chinese.
| AC Input Voltage | 100‑120‑220‑230 V ±10%, 50/60 Hz |
|---|---|
| Output Channels | 4 independent channels (CH1‑CH4) |
| Voltage Range (Independent Mode) | 0 ~ 30 V per channel |
| Current Range (Independent Mode) | 0 ~ 3 A per channel |
| Series Mode Voltage Range | 0 ~ 60 V, 0 ~ 3 A |
| Parallel Mode Current Range | 0 ~ 6 A |
| Voltage Ripple | ≤ 1 mVrms (5 Hz‑1 MHz) |
| Voltage Regulation (≤ 3 A) | ≤ 0.01 % + 3 mV |
| Current Regulation (≤ 3 A) | ≤ 0.2 % + 3 mA |
The output key is not controlled by the panel lock key, so locking the panel does not affect output operation.
Saved settings default the output to the "off" state for safety, so the output remains off after recall.
