Excellent Output Performance
The SPD3303C is robust and stable, and can accurately simulate even small voltage or current changes, fully meeting the power requirements of the load.
- Ultra-high resolution: 1 mV, 1 mA
- Excellent setting and readback accuracy to ensure accurate and pure output
- Support panel programming and timing output
- 3 independently controlled and isolated outputs
Series/parallel/independent Mode
The series-parallel function combines two power supplies into one power supply, which expands the output power range of a single power supply, which brings convenience in some applications. The three independent power supplies can individually control the output switch, and they can be turned on or off at the same time.
