Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
Excellent output performance
Powerful and stable, the SPD3303C is able to accurately simulate even very small voltage or current variations, fully meeting the power supply requirements of the load.
- Ultra-high resolution: 10 mV, 10 mA
- Excellent setup and readback accuracy to ensure precise and pure outputs
- Three high-precision power supply independent controllable outputs
- Excellent setup and readback accuracy to ensure precise and pure outputs
- Three high-precision power supply independent controllable outputs
Three output modes for increased output power range
The series-parallel function can combine two power supplies into one power supply, expanding the output power range of a single power supply, which brings convenience in some applications. Each of the three independent power supplies can be individually controlled to switch the output on and off at the same time, which is very convenient to use.
