Product introduction



Wisman's MRD series are modular high-stability and precision high-voltage power supplies. The MRD series module power supply has good regulation performance, and provides positive or negative high voltage output. The MRD series module power supply can be internally, externally, precisely measured and controlled by a computer, and USB2.0 and RS-422 digital control interfaces are optional. MRD series module power protection includes overvoltage, overcurrent, arcing, safety interlock, etc.
