Product introduction


Wisman's MSB is a multi-channel output high-voltage power supply system, the system can output up to 512 channels, and each channel can be used as an independent power supply after being disassembled independently. The system can individually control each channel through the front panel, and the front panel has the voltage and current display head of the channel; the system can also be remotely measured and controlled through a computer, and the RS-485 communication interface is standard. The unique linear power conversion technology ensures the ultra-low ripple of the system. This series of modules has protection functions such as overcurrent, arcing, and short circuit protection.


1. The system can output up to 512 channels, 2-512 channels are optional.

2. AC/DC output voltage 1kV~30kV, output power 2W~20W.

3. Ripple voltage: <2ppm,10mV MIN.
