Product introduction



Wisman's MEF series is a dedicated high-stability modular, the voltage is from 1kV to 70kV, can provide up to 350W of continuous power. The MEF series is a 350W modular with AC wide voltage input of 86Vac~265Vac. The front end has a power factor correction circuit with a power factor correction capability of 0.99, and automatic cross control of voltage regulation and current regulation. It has good regulation performance and can provide positive or negative high-voltage output,MEF can be controlled by internal,external and computer with RS-232, RS-485, ETHERNET digital control interface. It has the over-voltage, over-current, arc drawing, safety interlock and other protection functions. MEF can work easily under the most severe conditions.

Output: Various maximum voltage outputs such as 1KV to 70KV are selectable, and 0V to maximum voltage is adjustable.

Voltage control:

Local: The local multi-turn potentiometer can set the output voltage between 0V and the highest voltage.

Remote : An external 0 to 10V control signal can adjust the output from 0V to the highest output voltage.

Current control:

Local: The local multi-turn potentiometer can set the current from 0 to the highest current.

Remote: An external 0 to 10V control signal can set the current from 0 to the highest current.
