KFA10
KFA10
Functions and features:
Adopting advanced phase-shifting resonant high-frequency soft switch technology, the conversion efficiency is high;
The module adopts the output stepless current limiting mode, which can be selected by the system monitoring module according to the load current and battery capacity, and the accuracy of current stabilizing at the current limiting point is better than ±0.5%.
It adopts low difference independent flow sharing technology, and has ideal flow sharing performance when several modules run simultaneously.
It adopts integrated input, output and communication port, and is designed to be live plug and unplug, which facilitates the replacement of modules, making system maintenance safe, simple and efficient.
With complete alarm and protection function;
Can realize communication with upper computer, with "four remote" interface;
Built-in CPU distributed control mode, convenient communication, strong anti-interference ability.
