Contactless voltage regulator
The AVR contactless AC voltage regulator is a stable voltage source that uses the ARM new generation 32 bit processor as the core, SCR as the actuating component and the compensation transformer as the voltage compensation mode.

It mainly solves the voltage problems such as large voltage fluctuation, unbalanced three-phase voltage and load voltage drop frequently。

Optional isolation transformer, LC filter, ATS dual power input, SPD lightning protection module, multi channel power distribution.
Voltage bidirectional compensation, to solve the problem of too high voltage or too low.
No contact, no carbon brush, no machinery, no motor, no maintenance.
The dynamic response and the speed of stability are fast.
High power factor;
High efficient;
LCD parameters display, simple and easy to understand;
RS232 communication interface, standard MODBUS-RTU protocol, optional TCP/IP interface, remote viewing and control through mobile phone APP.
