Dynamic Voltage Restorer
DVR Dynamic Voltage Restorer is a high technology multipurpose power supply, which uses the new generation 32 bit processor of ARM as the core, the IGBT module is the executive component, and the isolation transformer is used as the isolating filter element.


DVR Dynamic Voltage Restorer mainly solves the voltage interruption and voltage drop of the grid voltage. Compared with UPS, it has the advantages of no battery and no maintenance.
 Using AC-DC-AC inverter, the output power is pure sine wave.
 The input and output are completely isolated and are not disturbed by input power grid harmonics.
 Dynamic response and stable speed, input voltage fluctuation stability speed 2ms.
 Electrolytic capacitor or super capacitor energy storage, no battery free maintenance.
 To solve short time power interruption and drop.
 The three phase lack of one phase can work normally for a long time.
 It has the function of automatic correcting output phase sequence, which is especially suitable for two power supply without considering the phase sequence of standby power supply.
 LCD touch-screen 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.
