Dynamic Voltage Restorer
In the power transmission system, when the grid voltage disturbance moment or load faults such as short circuit and so on, will branch voltage sensitive load caused by falling, rising and other issues; this change is very lethal to such as semiconductor manufacturing factory, due to problems caused by the voltage sudden loss of tens of thousands each year. The purpose of DVR is to compensate for the short time voltage drop and rise. It adjusts the voltage quality of the user terminal by introducing a voltage source into the distribution system to suppress the impact of voltage disturbance on the sensitive load of the distribution system.

Product Features:

Human-computer interface
Humanized interface, let your operation be handy!


     
Intelligent display and diagnosis system, including working state, three phase voltage, three phase current, fault display and parameter setting, can be set by LCD and keyboard, and the operation is simple.

Use as UPS

Full power compensation and isolation DVR can be connected to external batteries. When online UPS is used, it is necessary to increase battery charging and monitoring module. If necessary, please specify when ordering.

It not only has the function of UPS's continuous power supply, but also has strong ability to resist interference from input power, and solves the harsh requirements of ordinary UPS to the input power environment.

It is suitable for the power grid with serious interference source and high harmonic distortion. For example, the interference caused by the nonlinear load of steel-making furnace, the frequent start up disturbance of the induction motor in the factory, the voltage rise, the temporary drop and the harmonic disturbance generated by the heavy load of high speed rail and rail transit. A power supply for high density equipment. For example, communication equipment, laser processing machine, precision punching machine, CNC machining center, the production line etc..
