SDUR is hybrid power quality device with the main function of stablizing three phase unbalance and switch on/off pwoer. It can work step-by-step,first the current transformer real-time monitoring of the load side of the current, and DSP processing and analysis of this data and calculation of equilibrium required for each phase of the compensation current, then drive the IGBT output, to achieve the object.

Feature:

Main power module inverter adopts international famous brand IGBT devices;

A variety of control modes can be set freely according to demand;

With full protection features including overload, overcurrent, short circuit, the system starts with self-diagnostic function;

Start with a buffer control circuit can be avoided from the start instant excessive input current ;

Divided with independent control, both to balance the load current, but also to achieve single-phase, three-phase reactive power compensation;

Built-in wireless communication module, can achieve remote monitoring and data acquisition;

Device uses the column installation, commissioning maintenance is simple, easy to transport.
