Adopted advanced sine energy distributing technology, thee main circuit is constructed by paralleling the sine energy distributor and the high power filter. When the output voltage Uo is changed because of the undulation of the supply voltage or the load, it control the SCR elements angle through sampling circuit, comparer and trigger unit to change the current which lead to the variety of the compensating voltage ΔU and the phase, and reach to the target of stable output voltage. It has excellent regulation and anti-interference function with digital display; the regulation accuracy reaches to ±1% and the response time <0.1s, it can restrain the peak interference of electric network effectively, efficiency of this machine >90%.

These equipments and facilities that has higher requirement for the electricity quality as computer, precision instrument, copier, inspection device, communication broadcasting device, auto control
system and so on.

1. Wide regulation range: single-phase185V~255V, three-phase320V~440V;
2. High regulation accuracy: <±1%;
3. Strong anti-interference ability: can restrain various noises and peak voltage in the electric network;
4. Short response time: <0.1s;
5. High efficiency: >90%;
6. Test functions of the output and input voltage are clear and visual.
