DBW AC automatic stabilizer
Advantages : 1, small size, light weight, suitable for long-distance transport, reduce your transportation costs; 2, whole no contact, no brush, no wear, no maintenance once installed; 3, a wide input voltage range can be customized non-standard ± 60% input voltage range;
4, high output voltage accuracy ± 1%;
5.The AVR’s can match any load type, especially unmanned operation of equipment in telecommunication centers:
6, the regulator is fast, able to adjust the voltage within 40ms of work; 7, three-phase independent control of voltage, non-interfering, anti-lightning. 8, is widely used in communication base stations, telecommunications / broadcasting network, highways, machinery and equipment

Working principle
This series of stabilizer by compensate circuit, voltage measure circuit, electric furnace, servo motor in back control circuit and main circuit slowdown, the transmission structure switch operation circuit, voltage, measure current and protection circuit component.
Product warranty:
1) stabilizes run before please read the instruction and know its performance, function and use conditions.
2) load current is not exceed allowable values.
3) input voltage within permitted, output voltage instability should check immediately.
4) regulators should be installed in the clean and dry and ventilated a cool place. To ensure that when using, and remember: will not overheat
This machine though can be installed in room temperature 40 °C environment, but the long-term effects in this temperature, can lead to semiconductor zero
A change and permanently damaged, thus reduces its reliability. To be on the safe side, we suggest using at room temperature
25 °C in the most appropriate within.
5) cleaning the stabilizer, each place no dirt, cleaning the dust when application gasoline and cotton cloth to wash dry.
6) found defective or damaged components should be timely repair or replacement.
