Alfo electric manufacturer of all kind of automatic / servo controlled voltage stabilizers, air / oil cooled servo voltage stabilizer & aluminum foil transformers /isolation transformers, (range 1 kva to 1000 kva). Alfo servo voltage stabilizer is designed for stabilizing ac voltage and made with advanced technology and on the basis of your country national conditions. It can keep output voltage in steady state automatically when the power voltage fluctuates or the load current varies. Compared with other voltage stabilizers, it has the advantage of large capacity, high efficiency, no wave form distortion, stable voltage adjustment, suitability for kinds of loads, bearing instantaneous overload, working continually for long time, as well as free transferring between manual control and automatic control, etc, besides, it is provided with protection against over-voltage, over current, phase failure and has following merits: small volume, light weight, convenient installation and reliable running and so on. Application (servo stabilizer): Alfo servo stabilizer can be applied to large type electromechanical equipment, metal processing equipment, production line, construction device , elevator, medical equipment, equipment of light and textile industry, air-condition, household appliance and lighting used for industry, agriculture, traffic, military, railroad, scientific culture, etc, where need voltage stabilization.
