Tips: 3-phase voltage stabilizer working principle
- This 3 phase automatic voltage stabilizer is composed with contact regulator, sampling circuit, output voltage, implement electrical-motor and move-arm and so on.
- When the input voltage and overload has exchanged, every sampling circuit go on sampling of respective and comparatively, enlargely in accordance with the result of compared motor is move-distorion of needed and drive the move-arm of regulator adjust the voltage made the output voltage unchanged, there by achieve the goal of regulator voltage. (Please refers to picture 1).
- More than 20KVA large capacity voltage stabilizer power supplies, it adept compensated stricture, reduce the weight and improve the character of export.
- When the input voltage and the overload have exchanged, the servo-type voltage stabilizer is about to auto-move high voltage and it can send out voice. (This is normal).
- Use of finished, please close the power of equipment at first, then close the power of voltage regulator, and please don’t take the switch of voltage regulator conduct the switch of electrical equipment for use.
- The products has over/lack phase protect, sleeted switch. When the sleeted switch press a lock. The regulator is state on over voltage or lock phase, i.e. the phase voltage output is more than 248V or there have not output, this machine cut off the output voltage. When the switch un-press, the stabilizer is still output under the over voltage or lack phase.
- This voltage stabilizer has adopted the auto-air switch as the protection of overload or short circuit, it has test the good conditions, when the products left the factory.
