Product details
Overview
ZBW/SG seriesMicrocomputer contactless compensation powerThe voltage stabilizer is a patented contactless voltage stabilizer independently developed and produced by our company with international leading level,And with isolation function, anti-interference, harmonic filtering, safe and stable.thatContactless voltage regulators use integrated circuits to control the zero crossing and breaking of several thyristors in a specific order, in order to change the magnitude and polarity of the compensation voltage. It is a perfect combination of thyristor AC switching technology and transformer technology. Using high-power thyristors (thyristors) instead of mechanical carbon brushes to control voltage regulation, the capacity can achieve3000KVA， The maximum compensation range can reach ± 40%, and the efficiency can reach over 99%. It is an advanced product leading the development direction of high-power power stabilizers.
Achieved touchless operationstablePressure, with good stability performanceNo noise, maintenance freeThe advantages of fast response time, high efficiency, no pollution to the power grid, and reliable continuous operation under various harsh power grids and complex loadsIt has an extremely long service life and can operate continuously without faults for more than 100000 hours, achieving long-term maintenance free operation of the voltage regulator.
Occasions for use
variousmechanical数控加工中心、Imported precision instrumentsMedical equipment, printing machinery equipment, environmental testing equipment, electronic detection equipment, communication equipment, oil fields, used for harsh power supply environments such as large fluctuations in the power grid and sudden voltage changes.
