Brief Introduction:

ZBW series non-contact compensated voltage regulator use high power thyristor (silicon controlled rectifier) instead of mechanical and carbon brush to control and adjust voltage, which can realize 2000KVA high capacity. Max compensation range is ±50%, efficiency is up to 99%. this type of voltage regulator is the newest regulator which has full protection functions, high reliability and adaptability, continuous working time over one hundred thousand hours without any failure.
