Contactless compensating voltage regulator
● Product Overview
The ZBW (ZSBW) series single and three-phase microcomputer controlled contactless compensation power stabilizer is a new high-power AC stabilized power supply designed by our company based on China's national conditions. This product is based on advanced power electronics and computer digital fuzzy control technology, abandoning the carbon brushes and mechanical structures of ordinary voltage regulators, and integrating advanced combination winding compensation methods, contactless switches, and microcomputer controlled AC voltage stabilization technology. This voltage regulator has made a breakthrough in solving the damage caused by conjugate current surge and overvoltage generated by non-contact switches during the transient process of system and device operation. It has strong instantaneous overload capability, greatly improving the reliability of system operation. Its friendly LCD display screen facilitates user operation and query. Applicable occasions: various CNC machining centers, medical equipment, printing machinery equipment, environmental testing equipment, electronic detection equipment, communication equipment, etc., especially suitable for harsh power supply environments such as large fluctuations in the power grid and sudden voltage changes.
