Product descriptions from the supplier
ZBW Three phase non-contact regulator is a new generation of intelligent fast energy -saving regulated power supply designed by our company which absorbed foreign advanced technology and combined with China ‘s national conditions to stabilize AC voltage. The central control system of the voltage regulator adopts intelligent control of single-chip microcomputer and is equipped with multi-language liquid crystal display, which highlights the safety, stability, energy saving and humanized human-machine interface of the device, Compared with traditional compensation regulators, ZBW series non-contact regulators have three significant advantages: intelligent control and display, fast voltage regulation, and quiet energy saving.
ZBW Three phase non-contact regulator in mainly composed of compensation transformer (controllable transformer), thyristor non-contact switch, high speed AD sampling and intelligent processor composed of single -chip microcomputer. No carbon brush, no contact, no mechanical transmission, digital intelligent control. 12-bit high -speed AD acquisition 128 points per week, single chip digital processing and RMS calculation, accurate control, large-scale programmable logic device and microcontroller. User friendly human machine interface: you can view and set various indicators of the regulator through the touch panel.
