ZBW series three-phase microcomputer contactless compensation voltage stabilizer

No.Features isolation, anti-interference, steering, non-contact, high power, fast voltage stabilization
ZBW series contactless compensation maintenance-free power voltage stabilizer is a patented contactless voltage stabilizer with international leading level developed and produced by our company.

The ZBW/ZDBW contactless voltage stabilizer uses integrated circuits to control the zero-crossing on and off of several thyristor voltages in a specific order to change the size and polarity of the compensation voltage. It is a perfect combination of thyristor AC switch technology and transformer technology. It uses high-power thyristors (silicon controlled rectifiers) instead of machinery and carbon brushes to control the voltage regulation. The capacity can reach 2000KVA, the maximum compensation range can reach ±50%, and the efficiency can reach more than 99%. It is an advanced product leading the development direction of high-power power voltage stabilizers. It is an energy-saving green and environmentally friendly product with all protection functions, very reliable in operation, and highly adaptable.
It realizes full contactless voltage regulation, has the characteristics of good stability and high efficiency, no pollution to the power grid, can work reliably and continuously under various harsh power grids and complex loads, has a very long service life, can run continuously without faults for more than 100,000 hours, and realizes long-term maintenance-free voltage stabilizers.

Description
■ Working Principle
Adopting microcomputer (MCU + PLD + 12-bit high-speed AD) intelligent detection, output command control electronic module (IGBT or SCR) fast switching, through transformer frequency synchronization, phase locking, sine wave superposition compensation to maintain the stability of output voltage. Fast response speed, no carbon brush, no contact, no machinery, three-phase voltage automatic balance.

■ Features

Quick Response 12-bit high-speed AD acquisition, 64 points per cycle, single-chip microcomputer for digital processing, electronic module for fast compensation
Multiple Adjustment Modes Can Be Set Synchronization: When synchronization is set, AD simultaneously collects the true effective values ​​of the three-phase voltages A, B, and C for average calculation, and gives instructions for compensation, which can effectively improve the imbalance of the three-phase voltage.
Separate regulation: When separate regulation is set, the three-phase voltage is adjusted separately to ensure that the three-phase voltage is within the accuracy range, which is particularly suitable for single-phase loads
Automatic judgment: The microcomputer automatically analyzes whether to perform synchronization or separation
Advanced Measurement Technology 2-bit AD acquisition, single-chip microcomputer for digital filtering and true effective value calculation
Precise and Accurate Control Perfect combination of large-scale programmable logic devices and single-chip microcomputers
User-friendly Interface Various indicators (output voltage, voltage regulation accuracy, protection function) can be set through the touch keys of the operation panel
Output Waveform without Distortion Contactless zero-crossing switch switching, same frequency, phase lock, sine wave superposition compensation principle
Resistant to Harmonic Interference True RMS voltage detection
Wide Load Range Resistive, capacitive and inductive loads can be adapted
Slow Start and Shock Resistance With the function of voltage stabilization before output
Full Protection Function When overvoltage or undervoltage occurs, it can be protected within 1 second or automatically switched to bypass operation without interruption. It also has perfect phase loss, overload, short circuit protection and sound and light alarm function after fault.
Voltage and Current Display Voltage and current true effective value digital display
