ZBW series three-phase microcomputer contactless compensation voltage stabilizer

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.
Multiple Adjustment Modes Can Be Set	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

■ Precautions for Use

This series of voltage stabilizers should be used indoors, and the normal use conditions are:
1,Ambient Temperature：－15℃～＋45℃
2,Altitude not exceeding 1000m.
3,Relative humidity：≤90％
4,The installation site should be free of gases, steam, chemical deposits, dust, dirt and other explosive and corrosive media that may seriously affect the insulation of the voltage stabilizer; the installation site should be free of severe vibration or bumps. Any special use conditions that do not meet the above requirements should be determined by the user and our factory through consultation.

■ Remark
1. Three-phase four-wire system, phase voltage 220V±30%, line voltage 380V±30% (please specify when ordering);
2. ZBW series products all use three-phase voltage regulation separately, with three-phase voltage automatic balancing function;
