ZBW series of non-contact AC Voltage RegulatorProduct IntroductionZBW series intelligent non-contact ac stabilizer is self-developed and self-manufactured by our company, which has international advanced level. Basing on the particular order, it adopt sintegration and controls several thyristor voltage zero-crossing on and off to change the size and polarity of compensating voltage, is the perfect combination of thyristor AC switch technology and transformer technology, and has the advantages of good stability and efficiency, non-pollution to power network, can work continuously and reliably under all kinds of harsh and complex load, the service life is very long, can continuous trouble-free operation more than 100,000 hours, realized the stabilizer long-term free maintenance.Technical SpecificationInput VoltageRegulators scopeThree Phase304V-456V,One Phase176V-264VFrequency50HZ/60HZOutput VoltageRated voltagePhase Voltage 220V,Line Voltage 380VRegulators accuracy±(1-5)% option(±2.5%for the conventional)Response time≤10msWaveform distortionDo not produce additional waveform distortion(static)Efficiency≥98%Three-phase imbalanceAutomatic three-phase voltage balanceDelay outputAgain from the first regulator(protective equipment  without shocks)OvervoltageThe output voltage of more than 10%(245V),or cut output to bypass uninterruptedUnder voltageThe output voltage of less than 10%(195V),or cut output to bypass uninterruptedProtectionLack of phaseautomatically cutOverloadElectronic detection, within three minutes overload cut outputShort circuitDual electronic detection and protection circut breakersOver currentDual electronic detection and protection circut breakersBypassManual or automatic bypass uninterruptedLightsVoltageA,B,C,respectively, with three-phase   ABC TRMS figures showCurrentA,B,C,respectively, with three-phase   ABC TRMS figures showWorking conditionsRegulators stae/bypass stateAbnormalOver-voltage, under-voltage, overload, fuse faultWork methodsThe two regulators are working methods and bypassOverloadFive times the rated current 1 secondsWork PrincipleUsing microcomputer(MCU+12-bit high-speed AD PLD) intelligent detection, electronic control module output directive (IGBT or SCR)Fast switching through the same frequency transformers, phase-locked, sine wave superposition compensation maintain output voltage stability. Fast response, No Carbon Brush, No contact, no machinery, automatic three-phase voltage balance.  Fast responseTwelve high-speed AD collection, collecting 64 points a week-wave, digital processing MCU computing, electronic modules rapid compensstion.Multiple adjustment formula can be setThe same tune: When ses with the tune, while AD Acquisition A,B,C the true RMS voltage three-phase conducted average, gives instructions for compensation can effectively improve the imbalance of the three-phase voltage.The tune: When set the tune, each three-phase voltage adjustment to ensure the accuracy of three-phase voltages are within   the framework of three-phase voltage imbalance in the power grid, we can balance three-phase voltage, Particularly suitable  for single-phase load.Automatic judgment: microcomputer automatic analysis should be conducted at the same tune or transferred.Advanced Measurement Technology12AD acquisition, digatl filtering and SCM TRMS calculation.The adduracy controlLarge-scale programmable logic device and MCU with the perfect.Human interfaceThrough touch button operation panel can set various indicators(output voltage regulator accuracy and protection).No output waveform DistortionUsing non-contact switch is switched off, the same frequency, with the wave phase-locked compensation superposition principle.Harmonic interference resistanceTrue RMS voltage detection.Wide LoadResistive, capacitive, inductive load can adapt.Starting ease impactA first regulator to output.Full protectionWhen there overvoltage, under-voltage, in one second or in the protection of automatic conversion to bypass  uninterrupted work, and the lack of sound, overload, short-circuit protection and faul after the sound and  light alarm function.Voltage and current showsVoltage, current figures show that were true RMS.ZBWB series of non-contact AC Voltage Regulator(with transformer) In order to adapt to different countries voltage standard equipment, special PSA has been developed regulator that integrates, No Carbon Brush, No contact, no machinery, the three-phasetransfer. Specifications and performance characteristics and ZBW series the same, and its dimensions can be customized according to different capacity. ZBWJ series of non-contact AC Voltage Regulator(Purification) The rapid economic development, industrial equipment continues to increase, and made China's growing shortage of power supply, power grid quality getting worse. There overvoltage, lessvoltage, and instantly the sharp pulse, and instantly fell, equipment inter-EMI electromagnetic interference, and other conductive anomalies. Ordin
