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-phase transfer.
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, less voltage, and instantly the sharp pulse, and instantly fell, equipment inter-EMI electromagnetic interference, and other conductive anomalies. Ordinary regulator power supply can no longer meet the requirements of special series has been developed ZBWJ exchange purification regulator power supply.
ZBW shape and size of the same series, the series in ZBW increase on the basis of the following functions(including all indicators ZBW Series):
●Surge protection: 40KA high current peak of several attacks since 8-20 us resume(mine)
●peak inhibition: Admission of 4000V, 8-20us pulse, the output is less than 40V
●filter performance: 15KHZ-20MHZ, different mode 70-100dB, 100dB common mode of high-frequency has a good effect
●purification strong function: the load on power grids can filter out interference, but also filter out the interference load on the power grid
ZBWT series of non-contact AC Voltage Regulator(Non-zero line)
In some special occasions, special equipment, power Grid transformer in PSA , the second triangle side by that the output of zero line(neutral line).In response to this situation grid has been developed ZBWT special series of non-contact, no exchange regulator. Input voltage three-phase three-for the 220V, 200V, 208V, and so on, other technical indicators and ZBW series the same
