ZBW Series Non-contact Voltage stabilizer(Standard Model)
ZBW serie intelligent no-contact AC voltage stabilizer is new AC stabilized voltage supply researched and developed by Shanghai Nooyi, which meets high quality precision equipment’s special needs for power supply. It has the advantages as fast response, high stabilized voltage precision, no carbon brush, no contact, no machinery, maintenance-free, automatic balance of three-phase voltage, etc. It is the upgrade product of SBW series mechanical voltage stabilizer.
With CE certificate, SONCAP certificate, SARFT Network Access License and test certificate of State Bureau of Quality Technical Supervision, etc. It is broadly used in machine, medical equipment, printing equipment, radio and television communication system and other fields, and highly commended by customers.

ZBW series voltage regulator uses 192*64 liquid crystal display (optional touch screen display), through LCD screen, it can directly display parameters such as voltage, current, fault state, working mode and so on. Its stabilizing precision, output voltage, working mode and so on can be set by the panel, and the operation is simple.

Human interface offers handily operation

Fast response speed

12 bit, high speed AD collection, weekly wave acquisition 128 points, single-chip digital processing 
operation, electronic module rapid compensation 

Multiple regulated

ways can be set 

Coherence adjustment: when set coherence adjustment, AD will collect the true RMS of A, B, C 
three-phase voltage for average calculation, send order to compensate and effectively improve the
unbalancedness of three-phase voltage 

Separate adjustment: when set separate adjustment, three-phase voltage will have separate adjustment,
 ensure that three-phase voltage are within precision range, especially suitable for single phase load
