  • Specifications
  • Technical
Some equipment has low requirements to the voltage (within 5%), based on the users'suggestion, we developed the ZBW series economic type voltage stabilizer that is featured with compact volume, quick response, brushless, contactless, machinery free,three-phase separated regulation, it is economical and practical. Voltage stabilization accuracy of ZBWL series intelligent contactless AC voltage stabilizer (economic type) is 5%, its outline dimensions, technical indexes and performance features are same as ZBW series.
Various CNC machining centers, medical equipments, printing machineries,environmental test facilities, communication equipments, etc, especially suitable for severe power supply environment such as large grid voltage fluctuation range, abrupt change of voltage, etc; it is applicable for situations that the equipment voltage is different from the power grid voltage; CNC machining centers, medical equipments,printing machineries, environmental test facilities, electronic test equipments,communication equipments and so on with different voltage systems.
Input Voltage
stabilization range
 		Three-phase 304V-456V, single-phase 176V-264V
Frequency 50HZ/60HZ
Output Rated voltage Phase voltage 220V, line voltage 380V
Center voltage ±7%
Accuracy of voltage
stabilization
 		±5%
Response time ≤50ms
Waveform distortion No additional waveform distortion (static)
Efficiency ≥98%
Three-phase
unbalanced degree
 		Three-phase voltage balance automatically
Time delay output Voltage stabilization output first (protect equipment from impact)
Over-voltage When output phase voltage is beyond 10% (245),
it cuts off the output, or turns to bypass uninterruptedly
Under-voltage When output phase voltage is lower than 10% (198),
it cuts off the output, or turns to bypass uninterruptedly
Protection Open-phase With automatic cut off function
Overload Electronic detector, cut off the output in 3min in case of overload
Over-current Dual protections of electronic detector and circuit breaker
Short-circuit Dual protections of electronic detector and circuit breaker
Bypass By manual, or automatic bypass uninterruptedly
Indicator Voltage A, B, C and ΣABC three phases have TRMS digital display respectively
Current A, B, C and ΣABC three phases have TRMS digital display respectively
Working status Voltage stabilization status and utility power status
Abnormal Over-voltage, under-voltage, overload, fuse blowout
Working mode Two modes: voltage stabilization and utility power
Overload capacity 5 times the rated current for 1s
