Specifications
DBW/SBW automatic voltage stabilizer1:rate capacity :10-2000KVA
2:Input: 380+/-30%
3:output: phase voltage: 220V/380v
voltage stabilizer Application :
Widely used in the fields of post office,store,elevator,hospital,school,publishing house and stock exchange where normal voltage is in need,and also can be used in the factories of large and middle-scale industrial and mining corp,it is very much suitable for some important devices and supporting single machine.
Technical Index
| Input voltage | Three-phase four-line system phase voltage:220±20% line voltage:380±20%,or phase voltage:220±30% line voltage:380±30%(can be selected.Please specify when ordering) Single-phase:220±20% or 220±30%(can be selected.Please specify when ordering.) |
| Output voltage | Phase voltage:220V Single-phase:220V Line voltage:380V |
| Output voltage accuracy | 2-5%(can be adjusted)Frequency:50HZ/60HZ |
| Efficiency | ≥98%(Power grade is over 50KVA) |
| Ambient temperature | -10~+40°C |
| Insulation resistance | ≥2MΩ |
| Electric intensity | The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute |
| Overload Capacity | It can last 1 minute at the rated current of two times |
| Wave form Distortion | No additional waveform distortion |
| Protective function | it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure |
| Response speed | ≤1.5s(in the condition that the external voltage changes is 10%) |
