DBW / SBW High Power Spannungskonstanthalter

DBW/SBW High Power Voltage Stabilizer DBW/SBW High Power 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. Input voltageThree-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 voltagePhase voltage:220V Single-phase:220V Line voltage:380VOutput voltage accuracy2-5%(can be adjusted)Frequency:50HZ/60HZEfficiency≥98%(Power grade is over 50KVA)Ambient temperature-10 +40°CInsulation resistance≥2MΩElectric intensityThe voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minuteOverload CapacityIt can last 1 minute at the rated current of two timesWave form DistortionNo additional waveform distortionProtective functionit 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 failureResponse speed≤1.5s(in the condition that the external voltage changes is 10%) Specitications and model
