DBW Serie einphasige Spannungsstabilisator

DBW series single phase Full Automatic compensated voltage stabilizer General It can keep output voltage in steady state automatically when the power network voltage fluctuates or the load current varies.Compared with other voltage stabilizers,it has the advantage of large capacity,high efficiency,no wave distortion,stable voltgae adjustment,suitability for kinds of loads,bearing instantaneous overload,working contiunally for long time, as well as free transferring between manual control and automatic control,etc,bessides,it is provided with protection against over-against over-voltage,over current,phase failure and protection for phase sequence and has following merits:samll volume,light weight,convient installation and reliable running and so on The product is used indoors,the normal service conditions for it as follows: Temperature environment: -15 + 40;Altitude: less than 1,000m;Relative humidity:90%No gas,steam,chemical precipitate,dust,dirt or any explosive or corrosive mediem,which can seriously affect the insulation of voltage stabilizer in the installation place.No serious vibration or jolt in the installation place. Main Technical charateristics Input: Single: 220V±20% or 220V±30%.it can be selected(please indicate when placing an order)Output:Single phase 220V Accuracy of output voltage: 2-5% (Adjustable)Efficiency: ≥95% (power class:more than 50KVA)Respones speed: ≤1.5S( when outside voltage has 10% of change)Waveform distortion:no additive waveform distortionProtection: protecction against over voltage,over current,phase failure and machine fault,as well as phase sequence prtection(single-phase and three-phase 150KVA below has no phase failure and is provided with phase sequence protection.)Voltage stabilization,convient switching for commericial power(single phase has no function.Start automatically or by hand(can be chosen)when power is on.Can work continuously for a long time without anybody attending.Insulation resistance: ≥2MElectric strength:bear power frequency sine voltage 2,000 V for 1min without breakdown or flash over.Overload capability:2times rated current,keeping 1 min (voltage stabilizer special for elevator and CT) Model & Spec ModelRated capability(KVA)Output max current(A)Size(mm)D×W×HCabinetQTYWeight(kg)DBW-10 1045500×650×1320 1270DBW-15 1568500×650×1320 1275DBW-20 2091500×650×1320 1283DBW-25 25114500×650×1320 1300DBW-30 30136500×650×1320 1310DBW-40 40183500×700×1500 1330DBW-50 50227620×800×1500 1360DBW-60 60273620×800×1500 1365DBW-80 80364680×920×1620 1480DBW-100 100455680×920×1820 1490DBW-12 120545680×920×1820 1496DBW-150 150628680×920×1750 1530DBW-180 180818680×920×1750 1540DBW-200 200909680×920×1750 550
