Electric UPS Three Phase

1.1 Summary Substation, the important AC equipment in Power plants such as machine background, RTU, transmitters, communications equipment, lighting, and other incidents generally  supply by the uninterruptible power supply (UPS) .However, the general UPS equipment price high , large maintenance , higher failure. Therefore, the electric UPS advantages as following : which can apply with power substations, power plants operating in the DC Power System,and direct use he long-life, high-capacity battery,of DC power operation system, reduce costs, system maintenance, operating costs.The product is single-phase input / single-phase output high-quality uninterruptible power supply. That use advanced SPWM technology, the main circuit use Japan's Mitsubishi IGBT module, and the driver protection use Japan's Mitsubishi thick film circuit , has high reliability, full protection, low waveform distortion .electric supply UPS is specially designed for power plant , transformer station, with online ,zero delay switch protection ,mainly used in the fields of high demand to load such as electric telemechanism , RTU ,DCS system, electric carrier wave ,monitor etc .1.2 Main FeaturesThe BUD series of online UPS for the three-way input: the first way is AC220V/50Hz, the second way is DC 220V and the third way is bypass input AC220V/50Hz.,The output AC 220 V/50Hz.which.compared to the normal UPS, it has advantages as following :                 It will not generate a large electromagnetic interference and has minimal impact to the DC bus because there is a anti-noise suppressor at the DC input.The DC power input of the UPS fitted with anti-anti-blocking diode, So the internaDC operation system work even more safe and stableIt can effective inhibition of the inrush current, longer battery life for the Buffer with DC circuit designThere is a isolation transformer installed in the exchange of power input. So it can meet the DC operation of DC power system on the bus insulation requirements.DC screen commonly used valve-sealed battery, which long-life, and therefore use DC power inverter power source, reliability and long-life ; the capacity of DC battery screen is larger, using inverter power supply, after the utility can supply  AC for a longer time.1.3 Notice This specification allows you to easily operate and maintain the system. You must strictly abide this manual the following requirements.Before use You must be carefully read this statementThe equipment must be installed by professionals.It must be good grounding at the time of installation for avoiding hurting personal safety Not operating in the high humidity or temperature, gas or flammable volatile environment.Switch shutdown of all, do not open the lid closed, so the residual voltage electric shock or cause damage to machinery.Avoid overload, so as to avoid failure UPSThe system maintenance and replacement batteries work must be qualified by technical personnelMachines should be carried carefully.Opened packaging, inventory annex. If found missing pieces or damaged during transport, please contact us, you will be satisfied with the service.2: the system of working principleWhen the utility power normal ,isolate the monophase AC of 220V (triphase 380V ),supply the power for the inverter by rectifier filter, if the Ac input cut off ,the DC screen of provided for  itself of the electric system supply power for the inverter through against converse diode ,Supply the power supply for the mainly load by output isolation , if the DC screen cut off, still have the AC input power supply ,if the inverter over load or fault ,have the static switching change into bypass power supply .Manual maintenance the bypass operation: When the main circuit out of order or require maintenance, the manual bypass switch run, the running mode: preparing  electricity →load.  ModelXND220-3020XND220-3030XND220-3050XND220-3100XND220-3200XND220-3450XND220-3600XND220-31000XND220-32000DC InputOutput rating voltage (VDC)220Output rating current (A)10.115.225..349.499222296496988Input DC voltage allowing range(VDC)180~300AC bypass inputAllowing input voltage range(VAC)380±15%Input rating current(A)3.04.57.615.230.368.491.2151..9303.9Bypass switch time(ms)≤4AC outputRating capacity(KVA)2.03.05.010204560100200Output rating power(KW)1.62.44.08.016364880160Output rating voltage and frequency(VAC/Hz)380VAC/220VAC,50Hz(three phase four wires)Output rating wire current(A)3.04.67.615.230.168.491.2152304Output voltage precision(V)380±3%Output frequency precision(Hz)50±0.05waveform deviation factor (THD)(liner load)≤3%Three-phase load unbalance ability≤100%dynamic response(load 0←→100%)5%Power factor(PF)0.8Load ability150%, 10screst factor(CF)3:1Inverted efficiency (80%resistance load)91%92%Working envirnmentInsulation strength(input and output)2000VAC,1minute Noise (1meter)≤45dBusing condition temperature-10ºC~+50ºCtemperature0~90%,no condensingUsing altitude(m)≤2000machine dimensionwidth,depth,height (mm)550×480×
