Постоянного тока в переменный Инвертор телекоммуникаций 1KVA 5KVA

High frequency telecommunication inverter 1KVA/5KVA: Descriptions: Along with the quick development of information network technology, Inverter / Power Inverter / Inverter Power Supply is a new DC to AC conversion power supply. The inverter power supply is widely used in the fields such as Telecom, Mobile, Unicom, Aviation and spaceflight, finance management, OA, industrial auto control, medical treatment and sanitation, military affairs, scientific research etc. Use the battery DC as input, after inverting, Inverter will outpu the pure sine wave AC. The output voltage and frequency is ultra-reliable and and work continully in long time. Inverter can eliminate the disadvantage such as power interrupt, un constant voltage, noise interfere and surge etc. At the same time, Inverter / Power Inverter / Inverter Power Supply can solve the limitation of short backup time of UPS. So Inverter / Power Inverter / Inverter Power Supply can ensure the continually and reliable working of electro-equipments. Main Characteristics TH series pure sine wave Inverter / Power Inverter / Inverter Power Supply is a new device which can invert the DC to AC, specially design for the communication system. Softwave protection and hardwave protection, high reliability. Perfect protection: input polarity reverse, input over/under voltage, over current, shortcircuit, over heat. Also the soft start function 3 layers composite filter and magnetism shielded whichand reduce the reflect noise voltage to the input port, perfect electromagnetism compatibility. Intelligent Fan Can connect with pure sensibility load (Should reduce voltage) Technical Parameter Model TH500TH1000TH2000TH3000TH5000Rated capacity VA500VA1000VA2000VA3000VA5000VARated output power (W)400W800W1600W2400W3500WDC InputRated input voltage (Vdc)48VRated input current (A)10255075125Shut down voltage range40V60VStart-up voltage range 46V57VReflect noise current≤10%AC input Allowed bypass voltage (Vac)220±15%Rated input current A2.34.59.113.622.7Bypass switch time (ms)≤5msAC output Rated output voltage and frequency 220Vac,50HzWaveformPure sine waveRated output current (A)1.83.67.210.816Output voltage precision (V)220±1.5%Output frequency precision (Hz)50Hz±0.1%Waveform distortion (THD)≤3%(liner load)Dynamic respond time5%(load 0←→100%)Power factor (PF)0.7/0.8Over loading capability120%,30Invert efficiency≥85%Operation environment Insulating intensity 1500Vac,1 minuteNoise (1m)≤40dBOperation temperature -25+50Humility090%, non condensingOperation altitude (m)≤1000Cooling modeForced wind coolingInverter status Mains supply is normal, invert normal, battery under voltage, output overloadingExternal dimension 19inch Rack (2U)482*88*250482*88*300482*88*380Weight 5Kg7 Kg8 Kg11 Kg13 KgStand-alone (W*H*D)/175*275*452222*328*452Weight /8 Kg9 Kg12 Kg15 KgColorWhite (grey)Protection functionInput under/over voltage, output overloading, short circuit, city power high-low voltage protectionOutput modeSocket or terminal blockterminal block
