Product Description DC TO AC inverterIntroductionOur pure sine wave inverter is a dedicated power supply of a new generation of electric power and communication systems, we design and manufacture the inverter power supply according to the characteristics and requirements of the electric system, suitable for power system of power supply equipment high quality, high reliability requirements, are widely used in power system communication, carrier, monitoring, relay protection and emergency lighting. The power supply uses advanced sinusoidal pulse width modulation (SPWM) technology, the main circuit of Germany's Siemens IGBT module drive protection for Japan's Mitsubishi thick film circuit, with the advantages of high reliability, protection and full-featured, small waveform distortion, larger power and so on. production features(1) The main circuit adopts the United States INTEL microprocessor, Germany Siemens IGBT module, drive protection adopts Japan Mitsubishi movement, output partial adopts isolation transformer, safe and reliable(2) SPWM pulse width modulation technology, the output is inverter, pure sine wave of low distortion(3) Full-bridge circuit structure, applicable to any load(4) DC input uses state-of-the-art anti-filling noise suppression technology, the AC input of multiple filtering to eliminate the interference of the electricity grid, communication equipment and other common DC panel without disturbing each other(5) With a full range of power protection solutions and perfect self-detection and protection. DC input voltage is too low alarm, overload alarm, overheating alarm and short-circuit, the power will turn off the inverter output, troubleshooting, manually reset the power to work properly; Input under-voltage protection fault is cleared after the output will automatically resume(6) Compact circuit structure, high efficiency, strong function(7) Group-screen installation, elegant appearanceAdapt to the environment1. For desolate area like mountain, island, pasturing area, etc.2. For transportation system like beacon light, traffic light, street light, etc.3. For communication system: unattached operation microwave middle station, opticalcable maintenance station, etc.4. For photovoltaic power station, wind-solar power station, park charging station, family power house, factory power station, etc.5. For solar building: has good business future.6. For the new technology application project.off grid solar wind hybrid system:off grid wind power system:off grid solar power system:300KVA off grid three phase inverter technical parametersTypeNB480-300KSZDC inputInput rated voltage480 VDCInput rated current694 AInput DC voltage range400-620 VDCAC input(AC Bypass)Allow input voltage range220 VAC / 380 VAC / 400 VAC ± 15% VACInput rated current830A / 450A / 430ABypass transfer time≤100 ms (Can be customized ≤ 4ms version)AC outputRated capacity300KVAOutput rated power240KWOutput rated voltage and frequency220 VAC / 380 VAC / 400 VAC ,50Hz / 60HzOutput rated current830A / 450A / 430AOutput voltage accuracy220 VAC / 380 VAC / 400 VAC ± 1%Output frequency accuracy50Hz / 60Hz ±0.05%Waveform distortion (THD).(Linear load)≤3%Dynamic response time(Load 0←→100%)2msPower factor (PF)0.8Overload capacity110%,3 minutes,150%,5 secondsCrest factor (CF)3:1Inverter efficiency90%Working EnvironmentDielectric strength1500VAC,1minuteNoise (1m)≤50dBAmbient temperature-10oC~+50oCHumidity0~90%, No condensationAltitude<2000m(Higher than 2000m rated power should be reduced)Production functionInput reverse protection, input under-voltage protection, output overload protection, output short circuit protection, thermal protectionPure Sine WaveYesEquipped with copper transformerYesAC ChargerOptionalSolar ChargerOptionalGenerator portOptionalProduct Size(mm)1910*1160*1880mmProduct Weight(kg)1500kg400KVA(320KW) off grid three phase inverter data sheetTypeNB480-400KSZDC inputInput rated voltage480 VDCInput rated current926 AInput DC voltage range400-620 VDCAC input(AC Bypass)Allow input voltage range220 VAC / 380 VAC / 400 VAC ± 15% VACInput rated current1024A / 608A / 580ABypass transfer time≤100 ms (Can be customized ≤ 4ms version)AC outputRated capacity400KVAOutput rated power320KWOutput rated voltage and frequency220 VAC / 380 VAC / 400 VAC ,50Hz / 60HzOutput rated current1024A / 608A / 580AOutput voltage accuracy220 VAC / 380 VAC / 400 VAC ± 1%Output frequency accuracy50Hz / 60Hz ±0.05%Waveform distortion (THD).(Linear load)≤3%Dynamic response time(Load 0←→100%)2msPower factor (PF)0.8Overload capacity110%,3 minutes,150%,5 secondsCrest factor (CF)3:1Inverter efficiency90%Working EnvironmentDielectric strength1500VAC,1minuteNoise (1m)≤50dBAmbient temperature-10oC~+50oCHumidity0~90%,No condensationAltitude<2000m(Higher than 2000m rated power should be reduced)Equipped with copper transformerYes, 3 pcsPure Sine Wave YesAC BypassYes, when there is no enough battery power, will switch to GridAC ChargerAvailable, which is customized according to battery infoProduction functionInput reverse protection, input under-voltage protection, output overload protection, output short circuit protection, thermal protectionProduct Size1910*1160*1880mmProduct Weight1500-1800kg500KVA off grid three phase inverter data sheetTypeNB480-500KSZDC inputInput rated voltage480 VDCInput rated current1157 AInput DC voltage range400-620 VDCAC input(AC Bypass)Allow input voltage range220 VAC / 380 VAC / 400 VAC ± 15% VACInput rated current1280A / 760A / 725ABypass transfer time≤100 ms (Can be customized ≤ 4ms version)AC outputRated capacity500KVAOutput rated power400KWOutput rated voltage and frequency220 VAC / 380 VAC / 400 VAC ,50Hz / 60HzOutput rated current1280A / 760A / 725AOutput voltage accuracy220 VAC / 380 VAC / 400 VAC ± 1%Output frequency accuracy50Hz / 60Hz ±0.05%Waveform distortion (THD).(Linear load)≤3%Dynamic response time(Load 0←→100%)2msPower factor (PF)0.8Overload capacity110%,3 minutes,150%,5 secondsCrest factor (CF)3:1Inverter efficiency90%Working EnvironmentDielectric strength1500VAC,1minuteNoise (1m)≤50dBAmbient temperature-10oC~+50oCHumidity0~90%,No condensationAltitude<2000m(Higher than 2000m rated power should be reduced)Equipped with copper transformerYesPure Sine Wave YesAC ChargerOptionalSolar ChargerOptionalGenerator portOptionalProduction functionInput reverse protection, input under-voltage protection, output overload protection, output short circuit protection, thermal protectionProduct Size1910*1160*1880mmProduct Weight1500-1800kgFAQQ1: Are you a trading company or manufacturer?We are a factory.Q2: How long is your lead time?It depends on the solution you require but generally 30 days.
