Shenzhen Huayi special power inverters [Shenzhen Huayi special New Energy Technology] professional production of various inverter. Completely isolated inverter technology, no noise output sinusoidal AC voltage inverter unit uses advanced technology SPWM waveform pure, unique dynamic current loop control technology to ensure reliable operation of the inverter; strong overload capacity, able to withstand the full computer Load boot; power bypass switch can bypass overload. One: Introduction HET-frequency inverter series of pure sine wave inverter designed for power, communication system design, is a mains and battery power into a continuous, clean AC power conversion device for to computers and other electrical equipment can be used to provide continuous AC power mains to prepare for instability and power outages. Public power can also prevent various distortions, such as the supply voltage drops, surge, spikes and radio frequency interference. II: Frequency inverters work for DC voltage of 110V, 220V, or other DC voltage is 96V - 480V voltage occasions; AC voltage 220V single phase or three-phase 380V; 1: line work normal way when the mains power, the AC mains before after rectification, filtering, through an inverter reverse into pure AC power supply for the back-end load; when the grid mains abnormal or power inverter instantly convert into direct current supplied by the DC-screen or other device through the inverter can reverse into pure AC power supply for the back-end load; this conversion process time is 0, to ensure uninterrupted power supply; when grid electricity is restored to normal, The inverter then automatically switch to mains power supply; when the inverter solid barrier or internal wiring solid barrier, by static transfer switch, switch to automatic bypass, bypass mains powered directly from; this conversion time is very short, usually less than 4ms, to ensure uninterrupted power supply equipment; return to normal when the main circuit, the device will automatically switch to the main circuit power supply; 2: back-up work when mains power is normal, the AC mains through the static transfer switch, direct power to the load; when the grid mains abnormal or power inverter instantly convert direct current supplied by the DC-screen or other device through the inverter can reverse into pure AC power supply for the back-end load; this The conversion process is very short, about less than 4ms, to ensure uninterrupted power supply; when grid electricity is restored to normal, the inverter automatically switches to mains also direct power supply; 3: Pure inverter works just inverter DC converted to AC power for AC load or discharge a battery-activated three other occasions: Frequency inverter Features ● completely isolated inverter technology, no noise sinusoidal AC output voltage ● SPWM inverter unit uses advanced technology, waveform purity ● unique dynamic current loop control technology to ensure reliable operation of the inverter ● too strong load capacity, able to withstand the full load boot ● computer power bypass switch, overload can bypass ● have input over, under voltage, output over , under voltage, over temperature, short circuit protection ● inverter front panel LCD / LED display, four status at a glance: Frequency Inverter Specifications Power HET-1KVA-30KVA nominal DC input voltage 110VDC / 220VDC / Other When customizing voltage range 110VDC (94.5V-160V) / 220VDC (189V-280V) AC input Phase Single-phase / three-phase frequency 50Hz ± 5% voltage range of single-phase 220VAC ± 20% / three-phase 380VAC ± 20% of the inverter rated capacity of 800W-80KW output rated voltage single phase 220V / 380V three-phase single-phase voltage accuracy 220VAC ± 2% / three-phase 380VAC ± 2% when the frequency 50Hz ± 1% waveform distortion ≤ 3% 5% dynamic response (0% to 100% load) crest factor (CF) 3: 1 Power factor 0.8 Overload overload bypass jump 90% inverter efficiency (80% load) continuous operating time can be a long continuous operation alarm buzzer sounds an alarm and LED indicator Alarm switching time 0ms AC and DC inverter and bypass 5ms dielectric strength 1500 VAC, 1min (input and output) noise 45db (front 1 meter) Cooling fan forced air cooling
