400va 650vva 1000va 1200va 3000va UPS with AVR Backup UPS Offline UPS

400VA to 3000VA Offline UPS with AVR Technology Backup UPS For Office and PCApplication:       The off-line UPS is the standby status with batteries being charged in normal AC time.When the power supply unexpectedly shuts down,the built-in inverter will in no time convert the battery output into AC to keep stable power supply.The UPS is generally considered high mostly used in comparably stable environment with a small fluctuation of utility power and lower requirement of power supply quality.      The UPS now is widely usedin protection of PC in govermment offices,education institues ans SMEs.Key Features:1.        Advanced CPU control and intelligent battery management.2.        With Boost and Buck AVR and the full bridge inverter technology to obtain stable and wide input voltage and frequency range.3.        Off mode charging and auto restart while AC recovery.4.        Battery mode no-load automatic shutdown after two minutes.5.        IEC cables connect with PC can match with various generators.6.        Support RS232 and USB communicationmonitoring accompanied with Modem/Line Surge Protection: RJ11/RJ12/RJ45.7.        Overload/ Over charge/ Short-circuit/ protection/Low battery automatic alarm.Specifications:Model N400N500N650N800N1000N1200N1500Nominal Capacity400VA/240W500VA/300W650VA/390W800VA/480W1000VA/600W1200VA/720W1500VA/900WInputVoltage Range140-290VAC±5v or 70-145VAC±5vFrequency50/60Hz(40-70Hz)OutputVoltage Range220/230VAC or 110/120VAC ±10%(AC mode)      220/230VAC or 110/120VAC ±5% (Battery mode)Frequency50Hz/60Hz ±5%Output WaveformSine Wave (AC Mode), Square Wave (Battery mode)Transfer time< 10msBatteryTypeSealed free maintenance lead acid batteryCapacity12V,4AH *1PCS12V,7AH *1PCS12V,7AH *1PCS12V,9AH *1PCS12V,7AH *2PCS12V,9AH *2PCS12V,9AH *2PCSRecharge Time8 hrs to 90% of capacity full load dischargeProtectionAuto protectBack-up time(at a PC load with 15"monitor)8 minutes15 minutes15 minutes20 minutes28 minutes35 minutes35 minutesFunctionAuto voltage output on AC mode, Auto shutoff if short circuit or overloadDB-9 port,communication softwareOptional RS232, RJ11, RJ45, USB ProtectionAC modeFuseShort circuitACFuseInvert modeAuto protectAlarmAlarmBattery dischargeAlarm beeps every four secondsLow battery voltageAlarm beeps every secondOverloadAlarm beeps continuouslyIndicator lightAuto adjustGreen lighting: AC modeBattery DischargeRed lighting: Battery modeEnvironmentOperating temperature0ºC~40ºCOperating Humidity0-90% non-condensingNoise
