3000 VA / 1800W Line-Interactive UPS, LCD display, battery 4*9Ah

• Uninterruptible Power Supply (UPS) 3000VA / 900W.
• Provides a continuous supply of 220V AC voltage in case of power failure or voltage instability.
• When the mains voltage is lost, it switches to operating mode within <0.01s.
• The inverter starts generating 220V AC electricity from the built-in 12 Volt battery.
• When the voltage becomes available from the mains, the device charges the battery itself.
• :: Microprocessor based digital control
• :: Input Voltage stabilization thanks to AVR
• :: Wide input voltage range
• :: Power-up self-test
• :: Cold Start - can turn on the UPS if there is no input voltage
• :: Automatic restart when power is restored
• :: Automatic mains phase tracking to ensure that the inverter output voltage has the same phase as the utility voltage, reducing transmission time and maximum overvoltage
• :: Intelligent battery management: battery temperature compensation to extend battery life
