- Uninterruptible Power Supply (UPS) 650VA / 390W.
- 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

Как рассчитать время работы Источника Бесперебойного Питания (ИБП) при работе только от аккумулятора при отключении электроэнергии?
Формула расчета: T = C * V * η/P, где
- T - Расчетное время работы в часах (ч)
- C - Общая емкость батареи в ампер-часах (Ач)
- V - напряжение батареи в вольтах (В)
- η - КПД ИБП, который обычно используется в расчетах 0,92
- P - средняя мощность в ваттах подключенных устройств (Вт)
Пример расчета при средней мощности подключенных устройств 100 Вт:
0,77 = 7 * 12 * 0,92 / 100, где 0,77 ч — это 46 минут
При средней мощности подключаемых устройств 200 Вт время работы составит 23 минуты.
При средней мощности подключаемых устройств 300Вт время работы составит 15 минут.
