SinusPRO 550E Plus is a device designed to function as an uninterruptible power supply (UPS). It provides a 230 V AC output with a pure sine wave and features a built-in AVR stabilizer, ensuring voltage stability and making it suitable for powering electronic devices. The continuous maximum output power is 350 W, while the maximum peak power is 550 VA. You can connect an external 12 V battery to the device. In addition to standard AGM and gel batteries, the SinusPRO 550E Plus also supports LiFePO4 batteries. The maximum battery charging current is 10 A, and you can choose between 3 A, 5 A, or 10 A. The transfer time between mains and battery power is less than 4 ms.

350 W Uninterruptible Power Supply

The offered product is designed to function as an uninterruptible power supply (UPS), providing 350 W of continuous output power and 550 VA of peak (starting) power. It features a built-in AVR stabilizer and provides a stable 230 V AC output with a sinusoidal waveform. When connected to external batteries, it can protect connected devices against power outages or electrical system failures. The transfer time between mains and battery power is less than 4 ms.

Support for AGM, Gel, and LiFePO4 Batteries, Charging Current up to 10 A

The device supports standard AGM and gel batteries and additionally supports a newer type of battery - LiFePO4. SinusPRO features a built-in charger with a maximum charging current of 10 A. You can select one of three charging current settings: 3, 5, or 10 A. The connected batteries are protected against excessive discharge. The battery capacity and type should be selected according to the required backup time and the type of power supply.

Essential Protection Features

The SinusPRO 550E Plus includes all essential protection features and is protected against overload, short circuit, excessive temperature, high / low voltage, low battery voltage, excessive battery discharge, and reverse polarity. The power supply is equipped with active cooling, with fan speed adjusted according to the temperature and ambient conditions.
