Battery Backup System is a system which charges the battery with received energy from mains and then delivers to DC 48V and/or AC 220V output. When mains is off, system feeds the field for a while according to capacity of batteries.
- Charges batteries according to their capacities.
- Separates from electricity when battery voltage is on a particular level./s
- Keeps trickle charging when battery is fully charged.
- Has various alarms like no mains, low voltage, high temperature and door open alarms.

The switching product shown is developed for use in the battery backup panel of outdoor base stations. The system operates by automatically switching the batteries based on the power line conditions.
If the external battery power fails, the system runs on the internal batteries. Otherwise, it supplies power from the internal source to the system and then switches to charge the batteries when conditions allow.

The backups are manufactured by revaluating your excess rectifiers at the desired power and battery capacity — with or without inverter.
In this Battery Backup system, there are three units of 1000W rectifier used in 1U sized Eltek.
The 3 kW Mean Well Inverter has a special circuit which resets the inverter and sends a fault alarm from the UPS output in case of any overload protection.
