This module can be connected to a DC power supply to supply battery back-up power to your equipment in the event of an AC source power failure. On restoration of AC power the battery back-up module regulates output current and voltage to recharge the batteries.
This unit is a solid-state device which allows uninterrupted DC power in association with a power supply and a battery. The transfer of load between the power supply and the battery is instantaneous. It also keeps the battery charged by providing float charge.
Specifications:
- Connections: Automotive Spade-type Connectors

- 13.8 VDC for 12 V battery.
- 27.6 VDC for 24 V battery.
- Input current: Up to 35 A.
- Output Voltage:
- 0.5 V less than the input voltage (At 10 A)
- 13.5 VDC for input voltage of 14 VDC for 12 V battery.
- 27.1 VDC for input voltage of 27.6 VDC for 24 V battery.
- Output current to load:
- Up to 31 A for 12 V battery *
- Up to 27 A for 24 V battery *
- Charging current to battery:
- Up to 4 A for 12 V battery *
