SAMLEX BBM-1224i Battery Backup Switching Module 12V/24V with Battery Charger Function

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 Input voltage: 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 * Up to 8 A for 24 V battery * * NOTE: The unit is pre-set for charging current of up to 4 A for a 12 V battery and up to 8A for a 24 V battery. The charging current can be reduced to half the above values by disconnecting one of the two resistors R1, R2. Please see User Manual under Principle of Operation – Adjustment to reduce the values of maximum charging current to half. IMPORTANT: To prevent damage to your installation read user manual and follow the instructions. Check installation and use correct cables. Package: 1x Battery Backup Module. 1x User Manual in English, German, French and Dutch.
