Traco Power TSP-BCM12, 35 mm, 110 mm, 110 mm, 510 g, 144 W, 12-14 V

This module provides a professional battery management system to charge and monitor an external lead-acid battery. Together with a power supply of the TSP series, a perfect DC-UPS system can be configured. The connected battery will be charged and held in charged mode by the power supply. In the event of a mains power failure the battery will supply the output power until the battery is discharged. As a consequence, the output voltage of the system is equivalent to the battery voltage. To avoid overcharging the battery, an external temperature sensor adjusts the battery voltage automatically to the required end of charge voltage. This can extend the battery life.
The battery is protected against deep discharge. Mains power and battery status are monitored regularly and failures indicated by corresponding LED’s and alarm outputs. The module also provides an external On/Off input to switch-off both, power supply and battery.
