360 Watt 2RU Rack Mount Battery Management System

The Model BMS-360-12 is a complete battery management system for installations which already have a primary power supply but are lacking battery backup. Smart Charging and battery protecting Low Voltage Disconnect maintain and prevent battery failures caused by over-charging and excessively deep discharging. Dual Schottky diodes provide smooth transfer to battery power and auto-revert to AC mains power that is seamless and glitch less.

The Smart Charger is designed to auto-charge and maintains Gelled electrolyte (Gel-Cell) and liquid electrolyte lead-acid 12 volt batteries up to 240 Amp Hour. The charger is a constant current monitoring charger for the charging and maintenance of fixed location UPS, emergency lighting systems, and telecommunications battery backup systems.

The charger is protected against over loading by deep discharge start circuitry with auto shut down due to over-voltage, over-temperature, short circuit and reverse polarity.

Switching mode circuit design provides high efficiency, compact size, cool operation, and high reliability.

The Model BMS-360-12 incorporates an automatic Low Voltage Disconnect that monitors battery voltage and disconnects the load when the battery voltage drops below 10.4 VDC. The LVD has been adjusted and calibrated at the factory for correct voltage disconnect and re-connect. No adjustment is required.

The LVD is pre-set to disconnect the load at 10.4 VDC. However, to prevent premature or false disconnect when the battery voltage drops below the 10.4 volt threshold a timer is started. If the battery recovers to above 10.4 volts, the timer resets and waits. The battery can and will recover if the system is a repeater or remote base station or similar equipment that has a varying demand that fluctuates from low to high current. The delay ensures the battery is not disconnected until necessary to prevent damage.

After the AC main power is restored and the battery is recharging, the LVD will reconnect the load when the battery voltage exceeds 12.5 volts.
