Alpha Technologies' Battery Disconnect Box Panel Assembly provides safe removal of the 24 or 48Vdc power system connection from the battery string via a robust 1200-amp contactor. The panel is therefore commonly used for emergency shut off of the batteries. Located on the front of the panel ia a pull and release locking toggle switch; provided to control the contactor for battery on-line or battery off-line.
Light emitting diodes (LED's) provide an indication of system status including battery on-line, battery off-line, contactor closure, power on, low voltage disconnect (LVD) remote 1 and 2, and fuse fail (if so equipped).
Located inside the panel, a key switch operates as a local lockout switch by controlling a relay circuit which disconnects the power from the onboard control circuit to the rest of the PCB. This will remove the power from the LEDs and the contactor coil. To ensure the safety of qualified personnel performing maintenance, the key switch should be placed in the OFF position and the key removed to ensure the batteries are off-line.
Up to two remote control inputs, provided by the user, can be used to open the contactor remotely and take the batteries off-line. This can be used to provide LVD functionality where the contactor is remotely controlled by a DC power system controller/monitor that automatically disconnects the battery after an extended power outage before damage to the battery occurs. Automatic reconnection will occur, after the power failure, initiated by the power system controller/monitor.
