Battery Low Voltage Disconnect
In order to prevent damage to the battery due to deep discharge, the DC power system has hardware support for a battery Low Voltage Disconnect (LVD). A battery LVD has the loads attached to the rectifiers and the battery is disconnected from the system. The MX06 provides control for a motorized circuit breaker on the –48 V battery string. This motorized circuit breaker is mounted on the back of the MX06. Figure 10 shows the power, control, and monitoring connections. The controller will turn the motorized breaker off in a low voltage condition to protect the battery. It can also be turned off manually as you would a non-motorized breaker. In the event of an over-current situation the breaker will trip like a normal breaker.
