General Description

Low Voltage Disconnect (if applicable)

APS3-059, APS3-061 and APS6-059 models are equipped with a Low Voltage Disconnect (LVD) module.

The LVD disconnects the batteries at the LVD disconnect voltage to prevent damage to the batteries due to excessive deep discharge. After the batteries are disconnected, they recover to their open-circuit voltage. The LVD reconnects the batteries automatically after the AC supply is restored. After the batteries are reconnected, the power system recharges the batteries and powers the loads.

Both the LVD disconnect and reconnect voltages are configurable. The default LVD disconnect voltage is set to 44 V and the reconnect voltage to 48 V. This hysteresis band ensures that the open-circuit recovery of the discharged batteries does not rise above the LVD reconnect voltage.
