10-30V DC Voltage Monitoring DPST Relay Module, Low Voltage Disconnect LVD for 12V 18V 24V Battery, Load 80Amp/AC250V or 50Amp/DC30V
- To protect electronics from damaging low voltages and prevent a deep discharge of a battery during an extended power outage, the LVD module will automatically disconnect the battery when the voltage falls below the user adjustable cutoff voltage. When power is restored the Smart Switch will automatically reconnect the battery. thereby protecting the battery from total discharge (helping to prolong the life of the battery). Applications for Inverter, Solar systems, Alarm systems, UPS systems, Mobile systems, or any application where you need to protect the battery from total discharge.
- Operating voltage DC 10 to 30V. Switch maximum support current up to 80Amp(for AC) or 50Amp(for DC). Can support 12V, 18V or 24V battery system. Reconnect and disconnect voltage 10 ~ 30V you can set it arbitrarily (NOTE: reconnect voltage must be greater than the disconnect voltage). Quiescent current consumption is less than 2mA (It's the same whether it's ON or OFF)

With a rocker switch for override, can set to ON / AUTO / OFF function, if you want switch output to be immediate and remain ON or
OFF. (Note: When the battery voltage is lower than 9.5V, set the switch to ON state, the battery will not be forced on, this is to protect the battery and the module).
Red DIP switch, programmable voltage setting for Disconnect and Reconnect (rocker switch state must set to AUTO, otherwise the automatic function is invalid). For the setting value of the voltage, you can refer to the label on the side of the module. Please note that when setting the red DIP switch, the reconnect voltage must be greater than the disconnect voltage, otherwise the function will not work.
With three module output status LEDs, ON / ALARM / OFF, to help you intuitively understand the output status.
After power-on, the action will be delayed for 1 second to accurately judge the battery voltage and reduce the instantaneous discharge current of the battery. When the battery drops to the disconnect voltage value, there will be a delay of 120 seconds. During this period, the ALARM function will be used to remind you that if the battery voltage does not return to the normal voltage during this period, the output will be turned off. When the battery voltage returns to the reconnect voltage value for 5 seconds, the output will be reconnected.
