Low Voltage Disconnect and Charging Discharging Protection 2 IN 1 40A DC 5V-60V Low Voltage Cutoff with LCD Display Low Voltage Protector Disconnect Switch Module Charging Discharging Protection Board

Renewable Energy Controllers

Buy on Amazon Find on eBay

It has a 2-in-1 charging mode (battery overcharge protection) and discharging mode (battery low voltage protection). The charging mode can be used for solar charging, and the battery automatically disconnects when it reaches the set voltage. The discharging mode can be used for battery low voltage protection.

Two low-power modes: automatic mode and manual mode. Manual mode consumes 0 power after the relay disconnects, and manual button reset is required after disconnection;

In automatic mode, the relay enters a low-power mode after disconnecting (LED turns off after 60s without any button action, and the LED resumes display when a button is pressed again). Standby current is 5mA (18V), and it automatically restarts when the voltage is restored.

The device has an internal flash storage module, so all settings can be restored after a power off.

Maximum 40A current, operating voltage from 5V to 60V.Supports a 99 seconds start delay, 99 seconds disconnect delay, and a 99:59:59 hours timer disconnect timer.
