Product Details

🌟Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H), Input Voltage Range: DC12-36V, Control Accuracy: 0.1V, Power Consumption: <1.5W, Instantaneous maximum current before circuit breaker trip: 20A.
🌟Note:Due to the limitation of the size of the PCB board, the relay size of this module is mini and the circuit lines are very thin. The current should not be too large during actual use. If the current exceeds 8A, the relay contacts may be blown and cannot be used normally.The maximum current is 10A when the voltage is below 12V, and less than 8A when the voltage exceeds 12V
🌟Programmable battery low voltage disconnect switch for DC12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.Compatible Battery: lead acid, lithium ion battery, solar panel battery.Not suitable for battery packs.
🌟On-board momentary push button to set the low voltage disconnect parameter and 3 digit red LED display the parameter easy to operation.When the battery voltage reach the setting values, the module will disconnect load automatically to aviod the battery from over discharging to prolong the battery lifetime. (Note:The relay does not contain a power cut-off switch,remember to cut off the power supply after disconnection, otherwise the module will continue to use the battery until the voltage is 0.)
🌟Reset:When the power is off, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings are restored.The factory-set protection value: 12V, difference value: 2V.Difference Value"is the value between the battery voltage to disconnect and the battery voltage to reconnect.
🌟Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off

Best Review

Customers find the voltage protection module works well and consider it a very inexpensive unit. The accuracy and ease of use receive mixed feedback - while some find it accurate and easy to use, others note it's not super accurate and lacks clear instructions. Moreover, customers report issues with battery drain as the circuit continuously drains power, and the light level feature turns off at the set voltage.AI Generated from the text of customer reviews
