About this Item

·       🌟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

Description

2Pcs XH-M609 DC 12V-36V Voltage Protection Module -Digital battery over-discharge protection switch is specially designed for 12-36V lithium and lead-acid battery.

Board Size:

57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H)

Example of setting instructions

Set lower than 12.5V to stop , higher than 14V to start:

Set the protection value:press " + " once to display the protection value , double- click " + " , the decimal point flashes , press+ , - to change the value at this time , and change it to12.5. If there is no operation for 3 seconds , the module will automatically save and exit the setting mode.

Set the return difference value:press " -" once to display the return difference value , double-click the " - " the decimal point flashes , press " + , - " to change the value at this time , and change it to 1.5. If there is no operation for 3 seconds , the module will automatically save and exit the setting mode.

Trouble Shooting

Trouble:Set this up to test a 3s li-on pack on a 10 watt LED the display lit for a couple minute then the module went dead never worked.

Reason:The module is only suitable for a single battery , not for battery pack.

Solution:Please connect with a single battery.

How to use:

The first time a new battery is used, the rated voltage value is close to the actual value, Judgment to stop the discharge voltage. A reasonable discharge voltage value can be obtained according to the general voltage calculation method of the battery. When the old battery is used, the actual voltage value and the rated voltage value are quite different, so you need to measure the stop voltage value in actual use.

Battery charging usually uses slow charging (the voltage and current of fast charging are relatively large, and the battery is easily damaged.) The charging voltage of slow charging is 1.2 times the rated voltage, and the charging current is adjusted to about 2/10 of the rated capacity current of the battery. For example: the charging voltage of a 6V 50Ah battery is about 7.2V, adjust the charging current to 10A.
