Description:

【NOTE】This product is a voltage controller, which turns on and off the output through a relay, which only acts as a switch and cannot change the voltage. It's a protection switch module, not included batteries itself. In addition, if you have any questions in use, please contact us at the first time.
【OVER DISCHARGE PROTECTION】You can freely set the discharging mode and set parameters. For example, when the battery voltage reaches the set voltage, the module will automatically disconnect to avoid battery over-discharging and prolong battery life.
【MEMORY FUNCTION】With power-off protection, it will save your setting when power off suddenly.
【DELAY TURN-ON】That means, after a disconnect, the interval between turning on again. The time range that can be set is 0-999 seconds
【PARAMETER】Board Size: 57 x 42 x 19mm/2.24 x 1.65 x 0.75inch(L*W*H); Input Voltage: DC 12-36V; Accuracy: 0.1V; Power Consumption: <1.5W; Maximum Amperage before Breaker Trips: 20A

low Voltage Cutoff 12V Disconnect Switch

protect battery and prolong battery life

Compatible with 12-36V lithium and lead-acid battery. This is a relay module, not included any battery. Only suitable for a single battery, not for a battery pack.
When the battery voltage reaches the set disconnect voltage, the module will disconnect load automatically to prevent the battery from over-discharging so as to prolong the battery lifetime.
Support delay 0-10 minutes to reconnect
Reliable and easy to set up

Input Voltage Range: DC12-36V
Control Accuracy: 0.1V
Compatible Battery: lead acid, lithium ion battery, solar panel battery
Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H)
Packed in anti-static bag

Instructions

Double press the “+” button, and when the decimal point is flashing, press the “+” or “-" button to set the disconnect voltage.
Double press the “-" button, and when the decimal point is flashing, press the “+” or “-" button to set the difference value.
Long press the “+” button, and when the LED screen is flashing, press the “+” or “-" button to calibrate the input voltage.
Long press the “-" button, and then press the “+” or “-" button to set the delay value T. That is to say, when the output voltage reaches the reconnect value, it will delay T minutes, the load reconnects. The delay time range from 000 to 010 minutes, and it displays like: 000 or 001 or 005 or 010. Note that no decimal point is displayed at this time.
Press the “+” button to view disconnect voltage.
Press the “-" button to view difference value.

*What is the "difference value"?

The value between the disconnect voltage and the reconnect voltage. That is to say, difference value = reconnect voltage - disconnect voltage

For example

1. How to set if I want it to stop outputting when the voltage is lower than 11V and start when the voltage is over 11.6V?

Long press “+” and the LED starts flashing, press the “+” or “-" button to set the value as 11V. After the flashing stops, long press “-" and when the LED is flashing, press the “+” or “-" button to set the difference value as 0.6V.

2. How to set if I want it to stop outputting when the battery voltage is lower than 12.5V and when it is over 14.8V, it starts outputting after 2 minutes?

Double press “+” button to set it as 12.5 and then double press “-" button to set the difference value as 2.3 (because 14.8V-12.5=2.3V). And then press and hold on the “-" button, set T=2.

Why it doesn’t has output when I first connect it?

For example, if the disconnect volt is 9V and the difference value is 5V, then:

When first connected, if the battery is lower than 9V, there will be no output;
When first connected, if the battery is higher than 9V but lower than 14V (9+5), there will be no output;
When first connected, if the battery is higher than 14V(the reconnect voltage), there will be output;
During use, the module will be disconnected when the voltage drops to 9V, and will be automatically reconnected when the battery is charged to 14V.

Something You Need to Know...

This product works great to cut off the voltage when a battery discharges to a set level. It stops the output/load but you can NOT leave a battery hooked up to this product. This voltage cutoff (this product) stays on and will continue to drain the battery as this product (understandably) needs electricity to operate. True, this product will drain the battery much more slowly than your load was probably draining the battery, but make no mistake, this product consumes electricity after disconnecting the load and gets that electricity from your battery, eventually draining it.
It can only work with a single battery, not work well with the battery in parallel(battery pack). Most big batteries are made of many small batteries inside, such as Mil-waukee/ De-walt battery. So we don't recommend you to use it with these batteries.

Package included:

1pcs Digital Low Voltage Protector Protection Module
