Details:

This product is a voltage controller, which turns on and off the output through relay, only acts as switch cannot change. Cermant digital low voltage protector 12v - 36v dc protection module with disconnect switch, ideal for solar panel lighting systems in campers:: input voltage : 12-36v,control accuracy: 0.1v, maximum amperage before breaker trips: 20a,power consumption: less than 1.5w,size: 2.24 1.65 0.75 inch. Instruction, press to view the disconnect voltage . Double the key and decimal point flashes.

The delay time ranges from to 010 minutes and is displayed as or 001 005. If the current exceeds 8a, relay contacts may be blown and cannot used normally.the maximum is 10a when voltage below 12v, less than 8a 12v. The reason may be that the module is only suitable for a single cell, not battery pack. Long press the key, and when led screen flashes, or - key to calibrate input voltage .

Package included:1pcs dc 12v-36v voltage protection module. Protect circuit:with accurate display function, when it is close to the minimum voltage , module can open or in time. Double press the - key, and when decimal point flashes, or key to set difference. When the decimal point flashes, press or - key to set disconnect voltage .

Press the key twice. The current should not be too large during actual use. Set the protection value: press key once to display value. When the output voltage reaches re connection value, load is reconnected after a delay of minutes.

Note: the relay size of this module is mini and the circuit lines are very thin. Hold down the - key, and then press or to set delay value t. The decimal point is not displayed. In addition, the settings can be maintained in event of a power outage.

Press - to view the difference. The solution is a single battery connection.
