NOTE: Due to the size constraints of the PCB board, this module features a miniaturized relay and thin circuit lines. Therefore, the current during actual use should not exceed 8A to prevent damage to the relay contacts. The maximum current is 10A when the voltage is below 12V, and it should be less than 8A when the voltage exceeds 12VSIMPLE OPERATION: To restore factory settings, power off the device, press and hold both buttons simultaneously, and then power on. The screen will display "888," indicating that the factory settings have been restored. The default protection value is set at 12V with a difference value of 2V. The difference value represents the voltage range between disconnecting and reconnecting the battery. User settings are retained in the event of an unexpected power loss, ensuring critical data is preserved and allowing seamless resumption of operationsSCOPE OF APPLICATION: This device is a voltage controller that employs a relay to switch the output on and off. The relay functions solely as a switch and does not alter the voltage. It is a protective switching module and does not include batteries. Compatible batteries include lead-acid, lithium-ion, and solar panel batteries. This module is not suitable for battery packsPARAMETERS: Board Size: 57 x 42 x 19 mm (2.24 x 1.65 x 0.75 inches) LxWxH; Input Voltage: DC 12-36V; Accuracy: 0.1V; Power Consumption:
