VHM-003 Charging Control Module 12-24V Storage Charger Control Switch Protection Board

Product Introduction: Model: VHM-003 Input Voltage: 10-30V Display Precision: 0.1V Control Precision: 0.1V Output Type: direct output Voltage Tolerance: +/-0.1V Application Fields: 12-24V storage Size: 82*58*18mm Using Method: 1. Set Starting Voltage: in normal display voltage state, press the button will display start charging voltage; long press for 3s the digital tube will flash; you can start or stop button to set starting up charge voltage value 2. Set Stop Voltage: in normal display voltage state, press the button will display stoping charge voltage; long press the button for 3s the digital tube will flash; you can start or stop button to set stoping charge voltage value 3. Factory Reset: in on state press the start/stop button at the same time, digital tube will display 888; that represents factory reset settings Package Included: 1 x DC12V-24V Charge Control Protection Board


Key Operation: RUN: Press and hold 0.5S to enter the upper limit voltage interface. At this time, press the Run button, the upper limit voltage is +0.1, press the Stop button, and the upper limit voltage is -0.1.(Long press will increase/decrease continuously); STOP: Press and hold 0.5S to enter the lower limit voltage interface. Press Run button at this time, the upper limit voltage is +0.1, press the Stop button, the lower limit voltage is -0.1(long press will increase/decrease continuously). Product Features: 1. When the displayed voltage exceeds the upper limit voltage, the relay switch is turned off. When the display voltage is lower than the lower limit voltage, the relay switch is turned on. 2. This product has the function of saving the last setting data when is off.
