1,MAIN FUNCTIONS: Voltage protection module provide over charge protection, over discharge protection, short circuit protection, and over current protection 2,VOLTAGE INFORMATION: The power supply voltage of the DC voltage protection module is DC 6V‑80V. The output voltage is equal to the power supply voltage 3,APPLICABLE SCENARIO: Voltage protection module is suitable for all applicable voltage range of industrial fields, such as electric two wheeled tricycle battery, automobile battery discharge protection, various battery overdischarge protection, solar energy, wind energy and other power supply system equipment input voltage protection 4,EASY CONFIGURATION: Easily adjust the protection values and save settings with the press of a button, set the stop or start voltage thresholds and hysteresis values for optimal battery protection 5,SCRATCH RESISTANT ABS: Battery voltage protection module adopt excellent ABS material, possess impact resistance, scratch resistance, and environmentally friendly Item Type: DC Voltage Protection Module Material: ABS Power Supply Voltage: DC6V-80V(output voltage is equal to power supply voltage, DC6V-80 maximum input DC80V, input voltage higher than 80V may be permanently damaged) How to Set: 1. Voltage Correction: For example, the input end is connected to 30V DC (only 30V this voltage), the two solder joints in the upper right corner of the display screen in the short circuit board (Calibration) for more than 1 second, the digital display CA.L flash to stop, release the two short circuit solder joints that the correction is completed. 2. Set ≦11V stop, ≧14V start, ≧15V stop. First Set The High Voltage Value: Press "HV" once to display the protection value, press and hold the value to blink, then press "and or -" to change the value to 15. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set The Cut Off Voltage Value: Press "and" once to display the current cut off voltage, hold down the value to blink, release the key, and then press "and or -" to change the value to 11. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set Back Difference: Press "-" once to display the current back difference voltage, hold down the value to blink, release the key, and then press "and or -" to change the value to 3. After no operation for 4 seconds, the module will automatically save and exit the setting mode. 3. Set the switch on in the range of 10.5V to 12V, other switch off (i.e. stop at low voltage ≦10.4V, stop at high voltage ≧12.1V). First Set The High Voltage Value: Press "HV" once to display the protection value, press and hold the value to blink, then press "and or -" to change the value to 12.1. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set The Cut Off Voltage Value: Press "and" once to display the current cut off voltage, hold down the value to blink, release the key, and then press "and or -" to change the value to 10.4. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set Back Difference: Press "-" once to display the current back difference voltage, hold down the value to blink, release the key, and then press "and or -" to change the value to 0.1. After no operation for 4 seconds, the module will automatically save and exit the setting mode. 4. Overvoltage Setting Range (HV Key): 6-80V-no limit (display - ), the factory default is no limit. In addition, the overvoltage voltage should be greater than the release voltage. If the setting cannot be "and or -", check whether the HV key setting value is appropriate. 1 x DC Voltage Protection Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
