Charge Protection Board Auto ON/OFF Charging Controller Module 12V 24V 48V Batteries
- The 1% high precision divider resistor makes voltage measurement more accurately.
- The protection board supports power supply surge protection; when power on, power supply has a instantaneous high voltage, and can reduce instantaneous high voltage to protect circuit.
- Save parameters when power failure to avoid repeated settings.
- Voltage precision and resolution is 0.1 V, and has calibration function.
- Lower digital tube display brightness, energy saving and protect your eyes.
