The work status indicator is useful for safe use.Widely used in all MCU control, industrial sector, PLC control, smart home control.Feature:Board size: 5.02cm x 7.03cmFixed hole diameter: 3mmFixed hole distance: 6.4 x 4.3cmMain chip: LM358Self power consumption:Static: self-consumption of about 12 mA (when the battery voltage is normal);Dynamic: Self-consumption of about 100 mA (when the battery is under voltage).Advantage:1. With sound and light alarm, there is no direct protection;2. Strong versatility;3. The board is allowed to pass 30A maximum, suitable for most 12V batteries;30A refers to the load current that the relay contacts are subjected to, not the current (capacity) of the battery.This module alarm is self-locking type:After 5 to 20 seconds after the battery is under voltage, the module automatically disconnects the output. When the battery voltage has risen above the set value, it will not be connected to the load again. It needs to be manually disconnected from the module before it can be restarted. The user can conveniently control the battery at the positive pole of the battery and the positive input of the module.Application:Suitable for 12V battery, when the battery voltage is normal, the "normal" indicator on the board lights up, the output is turned on; when the battery is over-discharged (below 10.4V), the board will automatically disconnect the battery output, "undervoltage" The indicator light is on and the buzzer is called to realize the sound and light alarm, so that the battery discharge state can be mastered to prevent the battery from being discharged too much and damaging the battery.Package includes:1 x Modulecontroller transmission module, Arduino DC motor module driver, module kit, relay module module boar
