The PWRshield module is a programmable LVD(Low Voltage Disconnect) and HVD(High Voltage Disconnect) power protect system. LVD function can protect the battery, prevent from over-discharging and damage the battery. HVD function can protect the load from being damaged due to excessive power supply voltage.
Programmable voltage setting for LVD and HVD(rocker switch set to AUTO). With emergency ON or OFF function, if you want switch output to be immediate and remain ON or OFF, you can set rocker switch to ON or OFF.
When the output is ON, the output status LED lights green. When the output is OFF, the output status LED lights red. When the input voltage is normal, the NORMAL LED(green) light is on. When the input voltage is lower than the normal value, the UNDER LED(red) light is on, and internal buzzer ALARM(slow-paced). When the input voltage is more than the normal value, the OVER LED(yellow) light is on, and internal buzzer ALARM(fast-paced). Three voltage status LEDs(NORMAL, UNDER and OVER) and buzzer are not affected by the state of the rocker switch. If you do not want to hear the annoying buzzer sound, you can open the upper cover and unplug a pin-jumper, however, we do not recommend you to do this because this "annoying voice" is a very useful reminder and warning.
NOTE:
Do not reverse input and output terminal, do not reverse connect battery/power supply polarity, otherwise it will damage battery or the module.
