  • Description
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.

Features：
1, The PWRshield module is a programmable LVD(Low Voltage Disconnect) and HVD(High Voltage Disconnect) power protect system. 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.
2, Design based on microcontroller and low loss MOSFETs (on status resistance < 0.002 ohm), you do not have to add heatsinks even for 30 Amps of continuous working current.
3, Standard 30 Amps Power pole connectors.
4, High quality aluminum enclosure, thickness 1.5mm/0.06".
5, Attachment includes: 
        2x black power pole housings.
        2x red power pole housings.
        2x PVC cover flame retardant sleeve.
        4x silver plated copper 30A 14-12AWG power pole contacts.
