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. Specification: Operating voltage: DC 6.5 ~ 30V Programmable HVD value: 14V/15V, 15V-16V, 16V/17V, 17V/18V. Programmable LVD value: 10V/11V, 10V/12V, 11V/12V, 11V/13V. Quiescent current(output off status): 2.5mA Quiescent current(output on status): 13mA Disconnect/Reconnect voltage tolerance: < 0.1V Max. output current: 40A (< 5 seconds) Max. continuous output current: 30A Voltage drop: 0.025V (at 10A) 0.070V (at 30A) MOSFETs: 30V 60A P-Channel, on status resistance < 0.002 ohm. Connectors: compatible 45A power pole connectors, Red is positive, Black is negative.Datasheet: https://m.media-amazon.com/images/I/91dFIuxkQ1L.pdf
