## Overview

The PWRshield LVD-HVD Power Guard Module is a cutting-edge power protection system featuring programmable low and high voltage disconnect capabilities. With a robust design based on microcontroller technology and low loss MOSFETs, it operates efficiently without the need for heatsinks, even at 30 Amps. The module comes with a complete installation package, ensuring you have everything needed for a seamless setup.

## Description

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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    quick delivery and perfect fit
  

*by E***Y on Reviewed in the United States on September 27, 2024*

works perfect to protect ham radios from over voltage

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Cut off the voltage can be set
  

*by M***M on Reviewed in the United States on February 3, 2021*

This unit is great and easy to operate and very inexpensive compared to losing a battery from running it totally dead. I really like that you can adjust the cut off voltage via dip switches. Also it won’t turn back on until the preset voltage so it gives your battery a little bit of time to charge. I designed my own double conversion UPS and this is a key component in that

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great Device ...
  

*by /***E on Reviewed in the United States on April 17, 2022*

This should be on any battery/power supply/radio type hook up for protection ... Works great ... I does not, however come with Anderson PowerPole connectors as advertised ... Otherwise, nice offering ...
