40A & 60A Solid State Battery Guards


The PowerTector Battery Guard is a solid state battery device that will monitor the source voltage and disconnect the equipment from the battery if the voltage fails and disconnect the equipment from the battery if the voltage falls below a pre-determined level.


  • Input voltage range: 9-32Vdc (Automatic Referencing)
  • Output voltage: Equal to input voltage when operating (maximum of 100mV drop across terminals)
  • Transient over current rating (% of continuous value):
                      • 110% for 10s
                      • 200% for 1s
                      • 300% for < 0.5ms (On over current shutdown there is a retry every 30s)
  • Operating temperature: -25°C to +60°C to meet this specification table
  • Storage temperature: -25°C to +100°C
  • Ingress protection: IP65
  • Programming lead with 2.8mm blade connector provided
  • Output indicator Green LED for programming and output indication
  • Mounting method PT10/20 tie wrap to wiring (supplied) PT40/60/100/200 3off half inch No8 pozi pan head screws (supplied)
  • Safe area protection:
      • Over current – Limited by current sensing curcuit
      • Over heat – limited by temperature sensing circuit
      • Transients – Protected by filters and rugged component selection
      • Catastrophic protection – Set by external input fuse (set by application demands) and ground line fuse max 1A
