Power Isolator

Positron is pleased to announce the Positron Power Isolator, a system for delivering high-voltage isolated 100 Watts @ 48 Vdc up to 2000 feet from the substation power source.

It accepts an input voltage of nominal 130 Vdc or 120 Vac and provides a regulated floating output of 100 Watts @ 48 Vdc, with an isolation rating of 50 kVrms (70 kV peak).


  • Power a GPON Fiber-Fiber Junction (FFJ)
  • Power a Copper Fiber Junction (CFJ) inside or outside of the substation Zone of Influence
  • Power the substation’s wireless receiver in the switchyard
  • Power surveillance cameras
  • Power Alarm Systems
