Why Utility Companies use the PowerBack

  • Ultra-compact Power Restoration Device.
  • Provides same day temporary power restoration. 
  • Saves time and money. Now you can quickly restore power and schedule permanent repairs at a later date instead of having to make repairs immediately.
  • Designed for both overhead 120/240V and underground 120/240V 3-Wire systems.
  • Wheeled-Cart is Easy to Move. One person can transport the PowerBack to the job site. No crew or special truck is needed to transport the PowerBack.
  • Lightweight - Just half the weight of competitor products (see weights below)
  • No need to bridge or run shunts for residential customers who have lost one phase or the neutral to their home.
  • Improves public safety by avoiding the need to run temporary cables between customers when a phase is lost.
  • Increases customer satisfaction with faster service restoration.
  • Thermal Protected High Efficiency Toroidal Transformer- Located near the primary windings of the transformer is a 105C thermal protector switch wired directly to the Shunt-Trip solenoid in the Circuit breaker. Should the transformer over-heat due to overload or short-circuit, the circuit breaker will trip and shut the unit down.

How it works

The PowerBack provides a quick, convenient source of 240 volt power up to *20,000 VA from one phase and a good neutral or 120v service from two good phases (restoring neutral).

The PowerBack Restores Power to both homes and businesses.
