Static Transfer Switch (STS)

Call For Pricing

 

The i-power single phase static transfer switches (STS) transfer the power supply between independent single phase current power sources. In the event of an interruption or abnormal conditions in one source feeder the critical load will be transferred to the second power source without interruption of power to the connected load. The i-power STS provide an extremely fast load transfer, typically 1/4 of a cycle. This high speed load transfer guarantees the uninterrupted operation for even the most sensitive electronic equipment.

Product Highlights:

  • Source-A, Source-B, Source A/B
  • USB/RS 485 serial port interface (Optional).
  • Auto restart (when mains power is restored, after discharge of the batteries).
  • All devices are fully tested and verified for maximum performance.
