Static Switch
 

The Automatic Static Switch product line is a micro-controller driven state - of - art switch between the AC mains and the inverter to provide uninterruptible AC power. After an extremely quick detection of mains fault, the static switch transfers the load almost without cut off to the redundant AC line.

 A communication and synchronization bus is responsible for the system performance and the Inverters are synchronized to the public AC mains.

Super Fast (1/4 cycle) SCR Based Static Transfer Switch for high availability mission.

Critical transfers for all phase angle differences between sources.

Features:
  • ON LINE or OFF LINE mode selection.
  • High performance AC line quality monitoring.
  • Quick detection of AC faults.
  • Configurable switching criteria.
  • Load transfer up to 20 kVA.
  • Synchronization of the UPS and Mains.
  • Convection cooled.
  • Compact and light.
  • Power connectors on the bottom with circuit breakers.

Applications:

  • Critical Data Centers
  • Telecommunications Sites
  • Air Traffic Control Sites
  • Petrochemical Plants
  • Semiconductor Fab Plants Controls
  • Critical Industrial Controls
