Rack-Mount Static Transfer Switch

Highly reliable power redundancy for mission critical IT equipment

The Rack-Mount Static Transfer Switch (rSTS) safeguards the uninterrupted operation of mission critical IT equipment. Powered by two independent power sources, the rSTS rapidly switches from one source to the other automatically when the power supply used to power its connected load fails. For datacenter applications the rSTS allows power drop risk to be shared or distributed to each rack to prevent power loss for the whole system. The rSTS offers an efficient and reliable switch that supports the high redundancy requirements of mission critical power systems.

Metered rPDU

Availability 

  1. Adopts SCR design instead of a relay as a switching device to increase reliability and handle high inrush current
  2. Supports power redundant configurations for high reliability

Convenience  

  1. Rack-mounted type with 1U size for easy installation and relocation
  2. Built-in SNMP for remote management
  3. LED indicators show power flow
  4. Self-test function

Safety

  1. Break before make prevents short circuits between two sources
