Raritan's hybrid rack transfer switch system is the first in the world to offer both electromechanical relays and silicon-controlled rectifiers (SCRs), overcoming the limitations of a traditional automatic transfer switch (ATS). It provides load transfer times that are comparable to that of a static transfer switch (STS) and increased energy efficiency.

Key features:

  • Current sampling at 4,800 times per second for load transfers within 4 to 8ms
  • Relays rated at 48A and SCRs rated at 70A
  • Relay contact air gap of 3.3mm vs. the 0.6mm gap used in most transfer switch relays
  • Two single throw relays instead of one double throw relay (a single point of failure) to support reliable out-of-phase transfers
  • Only rack transfer switch in the market proposing inlet, outlet and branch circuit level metering as well as remote outlet switching
