    Raritan's hybrid rack transfer switch system is the first in the world to offer both electromechanical relays and silicon-controlled rectifiers (SCRs) to overcome the limitations of a traditional automatic transfer switch (ATS).

SBR Series

PDI

PDI's SBR Series Static Automatic Transfer Switch supplies your critical loads with a choice between two available sources of electrical power.

The SBR continually monitors power quality and will automatically transfer to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms, the SBR represents the highest performance power switching solution available for the most critical applications.

WaveStar Series

PDI

Over 25 years of experience has allowed PDI to become the preferred supplier of 4ms transfer switches to a wide range of industries.

The new WaveStar communication package adds to this preference as it incorporates all of the features that the data center manager wants and needs in one compact package.

The PDI static switch supplies critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the WaveStar switch automatically transfers to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms and the industry's best communication package, the WaveStar represents the highest performance power switching solution available.

Intelligent Hybrid Rack Transfer Switch

Raritan's hybrid rack transfer switch system is the first in the world to offer both electromechanical relays and silicon-controlled rectifiers (SCRs) to overcome 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), more energy efficiently, and at a far more accessible price point. It is also the first in the world to offer inlet, outlet, and branch circuit level power metering; and outlet-level switching for better remote power control.

Raritan's rack transfer switch offers:

  • Current sampling at 4,800 times per second for load transfers within 4 to 8ms.
  • Oversized relays, rated at 48A, and SCRs, rated at 70A, even though the transfer switches are intended for 16A and 32A loads.
  • Relay contact air gap of 3.3mm vs. the 0.6mm gap used in most transfer switch relays on the market to prevent electric arcing.
  • Two single throw relays instead of one double throw relay (a single point of failure) to support reliable out-of-phase transfers.
  • Inlet, outlet, and branch circuit level metering.
  • Remote outlet switching.
