Description:
Shorter Depth unit of Raritans innovative rack transfer switch designed for performance and reliability. Shorter Depth unit 420mm The Raritan hybrid rack transfer switches uses electromechanical relays and silicon-controlled rectifiers (SCRs) to transfer a load between two sources. The result is performance and reliability that exceeds that of standard automatic transfer switches (ATS) and at a lower price point than static transfer switches (STS) Industry leading performance: Uses SCRs to provide STS-like transfer times and eliminate electrical arcing and welding of relays; hybrid relay plus SCR-design allows hand off of the transferred load to a relay, making it power efficient and producing less heat. Fast detection time ensures failed power feeds are detected and the loads transfered within 4 to 8ms. Only rack transfer switch with power metering, energy quality monitoring and support for optional environmental sensors. Local and remote web-based monitoring and control Designed with maximum reliability in mind: Oversized relays, rated at 48A, and SCRs, rated at 70A, even though the transfer switches are intended for 16A and 32A loads. Prevents transfers of output short circuits which could lead to failure of the second power feed. Uses two single throw relays instead of one double throw relay (a single point of failure) to support reliable out-of-phase transfers. Uses relays with an air gap of 3.3mm vs. the 0.6mm gap used in most transfer switch relays on the market. Prevents arcing due to surges. Offers a 30% larger surface area between the relay contacts to handle larger currents. Offers surge protection, field replaceable output short protection, redundant internal power supplies and redundant controllers. Silicon-Controlled Rectifier Switches (STS): - Offer very fast transfer times (normally 4 to 6ms), but are over five and a half times more expensive than electromechanical switches. - Draw significantly more energy than electromechanical relays and produce more heat thereby consuming cooling resources. - Are less energy efficient requiring forced cooling and lower maximum operating temperatures. - Reduce the energy efficiency of the rack.
