Raritan’s innovative hybrid rack transfer system provides industry leading performance and maximum reliability. Traditional automatic transfer switches (ATS) suffer from longer transfer times of 8 to 16ms, and often fail as a result of electrical arcing that welds contacts together. Static transfer switches (STS) offer very fast transfers of 4 to 6ms, but are over five and half times more expensive than ATS, draw far more energy and produce excess heat.
Raritan’s hybrid transfer switch cleverly uses both electromechanical relays and silicon-controlled rectifiers (SCRs) to maximize the positive and minimize the negative characteristics of each.
Raritan offers the first hybrid rack transfer switch combining electromechanical relays and silicon-controlled rectifiers (SCRs) for exceptional performance and reliability.
SCRs provide fast power transfer times at 4 to 8ms, ensuring that your equipment continues to operate when power fails or fluctuates.
This pioneering rack transfer switch offers inlet surge protection, field replaceable output short protection, redundant internal power supplies and dual controllers
Real-time remote power quality monitoring with user define-able thresholds and alerts for voltage and frequency. Includes AC waveform of last transfer and metering of inlet power loads.
Built-in sensors detect failed power feeds and ensure break-before-make power transfer from one power source to another within 4 to 8ms.
Uses two single throw relays instead of one double throw relay (a single point of failure) to support reliable transfers regardless of power phase.
Uses SCRs and oversized relays, with an air gap of 3.3mm vs. the 0.6mm gap as used in most transfer switch relays, to prevent arcing due to power surges.
Optional ports for plug-and-play environmental sensors that allow you to monitor critical environmental conditions.
The transfer switch comes equipped with front and back USB ports to support Wi-Fi networking, cascading, webcams, quick setup, and tablet access and control.
Threshold alerting and status updates via GSM text, email, and syslog. An intuitive GUI, SNMP, Modbus, TCP/IP, JSON-RPC for scripting, IPv4/IPv6.
Make informed capacity planning decisions, efficiently utilize power resources, and monitor power fluctuations that may disrupt equipment.
Runs up to 60°C(UL) and 50°C(CE) environment at 85% relative humidity.
Seamlessly integrates with Raritan’s Power IQ® DCIM Monitoring solution for effective data center power infrastructure management.
