Raritan Rack Transfer Switches PX3TS-1147R - Power control unit (rack-mountable) - AC 120 V - Ethernet, RS-232, USB - input: NEMA L5-20 - output connectors: 8 - 1U
-
Patent-pending hybrid design
Raritan offers the first hybrid rack transfer switch combining electromechanical relays and silicon-controlled rectifiers (SCRs) for exceptional performance and reliability.
-
Blazing-fast transfer times
SCRs provide fast power transfer times at 4 to 8 ms, ensuring that your equipment continues to operate when power fails or fluctuates.
-
Designed for reliability
This pioneering rack transfer switch offers inlet surge protection, field replaceable output short protection, redundant internal power supplies and dual controllers.
-
Web-based remote power monitoring
Real-time remote power quality monitoring with user define-able thresholds and alerts for voltage and frequency. It includes AC waveform of last transfer and metering of inlet power loads.
-
Break-before-make
Built-in sensors ensure break-before-make power transfers from the first power source to the second and from the SCR to the electromechanical relay.
-
Out-of-phase transfers
Uses two single throw relays instead of one double throw relay (a single point of failure) to support reliable transfers regardless of power phase.
-
Eliminates relay welding
It uses SCRs and oversized relays, with an air gap of 3.3 mm vs. the 0.6 mm gap as used in most transfer switch relays, to prevent arcing due to power surges.
-
Industry's most flexible USB port
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.
-
Remote management capabilities
Threshold alerting and status updates via GSM text, email, and syslog.
-
Energy metering and power quality monitoring
Make informed capacity planning decisions, efficiently utilize power resources, and monitor power fluctuations that may disrupt equipment.
-
DCIM monitoring integration
Seamlessly integrates with Raritan's Power IQ DCIM Monitoring solution for effective data center power infrastructure management.
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 16 ms, and often fail as a result of electrical arcing that welds contacts together. Static transfer switches (STS) offer very fast transfers of 4 to 6 ms, 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.
