Product Details
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
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 8ms, 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. Includes AC waveform of last transfer And metering of Power loads.
Real-Time Power Metering
Monitor Power utilization at the inlet, outlet, or branch circuit level to prevent tripped breakers, uncover hidden capacity, And use resources efficiently.
Remote Power Control
Reboot hung servers or keep outlets off to prevent unauthorized access, ensure proper provisioning, And avoid tripped breakers.
Additional Features
Break-Before-Make
Built-in sensors detect failed Power feeds And ensure break-before-make Power transfer from one Power source to another within 4 to 8ms.
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
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.
- Load transfer times 4-8ms
- Reliable transfer between sources regardless of phase
- Over-sized relays (rated 48A) And SCRs (rated 70A)
- Eliminates electrical arcing that leads to transfer relay failure
- 3.3mm vs. typical 0.6mm contact air gap to prevent arcing due to surges
- Inlet surge protection And field replace-able, fast-blow fuses For short circuit protection
- Inlet or outlet-level metering And switching, with Power quality monitoring
- User configurable thresholds For Power quality
- Ethernet, Modbus, And SNMP networking
- USB ports For Wi-Fi, camera, tablet, And cascading
