Hybrid Rack Transfer Switch with

Outlet-Level Metering and Switching

Raritan’s hybrid rack transfer switches use electromechanical relays and silicon-con-

trolled rectiﬁers (SCRs) to transfer a load between two sources. The result is perfor-

mance 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.

• Current sampling at 4,800 times per second for load transfers within 4 to 8ms.

• The PX3TS-5000 series features outlet-level metering and switching.

• Only rack transfer switch with power metering, energy quality monitoring and support

for optional environmental sensors.

• Local and remote web-based monitoring, and control, and alarms.

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.

• Hybrid design eliminates out-of-phase transfer problems like arcing and provides more

deployment options since the feeds do not have to be the same phase.

• 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 relay contact surface area to handle larger currents.

• Offers surge protection, ﬁeld replaceable output short protection, redundant internal

power supplies and controllers.
