PX3 Intelligent Rack PDU

3. Raritan’s PX® intelligent rack PDU series offers
more than just power distribution -- it’s a launch
pad for real-time remote power monitoring,
environmental sensors, data center infrastructure
management, and so much more.

4. Reason #1: Energy Efficient Latching Relays
Relays Require Less Power and Produce Less Heat
Latching bistable relays only require power to switch from one state to another
so PDUs consume 67% less energy, produce less heat, and return to pre-outage
state with patent-pending outlet sequencing technology that minimize inrush
current.

5. Reason #2: Patent-Pending Outlet Sequencing
User Configurable Power on Sequencing
• Last known state or outlet sequenced power on.
Last Known State
• Relay state remains the same as before power loss.
Latching Relay Behavior
• Latching Relays do NOT require power to keep their contacts closed.

6. Reason #3: High Quality Standards
Intelligent Replaceable Controller
• Flush mount controller with industrial grade reliability, configurable firmware,
and hot swap capability.
• In the unlikely event of a malfunction you’ll be able to replace it without
having to interrupt any business critical services!

7. Reason #3: High Quality Standards
Brilliant Color Display
• Highest on-board resolution in the industry at 220x176 that’s easy to read
and navigate. A built-in accelerometer enables the display to change
orientation automatically facilitating installation. Controls are simple and
intuitive.

8. Reason #4: Best-in-Class Design
kWh Metering
• New metering chip and power metering firmware for greater accuracy.
Accuracy over the entire range of measurement.
• Accurate kWh metering allows you to measure actual power usage for
accurate customer or department charge-back billing.
• The data can be used to encourage energy efficient behavior among users,
establish power consumption baselines, and analyze the effect of efficiency
initiatives.
+/-1%

9. Reason #4: Best-in-Class Design
Low Profile Flush Mount Circuit Breakers
• Prevents blocking rack space and eliminates doghouse allowing usage along
length of PDU.
• Circuit breakers eliminate the need to stock fuses, have licensed electricians
change fuses, and the possibility of installing an incorrect fuse compromising
safety and voiding product warranties.

10. Reason #4: Best-in-Class Design
One More Magical USB Port
• Customers love our USB capabilities so much that we added another port.
• Multiple USB ports allow for Wi-Fi networking, cascading (daisy chaining),
quick setup, firmware upgrades, security cams, and a remote display. Ports
can also be disabled for security.
• Customers eliminate network infrastructure costs, save time on deployment
and upgrades, and add an additional layer of physical security.

11. Reason #5: It Solves Practical Problems
Custom Mechanical Design
• We use 3D modeling tools to create the perfect fit for your rack with space-saving
Zero U, 1U, 2U, and 3U form factors that provide unobstructed access
to your rack for faster service calls, equipment changes, and deploying newly
provisioned equipment.

12. Reason #5: It Solves Practical Problems
We Support Dense, High Power Racks
• We offer a broad range of 400V three-phase high power models that support
up to 55kW per rack PDU. Running higher voltages at lower currents means
smaller and fewer cables, which use less copper, weigh less, occupy less
space, and cost less.

13. Reason #5: It Solves Practical Problems
We Support Dense, High Power Racks
• We support a maximum operating temperature of up to 60°C / 140°F for
reliable performance in dense high-heat environments so you can rest
assured that they’ll continue to operate reliably in the harshest of conditions.

14. Reason #5: It Solves Practical Problems
Quick Setup and Upgrades
• Use ordinary USB sticks to configure hundreds of PDU’s in mere minutes.
Save big on deployment time and costs.

15. Reason #5: It Solves Practical Problems
Full Color Chassis
• Available in ten colors that help reduce errors, and make it easier to identify
power feeds, and troubleshoot, thereby lowering the risk and duration of
unplanned downtime.

16. Reason #5: It Solves Practical Problems
Residual Current Monitoring
• Reduces the risk of electric shock by measuring current flowing in the ground
wire. These residual currents will generate a system alert and keep technicians
working on racks safe from harm.

18. BONUS Introducing Raritan’s
Hybrid Rack Transfer Switch

19. Raritan’s hybrid rack transfer switches use
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) at a lower price point than static
transfer switches (STS).

20. Patent-Pending Hybrid Design
• 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
transferred 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, and alarms.

21. 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.

22. Data Center Applications
Most common applications are
• Ethernet switch, firewall, or router
• Servers with single power supplies
Expected maximum load
• Typically <8A
• Maximum <16A
