Some Considerations
 The trend for bus bar power
distribution to the IT rack is growing
globally
 UEC themselves have seen an
significant increase in demand for
Starline over the last 7 years largely
due to the data centre industry
 Since 2008 Universal Electric
Corporation have manufactured
nearly 500 miles of busbar and ½
million plug in’s.

80% of UEC business is in the mission critical sector
Data Centre Main Challenges
 Continued optimisation of power consumption
 Enabling kW ranges per rack from 2kW up to 40kW
 Enabling Single and Three Phase Loads
 Meeting the power flexibility demands of the business
 Maximising revenue potential
 Maintaining uptime while the business grows
 Maintaining continuity including spares and design
Overcoming these challenges with
Starline
 Circuit identification made easy
 Improve rack power distribution flexibility
 Improve speed of deployment
 Reduce circuit lead-time & circuit addition costs
 Improve MAC management
 Improves cooling efficiency (by reducing cable air dams)
 Reduces risk by
 reducing the length of time personnel spend in the live IT
space
 eliminating floor tile removal
Why use Bus Bar?
 Bus bar is not a new technology BUT how we deploy and
customise supporting products is evolving
 Rack revenues are being driven down due to the large amount
of competition
 Demand for modular space is growing - very well suited to
bus bar applications
 Maximise the space available i.e. utilisation is desirable so:
 Flexibility is key
 Speed of deployment can be essential
 Pro-active & Reactive – being prepared applies to everyone
Why use Starline?
•

•
•
•
Customisation – product flexibility to meet demand
UEC will never discontinue a product once sold –
continuity of spares and design
Open channel design – maximise the bar space
Starline does not use bolted or torqued joints - less risk +
lower TCO
Designed to operate live, no small print caveats – uptime
maintained at all times
Easiest plug-in installation in the market - very quick to
install

Operational Considerations

come
IT refresh rates are likely to increase as technology moves
quickly
Power densities are likely to increase year on year
Managing many contractors and staff for upgrade projects is
hard work and a timely process
Keeping personnel out of the live DC space is desirable from
a risk point of view - minimise time spent in the IT space

The Plug-in Addition Process
 Plug-ins are tested and approved at the factory before
shipping
 The DC operator provides on site plug-in verification
i.e. phasing prior to live installation
 Live plug-in installation is done with load circuit
breaker open to minimise risk
 Starline live busbar plug-in installation is as safe as an
installation of cable into a live PDU

New Projects with Customisation
 Problem: Limited head room and limited bar length
 Brief: Design a system to meet the customers current and
future requirements – increase revenue potential
 Plan: Design, produce prototypes and manufacture the
necessary equipment to meet demand
 End Result: Future proofed customers business needs by
increasing circuit capacity by 100% and potentially
reducing circuit monitoring costs by 50%

U-Shaped female busbars
• Creates a maintenancefree joint
• No bolted joints in
system
• No specialist team
required to install the
system
Housing couplers are used for
mechanical strength and to
carry the ground through the
aluminum housing

Power monitoring
Power monitoring with Starline
 Individual circuit and row power monitoring insures no
overloads
 The DCM can store historical data to prove customer
overloads and defend SLA claims
 Monitoring alarms in place for throw-over scenario's
preventing overloads during redundant circuit failovers
(i.e. continuously sum A & B circuits)
 Wire free implementation reduces connectivity costs and
allows remote configuration for the end user i.e. own
secure portal to their data only
