Transformerless Power Equals Efficiency
HM Cragg Helps Reduce TCO & Capital Expenditures With 400V UPS Solutions
Maximizing your energy
output and increasing overall
availability within the data center is simpler than you might
assume, thanks to the very distinct advantages of a transformerless power chain design.
Practically speaking, though,
how does a data center “go
transformerless”? It’s all about
the type of UPS you implement, according to Matt Burkle,
national channel manager at
HM Cragg.
“The UPS should be chosen
based on the current IT load
while considering future growth
and runtime needs,” Burkle
says. “From there we design
the power distribution concept
to feed each rackmount ePDU
with 230 volts while ensuring
the ePDU is able to take this
higher voltage.”
Opting to run transformerless power takes out a potential
point of failure and removes heat
normally generated by the transformer. What truly sets transformerless power apart from standard power distribution, is that
it lets you to feed a data center
UPS with 400 volts, Burkle says.
“You can derive 230 volts
off of the UPS without a transformer and feed it directly to the
IT load, which can usually take
between 100 and 250 volts,” he
says. In fact it takes less conductor material to run a higher
voltage—plus the system runs
more efficiently than standard
120/208 three phase.
By omitting multiple isolation transformers required in the
480V and 600V systems, you
can effectively lower capital
expenditures and enable your
system to perform more reliably. So in the simplest terms,
transformerless power lets you
operate a 400V data center.
Bearing this in mind, enterprises seeking to improve their
power efficiency by implementing this design can look
to HM Cragg, a distributor that
embraces the latest developments in UPS technology. P
