component compared with 7 years for a
typical battery.

LOW MAINTENANCE COSTS
Easy to install and maintain.

Master VDC is a scaleable system comprised
of one or more UPS units and VDC-XE
flywheels. Master VDC is ideal for modern
ECO targeted data centres looking to achieve
the lowest possible PUE ratios and highest
levels of reliability.
Master VDC UPS provide a number of
advantages over more traditional batteryequipped systems including: up to 99%
efficiency, a compact footprint (up to 50%
reduction), lower Total Cost of Ownership (TCO)
and almost instantaneous recharge times.
A single flywheel module provides sufficient
runtime for the start-up of a local standby
generator to power the UPS, which then
provides a continuous quality power supply.
The entire system can be scaled for reliable
power (N+x) and increased runtime via the
parallel operation of several UPS and/or
flywheel modules (and a small battery pack
if required, for additional reliability).
In a standard configuration (1 x UPS and 1 x
flywheel), the runtime available is more than

sufficient to allow the UPS to ride through
short breaks in mains power.

Flywheel VDC-XE
Thanks to their extremely high levels of
reliability, the VDC series of flywheel energy
storage systems provide UPS with a secure
and reliable source of power that forms the
first line of defence against interruptions
to the mains power supply; a fundamental
defence for all mission critical applications.
The VDC flywheel systems are fully
independent standalone devices. They
are designed for applications such as data
centres, hospitals and industrial installations.
They provide a clean source of back up power
by converting the kinetic energy stored
within a rotating mass into electrical power
using a built-in IGBT-based converter.
VDC series flywheels store kinetic energy
in the form of a rotating mass (spinning
at 36,000 RPM) within a vacuum-sealed
container. The VDC build technology includes
