reliability).
In

standard
configuration (1 x UPS and 1 x

more than sufficient to allow the UPS
to ride through short breaks in mains
power.
Flywheel VD C and VD C-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
