Frankfurt/Germany
Complete energy management and reporting for the data centre to optimize energy usage and achieve full
electricity cost transparency for the invoicing of hosting services
Johnson Electric
|
Shenzhen/China
The first step in energy management starts with the measurement, visualization and analysis of ener-
gy consumption. A wise saying which pays.
Lötschberg Base Tunnel
|
Switzerland
The third largest tunnel in the world, 34 km in length, built to cross the Swiss Alps, relies on Saia®PCD control-
lers to guarantee the correct functioning of all technical installations

Wusys wanted to manage the glo-
bal energy needs of data centres:
monitoring and optimising PUE,
managing all thermal aspects and
all primary safety elements such as
leakage detection and connection
to the fire detection equipment.
Johnson Electric, the global leader
in electric motors, equipped a first
factory with 74 Saia electricity me-
ters connected to Saia® PCD con-
trollers for data collection and com-
munication to the ERP to detail the
analysis down to the value adding
Every 333m, cross tubes connect
the main tunnels and house, in
air-conditioned technical contain-
ers, all the equipment related to
fire protection, radio networks,
lighting, CCTV and ventilation. In
total, 30000 I/O points are perma-
Wusys operates several data cen-
tres and collects data via SNMP.
Thanks to their standard commu-
nication capabilities, Saia® PCD
controllers were used to bridge the
gap between the IT world and the
HVAC/electrical world. The addi-
processes and machines. The quick
set up of the installation made it
possible to get live data in a very
short time. The immediate results
were impressive and made it possi-
ble to correct electrical installation
problems such as low cosφ. JE de-
nently controlled and monitored
by Saia® PCD controllers. The first
refurbishment of these installations
has been carried out to eliminate
obsolete material from various sup-
pliers. Thanks to our long life cycle
approach, Saia® PCDs were chosen

solution was quite natural and the

data needed to profitably operate
the data centre.
tected inefficient equipment com-
ponents and replaced oversized
pieces of equipment with ones of a
suitable size. The return on invest-
ment of this installation was less
than 3 months: enough to motivate
JE to start in other factories as well.

network to 100000 physical data
points. Proof that the slightly high-
er expenditure on quality products
pays off in the long run.
