Case Study Waitrose
Waitrose standardises on MINIpowerPLUS for EPOS
support
Waitrose has chosen MINIpowerPLUS UPS from
Uninterruptible Power Supplies Limited to provide
flexible, easy-maintenance support for its EPOS
systems. MINIpowerPLUS is specified for all store
new-builds and refurbishments, and will gradually
replace existing UPS installations in an ongoing
swap-out programme, ultimately providing power
protection in more than 180 stores of the
Waitrose group. "When we embarked on upgrading
our EPOS systems we were unsure of the future
power requirement and a solution with flexibility
for simple expansion was essential", comments
Waitrose's Electrical Services Manager, Andy
Lowe. "In addition, MINIpowerPLUS has attractive
features for maintenance and repair which ensures
that these functions can be carried out with no
break in the power supply to the load and minimal
impact on costs. MINIpowerPLUS is a compact,
sophisticated modular UPS in which the required
output is built up using 1.25kVA boards, mounted
in rack or tower cabinets. The units specified
by Waitrose have four board slots, and are
currently populated with three boards. MINIpowerP
LUS features the unique PowerWAVE paralleling
architecture, which means that the boards can be
connected for capacity or, as at Waitrose, to
provide n1 parallel redundancy. If output needs
to be upgraded, Waitrose can expand within the
same footprint to 5kVA with redundancy, simply by
adding extra boards. Autonomy is similarly
flexible. A further innovative feature is
MINIpowerPLUS' maintenance bypass switch, which
plugs into the back of the unit and allows the
UPS to be isolated for maintenance purposes or
removed for repair, both without a break in the
supply to the load. UPS 216-01-00

"Clearly, any break in power to our EPOS systems
is unacceptable", Andy Lowe continues. "Not only
does the MINIpowerPLUS give us excellent inherent
reliability, but continues to support the load
even if one board goes down. With this facility,
we will never experience an emergency requirement
for UPS maintenance. So, in the rare event of a
UPS problem, we can call out an engineer during
normal working hours without incurring
'out-of-hours' costs, and with confidence that
there will be no interruption to our ability to
trade during maintenance operations."
MINIpowerPLUS systems are now available allowing
expansion in 1.25kVA increments up to 10kVA, and
are part of a PowerWAVE range which covers all
UPS requirements up to 3MVA. PowerWAVE
technology not only allows cost-efficient output
expansion and redundancy within a small
footprint, but also reduces running costs through
high operating efficiency and near-unity power
factor. Reading-based Uninterruptible Power
Supplies Limited is the UK's leading supplier of
power support solutions, backing its products
with comprehensive technical, installation,
commissioning and maintenance services, and with
