ZY SERIES Modular UPS, 25-400 kW
Lowest total cost of ownership and maximum availability – taking
scalability, resiliency, safety and efficiency to the next level.
The most advanced UPS in its power range, the HRD ZY is ideal for
small to mid-sized data centres and other mission critical
applications where efficiency, reliability, safety and scalability
The rapid adoption of the cloud, constant evolution of IT
technologies, increased focus on environmental footprint and
sophistication of mission critical applications is demanding even
more efficient, resilient, scalable and safe power protection
The new levels of efficiency and scalability offered by the ZY
minimise Total Cost of Ownership while the safety and resiliency,
both in infrastructure and IT layers, maximise availability and
ensure business continuity.
Available in 200kW frame sizes, the modular design of the ZY
enables it to suit a wide range of requirements. And, whichever one
you choose, you can be sure it will provide the lowest Total Cost
of Ownership combined with maximum availability, for cost-efficient
Ensuring that you can always access the power your mission critical
application requires – under all circumstances – without
compromising business performance or safety, the ZY is the most
efficient, scalable, Cloud-ready and safe UPS you can choose.
With high efficiency being translated into reduced electrical and
cooling losses, it helps to minimise operational expenditure costs,
in addition to addressing the cost pressures esulting from
commoditisation of IT services. Increased efficiency also leads to
higher sustainability, through reduced carbon emissions.
Scalability helps to optimise capital expenditure by only deploying
additional equipment when necessay and providing additional
flexibility to respond to your changing needs. The scalability of
the ZY also
provides increased flexibility to accommodate the changing
requirements of rapidly evolving technologies.
Resiliency, virtualisation & cloud-readiness
The ability of a system to absorb faults and still remain in its
desired operational state is paramount to minimising costly
downtime. The ZY takes resiliency to the next level by bridging
electrical and IT infrastructures.
Ensuring safety in any electrical installation is a must. Safe
hot-swappable design and in- built back-feed protection ensures
safety and compliance with regulations.
Maximum Energy Efficiency Lowest TCO
the ZY series is simply the most efficient UPS in its class,
offering the lowest total Cost of ownership. thanks to the advanced
algorithms and energy- saving features, the ZY achieves up to 99%
efficiency. this efficiency is well proven with installations in
major datacentre hubs in the Asia Pacific region and around the
99% efficiency - Energy Saver System (ESS)
The ESS enables the ZY efficiency to reach an impressive level of
99% by suspending the power modules when power conditioning is not
The power is fed through the static bypass switch, and in the event
of exceeding pre-set input limits, the UPS is ready to switch to
double-conversion mode in under two milliseconds. In addition to
extremely low losses, the ESS mode provides filtering against fast
low-energy transients. It is simply the most advanced, most
reliable, fastest-reacting energy-saver architecture available.
In addition to saving energy, this technology enhances the
reliability of the system by reducing electrical stress in the
power electronic components, extending the UPS life time and thus
reducing total cost of ownership.
Efficiency in all modes
Load (% of nominal)
optimised double conversion efficiency - Variable Module Management
For applications where ESS may not be optimal, for example with
very low quality mains, VMMS technology includes automatic variable
power module management. The system automatically suspends and
engages modules as appropriate, to optimise efficiency both at UPS
and system level.
VMMS helps you achieve high efficiency even when UPS load levels
are low – typical for redundant UPS systems. VMMS can optimise the
load levels of power modules in a single ZY UPS or in parallel
systems, by suspending extra UPS capacity. This means not only
greater efficiency at lower load levels, but optimum efficiency at
all load levels.
The ZY UPS 25kW UPM (Uninterruptible Power Module)
Maximum double conversion efficiency
The ZY UPS still offers the highest double conversion efficiency in
the market, reaching
Highest power density
The unity power factor maximises the true available power of the ZY
UPS. This means it can deliver up to 20% more real power than other
in it's class.
The highly scalable nature of the ZY UPS means that scaling up in
response to increased demand takes minutes rather than hours.
Scaling up can also be achieved without increasing the footprint –
saving valuable floor space. The modular design allows for internal
redundancy, which eliminates.
The scalability can be reached by paralleling up to 4 frames for a
total system size of up to 800 kW.
Maximum availability is integral to business continuity, and
integral to the design of the HRD ZY UPS. It ensures you can always
access the power your mission- critical application requires.
Hot swappable and hot scalable
Due its modular design, a ZY power module can be replaced or added
while another module continues protecting the load. This eliminates
the need to go to bypass for module replacement or upgrading (MTTR:
0 minutes). Replacement and upgrade (N+1) operations typically take
less than 10 minutes.
The centralised topology of the ZY is ideal for scalable systems,
as it provides full bypass capacity from day one, whereas modular
designs with static switches in every power module can have a
negatIve impact on the selectivity of the system due to undersized
static bypass. This can compromise the availability of the overall

The HRD ZY UPS is designed for the most advanced IT environments,
and it comes with interfaces for Web and SNMP as standard.
In the event of an alert, the UPS system notifies users and
administrators by email. If there’s a prolonged power failure, the
protected computer systems can be shut down smoothly using the
Intelligent Power® Protector software also incorporated with the
Your ZY can be connected directly to your corporate network and the
internet. This means you can monitor and manage your UPS through a
standard web browser.

Intelligent Power Manager® (IPM) can be used to monitor and manage
all Intelligent Power Protectors running in the network. This
dramatically reduces the administrator’s workload, and minimises
the possibility of error.
