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 world.

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 required.

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.

optimised double conversion efficiency - Variable Module Management System (VMMS)

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.

Maximum double conversion efficiency

The ZY UPS still offers the highest double conversion efficiency in the market, reaching

above 96%.

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

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.

Centralised topology

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 severe

negatIve impact on the selectivity of the system due to undersized static bypass. This can compromise the availability of the overall system.

Take complete control

Managing and controlling your ZY UPS is easy. Designed for the most advanced It environments, the ZY comes equipped with intuitive user interfaces, a large touchscreen LCD providing useful status information and back logs, and a full suite of power management and connectivity options.

the complete solution

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 ZY.

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.

Information, access, ease of use

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.

The web-based interfaces of the Intelligent Power software simplify usage, by allowing access from any computer in the LAN, as well as remotely via the internet. Power information is consolidated in the same tool used to monitor and manage physical and virtual servers, storage and networks.

In the event of power failure, IPM can trigger protective actions such as live migration of virtual machines, controlled shutdown, or disaster recovery.

Intelligent, intuitive, integral

The world-class Intelligent Power Manager intelligent software solution of your ZY UPS plugs into leading virtualisation management systems, including VMware vCenter, Microsoft SCVMM and Citrix XenCenter.

This user-friendly monitoring tool enables you to monitor and manage your UPS system as an integral part of your power infrastructure. It collects data through the network, then stores it in a database for viewing and analysis.

Easy management

The ZY UPS provides easier access to detailed status information through its large, user-friendly 7” LCD touchscreen interface.

With the graphical LCD interface you can track stats on energy savings, battery time, outage tracking, load profiling and much more.

The green/yellow/red LED light-bars make system status visible from a distance in data centres.
