Master HP UPS

Master HP UPS

The Master HP range guarantees power quality and maximum resilience for applications including data centres, electro-medical devices, IT and telecommunications networks, and industrial loads. A three-phase online UPS system using advanced double conversion technology to protect against power failures and deliver a filtered, stabilised supply, it comes in 9 power ratings from 100-600 kVA. Delivers efficient performance even with partial loads. Intuitive system automatically selects the most suitable and efficient operating mode based on mains input quality.

A tower-style UPS with removable front panel for easy maintenance, the Master HP has an efficiency-boosting IGBT-based rectifier plus an output isolation transformer that guarantees enhanced load protection, provides higher immunity to any load-generated harmonics, and allows for the UPS system to be supplied from 2 independent lines. Parallel up to 8 units for increased capacity or redundancy in either a centralised or decentralised architecture. User-friendly LCD graphic display shows broad range of measurements and information, including UPS status, input and output voltage, and battery runtime.

Designed to deliver maximum power efficiently in a compact footprint, the Master HP series is a popular solution for almost any mission-critical environment.

Available in 9 power ratings from 100-600 kVA, up to 8 UPS systems can be installed in parallel to provide the necessary redundancy and capacity. Systems can be installed in centralised or decentralised architecture and in a variety of configurations, including:

  • – UPS Group Synchroniser (UGS): enables 2 or more non-parallel UPS devices to remain synchronised even during mains power failure. UGS also enables a Riello UPS to synchronise with another independent power source, even one with a different power rating.
  • – Parallel Systems Joiner (PSJ): this connects 2 groups of UPS in parallel using a power coupling switch. If one of the UPS in the group fails, it is automatically excluded and the PSJ links the remaining UPS to the other group through an external bypass.

A three-phase online UPS utilising double conversion technology, it is a proven power protection provider for data centres, electro-medical devices, IT networks, telecoms systems, and industrial machinery.

The Master HP has zero impact on connected power sources such as grid networks or generators and delivers a unity power factor. With an IGBT-based rectifier, it achieves exceptional operating efficiency compared to a more conventional thyristor-based rectifier. While its output isolation transformer means the UPS can be supplied by 2 independent lines, has a higher immunity to harmonics, and provides all-round better load protection.

Mains input quality is constantly monitored, with the system selecting the most appropriate and efficient operating mode based on any interference (Smart Active mode with up to 98.5% efficiency) or circular redundancy (Parallel Energy Saving mode).

UPS maintenance is easy thanks to a removable front panel, while high power is achieved in a compact, space saving footprint. As an example, a 250 kVA version can be installed in 0.85m2.

Users benefit from advanced monitoring and communication provided by a front panel-mounted LCD graphic display clearly showing key measurements and data, including battery levels, input and output voltage, and UPS status and alarms.

The Master HP range integrates seamlessly with PowerShield3, PowerNetGuard, and the wider range of advanced network communications software available from Riello UPS.
