Industrial AC UPS 20kVA- 160kVA

The MASTER MPS range has been enhanced with the HP series available from 100kVA to 600kVA.MASTER HP Series provides maximum protection and power quality for data centres and industrial loads. The UPS has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true On-line, double conversion power protection, (VFI SS 11 – Voltage and Frequency Independent in accordance with IEC EN 62040-3).The HP series provides exceptional operating efficiency (over more conventional thyristor rectifier-based systems), a compact footprint and easy maintenance access – all ideal for today’s critical operating environments.

ZERO IMPACT SOURCE

As an evolution of the MASTER series, the HP features the added advantages offered by an IGBT-based rectifier assembly. This further reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size.

The MASTER HP is classed as a ‘Zero Impact Source’ and provides:
• Low input current distortion – less than 2.5%
• High input power factor 0.99
• Power walk-in function that ensures progressive rectifier start up
• Delayed start up phased with the return of mains power supply, when several UPS are connected in the system.

MASTER HP also performs the role of a high performance filter, protecting its upstream power supply sources from any harmonics and reactive power generated by the loads powered.

BATTERY CARE SYSTEM: MAXIMUM BATTERY CARE

MASTER HP uses the Battery Care System, also available on the MASTER MPS models, which optimises battery performance in order to extend the battery life for as long as possible.

FLEXIBILITY

The configuration with the output transformer, a feature of both the MASTER HP and conventional series, is characterized by the galvanic isolation of the load and the battery for greater versatility in system configurations.
As a matter of fact it allows for two network inputs (main and emergency) separate, and coming from two different power sources; this is particularly suited to parallel systems in order to ensure the selectivity between the two sources, thus improving the reliability of the entire installation.

Main features
• High output power
• Compact size: only 0.85 m2 a for 250kVA UPS
• Reduced weight
• Double load protection, both electronic and galvanic, for the battery.

The MASTER HP range is suitable for use in the widest selection of application. Thanks to the flexible configurations, accessories and options available, it is suitable for powering capacitive loads, such as blade servers.
Reliability and availability of the power supply for critical applications is guaranteed by the distributed or centralized parallel of up to 8 units for (N+1) backup or power parallel, and by all the various configurations available in the MASTER MPS range.
