Main features:

Maximised cost savings

The Master HP has the ability to monitor the mains input quality and to select the best operating mode based on the interference present (Smart Active mode) or circular redundancy (Parallel Energy Saving mode, which allows the UPS to regulate available capacity based on the immediate demands of the load, automatically switching to standby in the event of excess capacity), the Master HP also offers high levels of efficiency for partial loads, resulting in reduced operating costs.

Features

• High efficiency (up to 98,5%)
• Compact size: e.g.: only 0,85 m2 for the Master HP 250 KVA
• Reduced weight
• Double load protection, both electronic and galvanic, towards the battery.

The entire Master HP range is suitable for use in a wide range of applications. Thanks to the flexibility of configuration, available options and accessories, it is suitable for supplying any type of load, e.g. capacitive loads such as blade servers etc.

Power supply reliability and availability are ensured for critical applications by distributed or centralised parallel configurations of up to 8 units, for redundant (N+1) or power parallel configurations and all the different configurations offered by the Master MPS range.

Zero impact source

Master HP has a zero impact on connected power sources – grid networks or generators:

• < 3% input current distortion
• Input power factor 0,99
• power walk-in function – to ensure a progressive rectifier start-up
• start-up delay function – to restart the rectifier when the mains power supply is restored.

Battery care system

Master HP series UPS include a range of features designed to prolong battery life and reduce their usage.

Output isolation transformer

• Better load protection from DC/Battery problems
• The UPS can be supplied from 2 independent lines
• Fault on DC bus will not affect the by-pass availability
• High Short circuit current
• Higher immunity to harmonics or energy backfeed generated by the load.

Advanced supervision

Master HP series UPS have a front panel mounted graphic display providing UPS information, measurements, status updates and alarms in different languages, with wave form displays including voltage/current and providing a KWh reading that can be used to measure IT loads and calculate a datacentre PUE (power usage effectiveness) ratio.

Smart Grid Ready

Being smart grid ready, Master HP allows for the implementation of power accumulation solutions, and at the same time ensures extremely high levels of efficiency. It is also able to independently select the most efficient operating method based on the status of the grid. Master HP UPS are also able to electronically interface with the energy manager using the smart grid communication network.
