Download Factsheet 4.3MB
Power Range: 100-800kVA
HE stands for High Efficiency, so as you would expect The Riello Master HE Series has been built with efficiency in mind.The Master HE is the ideal UPS solution for primary data centres, disaster recover sites, telecoms rooms, industrial processes and security applications.
Operating at a potential 99.4% efficiency makes the Master HE comparable with all the best transformerless UPS systems available on the market today.
The Riello Master HE series is available from 100 to 800 kVA.
Zero impact source
Master HE 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
Smart Grid Ready UPS
Master HE series UPS are ‘Smart Grid Ready’ and can be used within an energy storage solution, whilst simultaneously operating at the highest levels of efficiency and automatically selecting the most efficient operating mode based on the state of the lower grid network or generator supply. The UPS are designed to electronically interface with energy management systems within an ‘intelligent’ Smart Grid application.
Master HEP series UPS have a front panel graphic display providing UPS information, measurements, status updates and alarms in different languages, with wave form displays including voltage/current and provide a kWh reading that can be used to measure IT loads and calculate a datacenter PUE (power usage effectiveness) ratio.
Battery care system
Master HE 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 two 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.
