Description

Riello Master HE Zero impact source

Riello 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

Riello 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.

Advanced supervision

Riello 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

Riello 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.
