Riello Master HE

Master HE

 HE - High Efficiency

Master HE series is available from 100 to 800 kVA. The UPS feature a new on-c; double-conversion technology utilising IGBT and DSP (Digital ) control to provide maximum protection, power quality and green energy for any type of application including primary datacenters, disaster recover sites, telecoms rooms, industrial processes and security applications. High efficiency stands for higher active power available if compared with legacy UPS thanks to output unitary p.f. Nominal power is granted with no downgrading independently from operating temperature.

 Characteristics

 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.

Advanced supervision Master HEP series UPS have a front panel grac 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 >

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.
