Description
Master HE
Three Phase Output AC UPS 100kVA – 800kVA
Master HE series is available from 100 to 800 kVA. The UPS feature a new on-line double-conversion technology utilising IGBT and DSP (Digital Signal Processor) 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.
Advanced supervision
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.
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.
