NextEnergy is the latest
UPS series designed for mission critical applications. The three-phase UPS offers
transformer-free double conversion technology VFI SS 111, with
integrated the latest IGBT three-level design.
NextEnergy is designed to meet the power requirements of
tomorrow, offering the highest efficiency in the market and low running
cost. Thanks to the Efficiency Control System (ECS)
NextEnergy also guarantees the highest levels of efficiency
even at partial loads.
Its unity power factor and easy system upgrading make it the ideal solution
for the business continuity of any IT application.
Outstanding performances
- Best-in-class performance: unity power factor (kW = kVA) and capability to supply capacitive loads (very common in most Data Centers) without any power derating up to 40 ° C obtainable thanks to the use of state-of-the-art technology and the selection of high quality and highly reliable components.
- Outstanding system efficiency up to 97% in ON LINE double conversion mode, increasing to 98.5% in ACTIVE ECO and 99% in STANDBY Mode.
- In order to guarantee the best operating level and lifetime of the UPS, particular attention was given to the automatic control of the fan speed which constantly adjusts to the specific load level, to the fan failure alarm and to the fan redundancy.
Smart Battery Management (SBM)
The battery is one of the most important parts of the UPS that
ensures energy and therefore the correct operation in case of mains
failure. NextEnergy includes all the latest features to
extend the battery life and keep the battery working
efficiently, as well as advising users about any potential
problems.
The variety of charging methods and the smart control system allows the use
of the most common type of battery and technologies available on
the market such as VLRA, AGM, GEL, NiCd as well as lithium Ion
batteries, supercaps and flywheels.
Operation without Neutral
NextEnergy can work with or without the neutral line (N). This is an important feature to reduce the TCO related to the distribution system, when the neutral line is created by an isolation transformer close to the load: for example, in the modern Data Centre, or where the neutral is not used at all. This allows reduced cost of the distribution arrangements.
Easy installation
The small footprint of the cabinet and complete front access for all
maintenance activities, ensures maximum space for installation
and service.
NextEnergy includes top and bottom cable entry as standard,
removing the need for large and costly top entry cabinets, and
ventilation is from the front to the top so no additional rear
clearance required.
Maximum reliability and availability
NextEnergy UPS can be connected in parallel up to 8 units to
increase the capacity or add redundancy (N+1).
Considering that a typical load can vary from 20 to 80%, the
Efficiency Control System (ECS) function optimizes the operating efficiency
of the entire system according to the power absorbed by the load.
This ensures higher overall efficiency during all load conditions.
Hot System Expansion (HSE) allows the addition of further
UPS into an existing system, without the need to switch off
the operational units or transfer them to bypass mode.
This guarantees maximum load protection, even during maintenance
and system expansion.
Advanced Communication
NextEnergy is equipped with a Touch screen 7” graphic color LCD
display providing all the information on the UPS, measurements, voltage
and current waveforms, operating states and alarms in many
different languages.
The panel is used for the configuration and setting the parameters of
the UPS with 3 levels of the security password based on the
authorization level ensuring “actions based on skills/responsaility”
policy.
