Lower Total Cost of Ownership

• Minimized running costs, by:

- very high efficiency of up to 93.5% (VFI mode),

- ‘Energy saver’ automatically adapts the number of running units to the real load,

free-cooling compatible.

• Reduced footprint.

• Exceptional high power density (the most compact unit of its class): 900 kVA in less than 3.2 meters (width) per unit including the bypass.

• PFC “clean input” rectifier (without filters) with a lasting high input power factor whatever the operating conditions.

• Intelligent built-in battery monitoring system interacts with “charging mode” to prolong battery lifetime.

• Leading power factor load compatible without derating.

High reliability and availability

• Internal fault-tolerant architecture with internal redundancies and fan failure localisation.

• Intelligent embedded battery monitoring with failed block localisation and preventative remote alarm.

• Able to withstand an output short-circuit and overload.

• Reliable and robust paralleling mode.

• Multisystem automatic cross synchronisation (ACS) for an optimized use with STS.

• Output isolation transformer to reduce the influence of N-GND (Neutral Line-to-Ground) voltage and load harmonic current on UPS inverter.

Flexible architecture

• Parallel system with modular units.

• Powerful central bypass for power extension or redundancy.

• Tier 3 and Tier 4 compatible.

• Designed for optimal use with STS in downstream network.

User-friendly operation

• A control panel with graphic display for more ergonomic operation.

• An array of “com-slot” plug-in communication interfaces, for upgrading your operating requirements.

• Reduced MTTR thanks to extractible power bridges or fans on “cassette”.

• Front accessibility for all components.

User-friendly operation

• A control panel with graphic display for more ergonomic operation.

• An array of “com-slot” plug-in communication interfaces, for upgrading your operating requirements evolution.

Simplified maintenance

• Easy remote monitoring via web browser or via customer’s supervision systems (web, intranet, extranet…).

• Very open connectivity (Modbus/Jbus, Jbus tunnelling, LAN).

Simplified maintenance

• To fulfil the most demanding needs for power supply availability, flexibility and the installation to be upgraded.

• Modular parallel up to 6 units, development without constraint.

• Double bypass, for easier operation.

• Twin channel architecture with Static Transfer Systems.
