High quality power supply

• Permanent operation in VFI mode (online double conversion).
• Output voltage precision under all load conditions.
• High overload capability to withstand abnormal load conditions.
• A very high short-circuit current capacity which facilitates the selection of protective devices for selectivity in the downstream distribution.
• An isolation transformer installed on the inverter output to ensure complete galvanic isolation between DC circuit and load output. This insulation also provides a separation between the two inputs when they are supplied by different sources.

• Sinusoidal ThdU output voltage < 2 % with linear loads and < 4 % with non-linear loads.

High availability

• Field-proven technology.
• Fault-tolerant architecture with redundancy of basic functions, such as the ventilation system.
• Easy maintainability reduces MTTR thanks to pull-out sub-assemblies and front access all components.
• Accurate diagnostics guarantee power supply to the load.
• Cascade failure prevention for parallel systems.
• Mechanical & electrical robustness for industrial environments.
• Soft start capability (ramp up) of the IGBT inverter allows a good operation even with a genset.
• Specifically designed to be adapted to different industrial environment: high IP protection options, high peak current capability, long back up time.

Parallel systems

• Distributed or centralized bypassfor parallel architecture up to 6 units.
• Redundant systems (“1+1” and “n+1”).
• “2n” architecture with Static Transfer Systems.

Standard electrical features

• Slots for 3 communication cards.
• Backfeed protection: detection circuit.
• Standard interface:

– 3 inputs (emergency stop, generating set,battery protection),

– 4 outputs (general alarm, back-up, bypass,preventative maintenance needs).
