Optimum load protection

• Permanent operation in VFI mode (online double conversion).
• The inverter isolation transformer provides galvanic separation both between the DC current and the load and between the two sources.
• Output voltage precision under all load conditions.
• High overload capacity to withstand abnormal load conditions.
• Easy maintainability reduces MTTR thanks to pull-out sub-assemblies and front access to all components.
• Fault-tolerant architecture with built-in redundant components.

Flexible and easily upgradable

• Robust and reliable paralleling mode.
• Distributed or centralised bypass ensures perfect compatibility with any electrical infrastructure.
• Hot-plug capability simplifies extension or redundancy while keeping high quality power.
• The transformer based topology is adapted to all kinds of electrical installations.

Standard communication features

• Dry-contact interface (configurable voltage-free contacts)
• 3 slots for communication options

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).

Parallel systems

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