DELPHYS MX Elite 250-300-400-500-600-800-900 kVA

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

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

High efficiency in VFI mode, including the transformer
High power density: its small footprint saves space on your premises
The high and constant input power factor helps limit the dimensions of your upstream network infrastructure
Mains connection of the rectifier requires only 3 cables (no neutral)
High short-circuit capacity simplifies downstream protective devices

Backfeed protection: detection circuit
Standard interface:
- 3 inputs (emergency stop, generating set, battery protection),
- 4 outputs (general alarm, back-up, bypass, preventative maintenance needs)
EBS (Expert Battery System)

GTS (Graphic Touch Screen)
ADC interface (configurable voltage-free contacts)
