STATYS
REDUNDANT DESIGN FOR POWER AVAILABILITY AND SITE MAINTAINABILITY – FROM 32 TO 1800 A
Standard features
– A smart and flexible transfer system that can be configured according to the type of load.
– Synchronised and non-synchronised sources compatibility (configurable synchronisation tolerance and switching management).
– Fuse-free or fuse-protected design.
– Output fault current sensing.
– Internal CAN Bus.
– Double maintenance bypass.
– Neutral oversizing for non-linear loads compatibility.
– Embedded Inputs, output and maintenance bypass switches (cabinet version).
Inputs
Supplied by two independent alternate sources, STATYS increases the overall electrical infrastructure availability during abnormal events and programmed maintenance.
– Provides redundant power supply to mission critical loads to increase global uptime of the supplied system.
– Increases the power supply availability by choosing the best power supply quality.
– Provides plant segmentation and prevents fault propagation.
– Allows easy extension and easy infrastructure design, ensuring high availability of the power supply to critical applications.
– Facilitates and secures the maintenance or the modifications of the overall electrical installation (source, distribution, switchboard) while the load is kept supplied.
Flexibility
STATYS is available in:
– 2 wires and 2 poles switching, to be connected between phase/neutral or phase/phase.
– 3 wires arrangement without neutral for reduced cable costs and for local zoning of the applications by using insulating transformers.
– 4 wires three-phase arrangement with neutral, with or without neutral pole switching.
STATYS offers:
– Flexible digital control capacity that can adapt to any operational or electrical environment conditions.
– Capability to manage synchronised and non-synchronised sources according to load specificity.
ATSM function
Advanced Transformer Switching Management (ATSM). If the upstream network has no distributed neutral cable, two upstream transformers or one downstream transformer can be added to create a neutral reference point at the output. For the downstream solution, STATYS, thanks to ATSM, correctly manages the switching to limit inrush current and avoid the risk of spurious breakers.
Protection
STATYS also provides protection against:
– Main power source outage.
– Failures in the upstream power distribution system.
– Failures caused by faulty equipment supplied by the same source.
– Operator errors.
Applications
Data Centres – Power availability for servers
