S POWER Cable Coil

The 400Hz Cable coil is a bridge mounted cable distribution system and specifically designed to accompany the Hitzinger S-Power bridge mounted converter. As an alternative to traditional cable crocodiles, this bridge mounted system has a motorised coil that allows for easy operation for the operator and designed to protect the 400Hz cable when not in use. Bridge mounted units are designed to under hang from any air bridge system with specifically designed mounting plates.

Technical highlights

From installation and commissioning to continuous use, the
S POWER is characterised by its reliability and ease of operation.

Highest efficiency
Thanks to the intelligent partitioning of the individual stacks and the way in which they are combined, the S POWER guarantees extremely high efficiency under partial and full load.

Optimised voltage quality
For optimum compensation of the voltage drop even under asymmetrical loading, the S POWER is equipped with line drop compensation (LDC) for each individual phase.

Maximum security of supply
The plug&play system of the stack technology enables simplified servicing of the individual stacks. Redundant operation is possible even if one of the stacks fails.

Optimum serviceability
With remote maintenance, all important operating states can be displayed and parameterised, and fans are regulated by temperature monitoring. Exact fault notifications help to reduce maintenance times and servicing effort.

Simplified user operation
The touchpanel of the control station offers intuitive user navigation. Easy to read even in strong sunlight, it is also dust- and water-tight and suitable for use in the most adverse airfield conditions. The resistive touchscreen is straightforward to use even when gloves are worn.
