From the electrical system architecture down to the detailed definition of the ice protection controller, our electrical experts are here to help you.
The ice protection heater power supply can be AC three-phased (115/200V), HVAC three-phased (230/400V), HVDC two wires (270Vdc) or HVDC three-wires (+/-270Vdc).
We can include electrical power converters modules (AC or HVAC to HVDC TRUs). The controller logic core can be a simple control/monitoring or have greater complexities (e.g. built-in test for precise failure localisation, failure code recording and transmission etc). Electrical power values start from hundreds of Watts up to tens of kWatts.
For Controller cooling, if the aircraft blown air is not available, the controller can be autonomous by having its own blown air system (electrical fans).
Power management redundant architectures and independent control/monitoring, can be provided, for complying with critical safety requirements.
