Today electrical system equipment are designed as “add-on” philosophy, they can draw electrical power from generators up to over load without any control of this request. Distribution system is transparent to this behaviour and it’s made by hardware devices providing wiring fault only in order to avoid a wiring escalation in case of wire fault.Generators are capable of 150% and 200% of nominal power for 5 minutes and 5 sec respectively. To meet these requirements generator are over-sized, anyway a long lasting overload request will be faced by shedding not flight safe essential landing load. This policy is called load managmentThe trend of “all-electrical” aircraft and green constraints calls for deep change in load management philosophy, the equipment will be useful during flight testing of EPC and flight demo.The current proposal is aligned to the new calls for greening and fully useful to develop a new generation Electrical power centre able to manage power and loads efficiently.Dana srl is proposing to develop a new Programmable Resistive Electrical Load with an Advanced Power Supply Module, having a 20 years experience on electrical load manufacturing, ensuring excellent reliability and easy to use GUI.This equipment will be named “DSOT300-125S” and will ensure fast response to input voltage transient ensuring optimum performances even testing an EPC in voltage chopping mode.Special request of qualification test will be fully satisfied, and the need for speed of loading the EPC will be ensured by a new analogue and digital redesign using solid state resistors specifically designed for this proposal.The equipment will be low temperature drift less than 0.1%.This equipment will be named “DSOT300-125S” and will ensure fast response to input voltage transient ensuring optimum performances even testing an EPC in voltage chopping mode.
