AIRCRAFT MAINTENANCE MANUAL STEMME S10, VARIANT S12 3.7.2 DC GENERATION (ATA 24-30-00) 3.7.2.1 MAIN SYSTEM DC POWER GENERATION The DC power for the main system is generated by the belt-driven alternator of the engine and stored in a LiFePO4 battery.
AIRCRAFT MAINTENANCE MANUAL STEMME S10, VARIANT S12 FUNCTION When aircraft master switch is switched ON the main system master relay connects the battery to the system. From that moment on all devices supplied by main system are powered, except those with a dedicated ON/OFF switch. When the engine is running, the external alternator switch switches on the field circuit of the alternator and the alternator starts to generate voltage.
AIRCRAFT MAINTENANCE MANUAL STEMME S10, VARIANT S12 3.7.2.3 OVER VOLTAGE PROTECTION The outputs of the belt driven alternator and of the internal generator are monitored by a dedicated over-voltage device OVP. The device senses the voltage of the related system and disconnects the related alternator resp.
AIRCRAFT MAINTENANCE MANUAL STEMME S10, VARIANT S12 3.7.6 DC POWER DISTRIBUTION SYSTEM (ATA 24-60-00) The system is designed to distribute electrical energy from the source to the electrical loads. Be- cause the engine of the S12 is located in mid-fuselage, there are long distances between voltage sources and the loads.
AIRCRAFT MAINTENANCE MANUAL STEMME S10, VARIANT S12 3.7.6.3 PROTECTION DEVICES Fuses and circuit breakers of different industrial standards are used to protect each electrical circuit. The protective devices are rated according to the maximum allowed electrical load of the protected wire. Protection devices are located as close as possible to the voltage source to mini- mize the length of unprotected wire.
