Power supply and motor drive (PSMD) for Oven

The PSMD contains all the power generating system components to control the heaters and fans for cabin oven equipment.

It includes the following functions:

  • Compatible with wild frequency network
  • Internal fault diagnostic (BITE) – improve reliability and avoid inflight failure
  • 3 phases- 3200 Volts amps- power supply for heaters
  • 250W power supply for sensorless motor
  • Active power factor corrector rectifier- with the last norms (including harmonics), last A/C
  • Protection against over current, over voltage, under voltage and over temperature
  • CAN bus communication

Key features

  • 3 phases 115 Volts alternating current(VAC)-variable frequencypower input
  • Active power factor corrector
  • Sensorless motor drive

Applications

  • Airbus civil aircraft
  • Boeing civil aircraft
