Power conversion products

Aircraft Ground Service Supplies (AGSS)

The AGSS provide onboard electrical power for the servicing and maintenance of embarked aircraft. EMS offers AGSS power converters for both 400Hz, 3-phase AC supply, MIL-STD 704 and for 270V DC supply. These converters are to be installed on the UK's Queen Elizabeth II class aircraft carriers.

270V DC

The 270V DC converters generate a highly accurate, low ripple 270V DC supply from the ship's AC power supply.

Features:

  • High bandwidth control / regulation
  • Low input power distortion
  • Transformer isolation
  • High-performance 28V DC ancillary supply to the aircraft
  • Forced-air cooling
  • Cubicle configurations for normal power, high power and dual outputs



400Hz

The 400Hz static frequency converters generate a high quality, 3-phase, 4-wire, 400Hz AC supply from the ship’s
3-phase, 60Hz power supply.

Features:

  • High bandwidth control / regulation
  • Very low distortion of input supply
  • Transformer isolation
  • 28V DC auxiliary supply
  • Forced-air cooling
