Description
The manufacturer produces generators from 10 to 35 000 kVA and has built higher-frequency machines for aviation for about 30 years. Class H insulation, power factor 0.8. Voltage dip does not exceed 10 % at a 50 % load change, recovery time is up to 500 ms, and harmonic distortion at no load is below 3 %. The D550 regulator is compatible with all 400 Hz generators, holds voltage within ±1 % under balanced line load, protects against speed drop, has a built-in radio interference suppressor and is mounted in the terminal box. Settings are read through the EasyReg Advanced program. The D550 is also optimised for parallel operation with the grid. The frame is steel, bearing shields are steel, cast iron or aluminium, bearings are lubricated for life, and protection is IP23 with self-ventilation. Ambient temperature is −20 to +50 °C, altitude up to 1000 m, compliant with IEC 60034-1.
How to choose
Choose the generator by the required unit power and the number of bearings. Single- and two-bearing designs are available, and two-bearing machines have a standard cylindrical shaft end. If a grid operates nearby, consider parallel operation under the D550. The radio interference suppressor option is needed where radio equipment is sensitive to interference.
