Short Description

Rotary frequency converter 50/60Hz - 400Hz, also known as a motor-generator system for 400Hz output frequency. Motor-generator product line DBF400T4 Includes a 4-pole synchronous motor and a 32-pole synchronous generator, coaxially mounted and compactly housed within the frame. The motor and generator rotate together at 1500 or 1800 rpm, producing a precise 400Hz output frequency across the entire load range from 0% to 100%.
 
These products are all designed for continuous operation; the generator delivers a clean 400Hz power source isolated from switching fluctuations, voltage fluctuations, and grid noise. DBF400T4 is equipped with outstanding technology featuring a reliable excitation system, a precise voltage stabilizer, no electromagnetic wave interference, and standard sine-wave voltage. In particular, it has a compact integrated structure, is easy to operate, and has a long service life. DBF400T4 is mainly used for the navy and air force, missile systems and ground support systems, radar and transmission test systems, aviation, and laboratories. These products are able to withstand high overload, offer high mobility, and withstand harsh environments. This is why these products are suitable for military applications.
 
One option for this generator engine system is that it can be mounted on weather-protection enclosures, containers, etc.

      Power supply for aircraft

      Aircraft power is 400Hz power; while the aircraft is operating, power is generated by the generator on the aircraft. However, once it lands, the aircraft cannot keep its engine running to supply power to itself while on the ground. The frequency converter supplies power to the aircraft throughout the time it is parked at the airport. The main fields using this are the Navy, the Air Force, and civil aviation

      Power supply for Radar (Testing and Operating)

      Radar and ground transmission systems both use a 400Hz power source. The main fields using radar are military and telecommunications.
