400Hz - 50Hz Systems

dubasFC

These range of frequency converters are primarily used in Defense and Avionics applications. In many of the defense and avionics premises, 400Hz supplies are available. Dubas provides custom built converters for converting these power sources to 50Hz at specified voltages to cater to specific 50Hz based loads. Dubas offers wide range of products in this product segment to meet application needs with specified input or output voltage and phases. The systems can be built to comply with specific customer requirements of dimensions, operating conditions and standards as well MIL compliances.
