SE 28 400-600A Converter

ELIT Srl designs and manufactures 400Hz static frequency converters since 1987. To complete the airfield range of products are available 400Hz static frequency converters, 270Vdc ground power units, constant current regulating units (CCR) for ground lighting and control systems for commercial and military airports. All the equipment is distinguished by the use of technologically advanced components, reliability, and ease of maintenance.

Description

The SE 28 600 ground power unit, equipped with a totally controlled thyristor rectifier, feeds a 28Vdc power supply by converting the mains voltage to 50 / 60Hz in a stabilized, galvanically insulated continuous voltage with voltage ripple lower than 1%. The control logic stabilizes the output voltage both statically and dynamically. Available in fixed, mobile, under bridge mounting or as an additional module to the 400Hz converter. It is a reliable solution for aircraft powering in hangars or on the airport runway outside.
