Serial transformers KR6XX

Certificate basis

• FAAAC 150/5345-47A, ICAO Aerodrome Design Manual Part 5 Electrical Systems, IEC 61823

Description/properties

• due their low leakage inductance are suitable for use for individual lamp control and monitoring systems
• transformers are completely waterproof
• the encapsulation of the transformer is made of TPE (thermoplastic elastomer), with excellent electrical and mechanical resistance to the chemicals typical used at airfield
• thermal resistance up to 135 °C
• the transformers are available alternatively with or without earthing, the earthing connector is connected to the secondary winding
• the tranformers have two copper windings, one primary and one secondary, wound separately on a toroidal magnetic core circuit and insulated completely from each other

Primary leads

• the transformers have two primary leads, standard length 0,6 m, cross section min. 6 mm²
• one lead with FAA L-823, Style 2 plug
• one lead with FAA L-823, Style 9 receptacle

Secondary leads

• the transformers have one secondary lead of 1,2 m in length with cross-section min. 2,5 mm², min. 0,6 kV and FAA L-823 Style 8 connector
• on request, the transformers can be equipped with other cable sizes and lengths or with FAA L-823 Style 7 connector

Voltage transformers KRV/KRVS

Certificate basis

• FAAAC 150/5345-47A, ICAO Aerodrome Design Manual Part 5 Electrical Systems, IEC 61823

Description/properties

• transformers are completely waterproof
• the encapsulation of the transformer is made of TPE (thermoplastic elastomer), with excellent electrical and mechanical resistance to oil, kerosene, other aircraft, fuel, soil acids and alkalis and other chemicals typically present on the airfield.
• the plug and receptacle insulation as well as cable insulation is of the same material - thermoplastic elastomer - fully

Type KRV
