Isolation Transformers

The series isolation transformer secures the power supply to airfield lighting circuits and provides electrical isolation between the primary and the secondary circuit. Ratings cover 10 to 300 W, with a power factor (PF) of 0.95 or better and a rated current of 6.6/6.6 A, and it supports accurate dimming; the circuit keeps running when a single lamp fails, and both grounded and ungrounded types are available. The product meets a number of industry standards, including ICAO, MH/T 6008, IEC 61823 and FAA AC requirements. The transformer body and the leads are all injection molded in TPE, giving strong insulation and water resistance; the body is square, conversion efficiency is high and the failure rate is low. It works from -55 °C to +65 °C and suits installation conditions such as suspension in a cable pit, the pit floor or the inside of an isolation transformer box, with 10 years of proven use in the field.
