Frequently Asked Questions

What is the COFI TRK2-35 ignition transformer used for?

The COFI TRK2-35 is an oil-filled ignition transformer designed for industrial burner and combustion systems. It provides a 12000 V secondary output to reliably ignite gas or gas-oil burners in boilers, furnaces, and process heaters. The transformer must be used with a control unit and the electrode gap should be set between 2.5 and 5 mm.

What are the specifications of the COFI TRK2-35 transformer?

The COFI TRK2-35 operates on 220-240 V primary at 50/60 Hz, delivering 2x10 kV RMS secondary voltage (12000 V peak). It draws 0.275 A primary current with 63 VA apparent power. The unit has a PBT enclosure with epoxy thermosetting resin inside, a 3x0.50 mm PVC cable 380 mm long, and weighs 0.32 kg.
