These TRK Cofi Ignition Transformers are produced with the electronic technology of high-frequency oscillation applied to a vacuum impregnated step-up coil. The features of this transformer make it suitable for gas and oil burners where continuous power and size and weight that is less than conventional inductive transformers are required.
Medium-size conventional transformer, suitable for all kinds of gas and oil burners, where continuous or intermittent power and achievement of higher voltages and currents are required. This range is available in a great number of variations.
This TRE820PISO isolated 230V 50HZ C.440 SP transformer is the smallest in the range. It achieves the same ignition features of some medium-size transformers at a remarkably lower price. This result is due to in-depth research on materials that enabled reduction of size and smaller content of raw materials.
