CBM Transformer type T8 CM150 (replaces 15000001)

IGNITION DESCRIPTION The ignition transformers type T8… - T16/D - T18… - T20 TRANSFORMERS have the same overall dimensions, but different electric features and fixing systems. TYPES T8.. T16/D T18.. T20.. These transformers are used in different applications depending on their electric features, i.e.: − The T8/… transformers are suitable for high thermal power burners or pressurised burners for light or heavy oil. − The T16/D transformers are suitable for fluid or gaseous fuel burners. − The T18/... transformers, which are designed for permanent operation, are suitable for the application on industrial machines (e.g. water cleaners). − The T20/... transformers are suitable to equip light or heavy oil burners designed for frequent and repeated starts (e.g. burners for steam boilers, cooking furnaces, and so on). FEATURES Followings are the main features of this series: - various connection and fixing systems; - high discharge power; - high efficiency and ignition powe r.

CONSTRUCTION This series consists of column -type transformers, i.e. ignition transformers fitted with 2 primary windings and 2 secondary windings, except for type T16/D which is a shell -type transformer. All types are isolated by a special high isolation separator. High voltage isolation is achieved by means of a special kind of vacuum cast polyester resin. The housing is made of stove enamelled pressed metal. Each transformer is specified by the letter T (transformer), by one or more figures indicating the model and sometimes by some letters referring to the parti cular fixing system, i.e.: 3965_r00 1/2  TXX/X    → fixing system → model If the fixing system used is standard, the corresponding reference letter is not inserted in the part reference. For instance, the part reference T8 refers to a transformer with standard fixing system, whereas the part reference T8/B corresponds to a T8 transformer with different fixing system (see Fig.1, type B). The transformers of this series can have the same electric Fig.2 features but different fixing system s, or vice versa.
