Brahma T11/M type transformer

IGNITION DESCRIPTION TRANSFORMERS Ignition transformers series T11 and T16 are suitable for fluid or gaseous fuel burners. Ignition transformers series T13 and T17, with 100% duty- cycle, are particularly suitable for the application on industrial machines (e.g. water cleaners). Type T11 and T13 FEATURES Followings are the main features of this series: - various connection and fixing systems; - high discharge power (they are particularly suitable in all those applications in which long ignition wires are required); - high efficiency and ignition power. TECHNICAL DATA - Supply voltage: 220V - 50Hz (different voltage and frequency values are available on request) - Operating temperature range: -10°C +60°C - Isolation: polyester resin - Recommended distance between Type T16 and T17 the electrodes: 3 ÷ 5 mm - Supply cable standard length: 550 mm T11/...

CONSTRUCTION The magnetic circuit across the transformer is mantle- shaped (see general features in Figure 1 and Figure 2). The secondary windings are center grounded. The transformer is provided with a radio interference suppression shield, which for its effectiveness must be connected to a good ground. Two fire painted caps cover the coils and form a whole with the magnetic circuit. Each transformer is detected by the fixed letter T (transformer), by a series of numbers that indicate the model and possibly by a letter of the alphabet which determines a particular fixing system: 29087_r00 1/3  CONNECTION T XX / X   The high voltage isolators employed in this series of  → fixing system transformers are of two different types, according as the → model connection with high voltage cables occurs by means of a screw, 4 mm diameter cylindrical terminal or of a 6.3 mm diameter cylindrical terminal. If the fixing system used is standard, the corresponding If not expressly mentioned, the connection terminal used is reference letter is not inserted in the part reference. a screw terminal. The insulators are made of PBT. For instance, the part reference T11 refers to a transformer with standard fixing system, whereas the part reference T11/B corresponds to a T11 transformer with different fixing system INSTALLATION (see table 1, type B). - Connect and disconnect the ignition transformer only after The transformers of this series can have the same electric switching off the power supply. features but different fixing systems, or vice versa. - Respect the applicable national and European standards (e.g. EN 60355-1 / EN 50165) regarding electrical safety. OVERALL DIMENSIONS - Make sure that the earth of the transformer and the earth of the electric system are well connected. Figures 1 and 2 show the main overall dimensions and Table 1 the various transformers fixing systems. - The device can be mounted in any position. - Do not put high voltage cables next to other cables. - Guarantee a protection degree suitable to the application.
