ELECTRONIC IGNITION DESCRIPTION TRANSFORMERS FOR NON- These ranges of electronic ignition transformers are characterized by extremely limited overall dimensions and are PERMANENT OPERATION particularly suitable to equip forced draught burners for gas and light or heavy oil, for civil and industrial applications. The working principle is based on a high frequency electronic oscillator; the voltage it generates is then increased by using a TC....A. Series transformer with ferrite nucleus, reaching in this way output voltage values up to 15 kV. All types can be supplied with filter to minimize the emission of electromagnetic interference. In this way this series of electronic transformers is in compliance with the EMC directive 2014/30/EU without the use of external filters. The transformers of this series can also be supplied for permanent operation (100% duty cycle). For further information see relevant data sheets (TC….S. and TD….S.). FEATURES Followings are the main features of these ranges of transformers: − available with inbuilt EMC filter; − limited weight and overall dimensions; − high efficiency and ignition power; − low consumption; − single-pole or double-pole high voltage output; TD....A. Series − different fixing and connecting systems; − inbuilt protection against short circuit; − in oil and gas burners, the safety of ignition transformers depends on the control unit. APPROVALS − The transformers comply with the essential requirements of the "Low Voltage Directive (LVD) 2014/35/EU", as they are approved by IMQ according to the product standards EN 61558-1:2005 + A1:2009 and EN 61558-2-3:2010.

CONSTRUCTION The working principle based on the use of a high frequency electronic oscillator has enabled to develop a device with limited dimensions and weight, but with high ignition power. The electronic circuit and the transformer with ferrite nucleus are bathed in a special kind of resin with very good thermal conductivity and a specific coefficient of expansion, which ensures high resistance to temperature variations and to the overload due to protracted working. An inbuilt varistor protects the device from possible voltage transients in the mains supply. The transformers of these series are available in different Available in double- pole versions only versions as regards the number of poles, the position of the isolators, the type of connection, the power supply connection Fig. 1 and the availability of an EMC filter; on this subject, see the following scheme: TC1S – TC2S TC/TD X X X X A X Available in double- pole versions only : without EMC filter; F: with EMC filter; A: non-permanent operation (50% duty cycle); C: supplied with cable (Fig. 1, 2, 3 and 4); P: supplied with outlet (Fig. 6 and 7); V: screw fixing system (Fig. 8); T: fixing system with terminal ∅ 4 (Fig. 8); L: lateral isolators (Fig. 1 and 3); S: bottom isolators (Fig. 2 and 4); 1: single pole; 2: double pole; For instance, the designation TC2LVPAF indicates that the Available in double- transformer belongs to the TC series, is provided with two pole versions only lateral isolators, screw fixing system, power supply with outlet, Fig. 2 EMC filter and is for non-permanent operation. 2/4 3409_r07  TD1L - TD2L TC Available in double- pole versions only Fig. 6 Available in double- TD pole versions only Fig. 3 TD1S – TD2S Available in double- pole versions only Fig. 7 The connection of high voltage cables can be of two types, according to the terminals used inside the isolators: connections can be carried out by means of a screw or a cylindrical terminal with 4 mm diameter, as shown in Fig. 8. All connectors, including the ones complete with cable, can be Available in double- supplied on request. pole versions only Fig. 4 CONNECTION These ranges of ignition transformers have been developed in order to be used with control boxes of our own production, which can be mounted on the ignition devices by means of fixing screws type M4x45, as shown in Fig. 5.
