BRAHMA TC1LTCAF 15910403 transformers are characterized by extremely compact overall dimensions.

All types of BRAHMA TC1LTCAF 15910403 ignition transformers can be supplied with a filter to reduce electromagnetic interference. In this case, the electronic transformers comply with the requirements of Directive 2004/108/EC without the use of additional external filters.

The BRAHMA TC1LTCAF 15910403 ignition transformers also have versions for continuous operation (100% duty cycle).

The device

They are used in gas burners, burners for light and heavy types of liquid fuels in both domestic and commercial as well as industrial installations.

The principle of operation

The principle of operation is based on a high-frequency electronic generator; the voltage produced by it increases due to the use of a transformer with a ferritic core, reaching output values up to 15 kV.


  • The main characteristics of this series of transformers:
  • Possibility of delivery with built-in EMC filter;
  • Light weight and compact size;
  • High efficiency and ignition power;
  • Low power consumption;
  • Single or double-pin high voltage output;
  • Various mounting and connecting systems;
  • Built-in short circuit protection;
  • In gas and liquid fuel burners, the safety of ignition transformers depends on the controller.


The BRAHMA TC1LTCAF 15910403 ignition units meet the requirements of the Low Voltage Directive (LVD) 73/23/EEC, as they have an IMQ resolution in accordance with the standards EN 61558-1:1997 + A1:1998 +A11:2003 and EN 61558-2- 3:2000.

The principle of operation, based on the use of a high-frequency electronic generator, made it possible to create a device of compact dimensions and low weight, but with high ignition power. The electronic circuit and the transformer with a ferritic core are treated with a special compound with high thermal conductivity and a special expansion coefficient, which provides protection against temperature fluctuations and overloads caused by prolonged operation. The built-in varistor protects the device from possible power surges in the power supply network. BRAHMA TC1LTCAF 15910403 high voltage transformers are available in different versions: with different number and position of contacts, types of high voltage connections and power cable, with/without EMC (electromagnetic) filter.


BRAHMA TC1LTCAF 15910403 high-voltage transformers can be used with Brahma controllers, which can be installed directly on the transformer using M4x45 screws. All BRAHMA TC1LTCAF 15910403 ignition transformers can be supplied with either a built-in power cable or a connector for it.

The connection of the high-voltage cable is carried out inside the insulator and is available in 2 versions: threaded connection, or connection with a connector ø4 mm. All connectors, including connectors with cable, are available on request.
