Brahma 15910670 TD2LTCSF ignition transformer

The BRAHMA TD2LTСSF 15910670 ignition transformers are characterized by extremely compact overall dimensions.

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 is based on a high-frequency electronic generator; the voltage produced by it increases due to the use of a ignition unit BRAHMA TD2LTСSF 15910670 with a ferritic core, reaching output values up to 15 kV.

All types of BRAHMA TD2LTСSF 15910670 transformers with ignition cable 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. BRAHMA TD2LTСSF 15910670 transformers also have versions for non-permanent operation (50% duty cycle in 2 minutes).

Specifications

• The possibility of delivery with an integrated EMC filter;
• 100% duty cycle;
• 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.

Permissions

BRAHMA TD2LTСSF 15910670 transformers meet the requirements of the Low Voltage Directive (LVD) 73/23/EEC, because they have an IMQ resolution in accordance with the standards EN 61558-1:1997 + A1:1998 +A11:2003 and EN 61558-2- 3:2000.

Construction

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. These transformers are supplied in different versions: with different number and position of contacts, types of high voltage connections and power cable, with/without an EMC (electromagnetic) filter.

Connections

BRAHMA TD2LTСSF 15910670 ignition transformers can be used with Brahma controllers, which can be installed directly on the transformer using M4x45 screws. All 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.

Installation

• ATTENTION! HIGH VOLTAGE.
• Connect and disconnect the BRAHMA TD2LTСSF 15910670 transformer only after the power is turned off.
• The installation is carried out in accordance with national and European standards (e.g. EN60355-1 / EN50165) for electrical safety.
• The installation must ensure that the valve body is connected to the ground to provide protection against electric shock (EN60335-1).
• The transformer is installed in any position.
• Do not place high-voltage cables next to other cables.
• Ensure the appropriate level of protection for this installation.
