Overview

All transformers also ensure that the protective measures required by relevant standards are met, for instance in the event of a shortcircuit or voltage interruption.

Magnetic transformers are a rugged, extremely affordable solution offering long service life together with excellent thermal endurance.

Tridonic’s diversified range of units for integration in luminaires and surface-mounted applications covers all relevant uses. The transformers guarantee operation of lamps in accordance with specifications, thereby enabling lamps to achieve their maximum luminous flux and service life.

Essentially, all Tridonic magnetic transformers are characterised by minimal power consumption, compact winding, optimised dimensions and highquality materials. They are continuously controllable using phase-control dimmers for inductive loads.
 

Designed for long service life

Thanks to their high-quality insulating material, coil form and the quality of the copper wire used, KTR, TMDC, TMB and TMC type transformers for integration in luminaires and TMDD and OMT types for surface-mounted applications achieve a maximum service life of approximately 100,000 hours of operation, i.e. roughly ten years of continuous operation with a winding temperature of 130 °C ( tw = 130 °C). The winding temperature is calculated from the ambient temperature and the temperature increase due to intrinsic consumption. An upward or downward change in temperature of 10 °C causes doubling or halving of the life of the unit respectively.

The transformers can be protected on the line side either by a slow fuse or by a built-in current-sensitive thermal cutout appropriate to the transformer type. Protection on the secon-dary side against overloads and short-circuits trips if the lamp is faulty.
 

Constantly high quality

The consistently high quality and reliability of the Tridonic magnetic transformers are guaranteed by the use of high-grade materials together with manufacturing processes certified to ISO 9001. Fully automatic manufacture ensures constant reproducible quality. All transformers are subjected to 100 % final testing and safety testing.
 

Standards and approval marks

Magnetic transformers from Tridonic are ENEC certified, carry the CE mark and meet the European standard EN 61558 (IEC 61558) relating to safety, operation and electromagnetic compatibility (EMC).
 

Specialist for integrated applications

KTR magnetic transformers are characterised by especially compact dimensions (28.6 x 41.5 mm) and an excellent price/performance ratio. Power ratings range from 50 to 105 VA.

Because of their dimensions (28.6 x 41.5 mm), TMDC transformers are suitable for all applications where a device with a small cross-sectional area is needed, e.g. in tubetrack systems. This model is available with power ratings from 20 to 105 VA.

TMB transformers are compactly designed units of reduced length. The device has a cross-sectional area of 65 x 47 mm. Thanks to its high efficiency, the TMB model, which is available in versions from 20 to 300 VA, is also suitable for use at relatively high ambient temperatures.

TMC (OGT) transformers reveal their full potential in situations where several lamps are connected. Power ratings range from 250 to 500 VA versions.
 

Designed for surface-mounted applications

TMDD magnetic transformers are available as a Lovotec version and as a TMD enclosed version which are also suitable for integration or surfacemounting on furniture having unknown flammability characteristics. Thanks to their small cross-sectional area, these units are especially suitable for use in suspended ceilings.

OMT transformers are used when several lamps are connected, e.g. in the case of cord suspension or track systems. Power ratings range from 150 to 300 VA.
