Overview

All EC magnetic chokes for luminaire installation are characterised by minimal energy consumption, compact windings, optimised dimensions and high-quality materials.

In temperature-sensitive applications, the EEI = B1 version offers additional benefits thanks to its lower energy consumption and 15 K lower self-heating.
 

Optimised for specified lamp operation

EC magnetic chokes ensure that the preheating current, ignition voltage and lamp current all remain within the specified tolerances for optimum operation of fluorescent lamps.

Long lamp life can only be achieved by preheating the electrodes before the ignition voltage is applied to the lamp. The EC units heat to precisely the right temperature because if the preheat current is too low or too high the lamp electrodes will be destroyed and the life of the lamp cut short.

The chokes ensure a sufficiently high ignition voltage after the preheat phase by opening a glow starter or electronic starter. The latter automatically selects the right time to open the starter to reliably ignite the lamp at very high or very low ambient temperatures.

The EC chokes are designed to very narrow tolerances so the impedance perfectly limits the lamp current and maximum luminous flux is achieved.

The low magnetic leakage field – and therefore the very low noise emission – means that the magnetic chokes from Tridonic can be placed near electrical equipment that is sensitive to interference.
 

Design for long life

Because of their high-quality insulation material, coil core and copper wire, chokes in the EC series from Tridonic achieve a maximum life of approximately 100,000 hours of operation, in other words about ten years of constant use at a winding temperature of 130 °C (tw = 130 °C).

The winding temperature is the ambient temperature plus the increase in temperature due to the power consumption of the unit. A change in temperature of 10 °C down or up leads to a doubling or halving of the life of the unit.
 

Constant high quality

Uniform high quality standards are guaranteed by the use of high-grade materials together with manufacturing processes certified to ISO 9001. Fully automatic manufacture also ensures constant reproducible quality. All the chokes are subjected to 100 % final testing and safety testing.
 

Standards and approval marks

EC magnetic chokes from Tridonic are ENEC certified, carry the CE mark and meet all the relevant European as well as international standards relating to safety, operation and electromagnetic compatibility (EMC).
