Magnetic chokes for fluorescent lamps

EC magnetic chokes for fluorescent lamps and compact fluorescent lamps and the luminaire insets for compact fluorescent lamps UEC are robust and extremely cost-effective solutions with long lives. The wide range of low-loss ballasts in energy efficiency classes B2 and B1 from Tridonic.Atco covers all the relevant applications and ensures that the lamps are operated as specified.

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 B1 version offers additional benefits thanks to its lower energy consumption and 15 K lower self-heating. What’s more, super low-loss chokes in extended lighting systems save up to 30 % energy and therefore increase their operating efficiency. 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 to low or too high the lamp electrodes will be destroyed and the life of the lamp cut short.The chokes ensures 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 TridonicAtco 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, control gear in the EC, OM and OG series from TridonicAtco 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 tempera- ture plus the increase in temperature due to the power consumption of the unit. A change in temperature of 10 °C up or down 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 ballasts are subjected to 100 % final testing and safety testing.
