Overview

Application-oriented design

Magnetic chokes from Tridonic are available in single or multi-voltage versions. With up to three voltage taps in the OM family and up to five in the OG series there are major benefits for luminaire manufacturers because luminaires equipped with these chokes can be used for different mains voltages in different countries.

Chokes with pulse taps are optimised to operate in conjunction with pulse ignitors from Tridonic. These chokes supply very high ignition energy and are also designed for high ignition voltage, resulting in high levels of reliability. Chokes with power taps are suitable for street lighting that switch at certain times to energy-saving settings.

Chokes with double insulation for safety class 2 luminaires have compact designs because Tridonic uses high-quality insulation inside the core. All the versions have a reversible thermal protector rated at 155 °C and a thermal cutout that triggers at 214 °C. The cutout is located in the chokes to ensure reliable thermal contact and rapid triggering.
 

Design for long life

Because of their high-quality insulation material, coil core and copper wire, chokes in the EC, OM, OF and OG 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

The consistently high quality and reliability of magnetic chokes from Tridonic 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.
 

Type series EC

Because of their small dimensions (41 x 31 mm) , magnetic chokes of type series EC are particularly useful if only chokes have to be installed in small cross-sections, such as tube systems. The range covers the operation of high-intensity discharge lamps with wattages up to 150 W. EC units are available with a core length of 90 to 160 mm and with either screw or plug-in terminals.
 

Type series OM

Magnetic chokes in the OM series are suitable for operating mercury vapour lamps, sodium lamps and metal halide lamps with wattages from 35 to 400 W. Their compact design makes them ideal for stylish luminaires. The plug-in terminals enable connections to be made quickly and reliably; voltage taps are also easy to select. Versions with various footplates and different mounting options are also available. The cross-section of the OM series is 65 x 47 mm for core lengths of 30 to 150 mm.
 

Type series OF

OF chokes are available for wattages of 250 and 400 W. With a core length of 40 to 90 mm and a cross-section of 82 x 57 mm, this series is positioned between the OM and OG series. Equipped with robust screw terminals in the coil head, the OF chokes are excellent for compact luminaire designs for the abovementioned output range.
 

Type series OG

Chokes in the OG series are suitable for high-intensity discharge lamps in the high-wattage range from 250 to 3,500 W. With a width of 107 mm, a height of 78, 90 or 106 mm and core lengths between 30 and 210 mm, the OG units are designed for high efficiency and low self-heating. The screw terminals are suitable for wire cross-sections from 1 to 4 mm² and from 1 to 6 mm².
 

Standards and approval marks

Magnetic chokes for HID lamps 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).
