A comprehensive range of Wire Wound Transformers from Tridonic for use with High Pressure Sodium, Metal Halide and High Pressure Mercury Vapour Lamps. These magnetic choke ballasts (not including mercury vapour) all require an ignitor to fire them, but common to all is extremely low power consumption, compact windings and minimal magnetic leakage field, resulting in very low noise.
These robust transformers guarantee MH, HPS and HPMV lamps operate according to the manufacturer's specifications and achieve their maximum luminous flux.
Utilising these transformers results in a high level of cost and energy efficient HID lighting. Small, compact dimensions and high grade materials compliment the benefits of these units. The use of high quality insulation material, coil core and copper wire means these chokes achieve a service life of up to 100,000 hours; that is 10 years of constant use at a winding temperature of 130°C. A change in temperature of 10°C down or up leads to a doubling or halving of the life of the unit. These OM Chokes are for use with 35W to 400W HID lamps and come with push fit or screw in terminals.
