Lighting Product LinePower Conversion

Ballast Standard

IEC (International Electrotechnical commission)

Starting Mode IEC929 : 1990 / 1st editionAC supplied electronic ballasts for tubular fluorescent lamps-Performance requirements 7. Preheat starting mode Need a IC for frequency control 7.1. minimum preheat time : 0.4S maximum effective heating current : not exceed lamp datasheet limit maximum open-circuit voltage : not exceed lamp datasheet limit

Protection Mode IEC61347-2-3 : 2000Particular requirements for ac supplied electronic ballasts for fluorescent lamps 16. Abnormal conditions FAN7710/1 cover without external components a) the lamps or one of the lamps is not inserted.

b) the lamp doesn't start because one of the cathodes is broken c) the lamp doesn’t start although the cathode circuits are intact (de-activated lamp) d) the lamp operates, but one of the cathodes is de-activated or broken e) short circuit of the starter switch, if any

17. Behavior of the ballast at end of life FAN7713 will cover Mandatory claim for T4/T5 Lamp a) asymmetric pulse test, b) asymmetric power dissipation test, c) open filament test
