Electrical Ballast is one kind of the ballasts; it is the electronic equipment which adopts electronic technology to drive the electrical light source to produce light. Modern Fluorescent lamps increase to use electronic ballast, compact and small, even can integrate electrical ballast and lamp tube, at the same time, electrical ballast usually can be compatible with starter function, thus it can also eliminate the starter.
Electrical Ballast has obvious advantages to develop the energy efficiency and quality of the lighting system; it is the new international recommended applications products, which is also the future trend. Pay attention to the harmonic content. The new revised “AC-supplied electronic control gear for tubular fluorescent lamps-performance requirements”(GB/T15144－2005) has canceled the class of electronic ballast (Class L and Class H) in the old standard, the harmonic limit should meet “Electromagnetic Compatibility, Limits, Harmonic, Current Emission Limits”(GB17625.1－2003).
At present, there are electrical performance testing and EMC characteristics for electronic ballast testing.
Electrical performance is the basic performance of Electrical Ballast, for Electrical Ballast, mainly has three characteristics testing: Input Parameters Measurement, Output Stably Parameters Measurement and Output Startup Parameters Measurement. Input Parameters Measurement has voltage, current and power, power factor, power net frequency, total harmonic and 0~39 harmonic test. Output Stably Parameters Measurement has lamp voltage, current, power, filament, imported cathodic current, crest factor, oscillatory frequency test. Output Startup Parameters Measurement has preheats time, lamp voltage, lamp current, filament current, guided cathodic current curve and parameter. Lisun combines the latest international and domestic standards of IEC60929, IEC60969, IEC61000-3-2, GB/T15144-20005, GB/T17263-1998 etc and pushes the WT5000 Electronic Ballast Tester, adopts a super-maximal LCD for displaying waveforms and parameters directly. In addition to this, WT5000 Electronic Ballast Tester has expanding analysis for envelop wave.
Besides the electric performance, the electromagnetic compatibility characteristics (including EMI and EMS) test and evaluation of Electronic Ballast is very important, when users use standard compliant ballast, its peripheral electronic devices will not be disturbed, such as computer, wireless phone and a number of professional electronic equipment. Electronic Ballast electromagnetic compatibility test includes surge test, electrostatic test and EMI test. Moreover, ring wave test is also requested by Energy Star in April, 2013. For this, Lisun Group pushed series of EMC test equipments, includes ESD61000-5 Electrostatic Discharge Simulator, SG61000-5 Surge Generator, CSS61000-12 Ring Wave Generator and KH3962 EMI Test System.
Lisun Group’s WT5000 Electrical Ballast Tester and EMC test equipment is widely applied to Luminaries manufacturing enterprise and lab, such as Institute of Testing and Certification India Pvt. Ltd (India), LED shine (Netherland), PT. SHARP SEMICONDUCTOR INDONESIA (Indonesia), TUV Rheinland InterCert Kft.( Hungary), Capital Power Systems Ltd(India) ,Fiberli (Turkey) and etc. The reason why Lisun can win some many customers is because we always practice the motto of right products, right price and right service. Lisun will continue feedback good quality products and superior service in the feature.
