China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Light ballast TW value should be as high as possible, and the winding temperature rise,Δt should be as low as possible, i.e. TW value and delta T value, indicating better quality of the ballast. General good ballast tw=130 Δt is less than or equal to 60 (3) for high strength gas discharge lamp inductance ballast, choose as far as possible with the original logo products, this sign is to indicate internal ballast has thermal protector, inverted triangle winning three points in practical application is indicating ballast surface is the hottest Celsius temperature value, generally for 140 ~ 160. With this sign of ballast, when the lamp or the boot device is damaged (generating abnormal state), the thermal protector will automatically act, which can ensure the safety of the ballast and lamp use.

 

(a) electronic ballast of marking the content is complete, mainly with the Chinese name of the manufacturer or seller; rated supply voltage and frequency; lamp equipped with the specifications, power, the number of lamp; wiring diagram; terminal connecting wire cross-sectional area; TC value (the maximum case temperature); U-OUT value (the output end maximum working voltage); power for numerical and CE certification mark (should have corresponding to the enterprise certification number)

 

(b) electronic ballast TC values to bid higher, that high temperature environment ability, general TC is more than or equal to 65 DEG C, when the TC is more than or equal to 70 DEG C belongs to the quality good product.

 

(c) electronic ballast U-OUT value (output maximum working voltage) should be subject to appropriate, to cooperate with T8 36W and the following specifications and below T5 24W specification lamp electronic ballast, U-OUT is less than or equal to 300V. For T5 28W, T5 35W with the lamp and electronic ballast for T8 58W lamps, U-OUT value should be (300V ~ 450V), buy the fluorescent light ballast, do not install, should carefully look at the sign on the ballast and read the installation instructions, in accordance with the provisions of the logo or specification requirements of wire connecting with suitable sectional area the lamp and ballast, connected by wiring diagram on the sign, the appropriate selection of lamp tube parameters according to the sign, found that both ends of the lamp tube is not bright red, jump, lamp should be replaced in a timely manner, to prevent the occurrence of ballast burned insecurity, in cleaning and maintenance should pay attention not to ordinary combustible materials, such as paper, a rag, the omission of the ballast, so as to avoid the occurrence of safety problems caused by overheating of the ballast, do not use a damp cloth to wipe the fluorescent light ballast, to avoid electric shock.
