Q:The difference between lighting transformers and control transformers: In principle and construction, there is no difference between the two.The only difference is that the secondary coil output voltage is different.

Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)

Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?: The bulb is used in the two luminescence tube combined type lamp holder, the calculation process is very complex. Different combinations, the secondary voltage is different. Because it is a DC ignition, but also consider the efficiency of rectification, but the total power is constant.

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: Double winding type safety isolating transformer load end and the power supply terminal is not connected, is safe, and autotransformer primary winding of a share, it is directly connected with the power supply end of the power, not safety.

Q:What type of low voltage transformer should be adopted for safety lighting power supply?: We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!

Q:What's the function of the lighting transformer?: In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!

Q:Power and lighting transformers, lighting quality will be affected much?: The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.

Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body

Q:Why can't autotransformer be used as transformer for safety lighting?: The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous

Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?: It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.
