Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?

See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W

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:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?

The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, filament, cold resistance and simultaneous startup factor, it is better to choose the 400VA transformer

Q:Why should lighting transformers be used in factories and mines?

There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.

Q:How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?

The key is that the 220V terminals and 0 can not provide 1000VA capacity?

Q:How many A leakage protection switches are used in 5000VA lighting transformers?

Line lighting transformer is suitable for AC circuit of 50~60 (Hz). It is widely used in electronic industry or industrial and mining enterprises, mechanical equipment, general circuit control power supply, safety lighting and indicator light power supply.

Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?

Generally, the power of the transformer is the apparent power, and the light bulb is the active power, and the power matching is taken into account.

Q:What's the function of the lighting transformer?

Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.

Q:Can the 500 volt lighting transformer be changed into an electric welder?

The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.

A set of coils in a autotransformer having one tap that does not function as a barrier. Or, the two sets of coils are attached.
