Widely used in the fields of post office,store,elevator,hospital,school,publishing house and stock exchange where normal voltage is in need,and also can be used in the factories of large and middle-scale industrial and mining corp,it is very much suitable for some important devices and supporting single machine.

≥98%(Power grade over 50KVA)
The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute
It can last 1 minute at the rated current of two times
Wave form Distortion
No additional waveform distortion
it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
≤1s(in the condition that the external voltage changes is 10%)
- 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: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:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.
- Q:Why is elevator lighting transformer installed?
- Is that the kind of 220V change 36V ah, if it is that kind of thing, I think it should be for security reasons. After all, 36V is a safe voltage. The damage to humans is slightly smaller than that of 220V.
- 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: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:The transformer zero line has broken, has the result to the household illumination circuit?
- When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage
- 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.
- 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:Power and lighting transformers, lighting quality will be affected much?
- First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.
