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.
Three-phase four-line system phase voltage:220±20%

Output voltage accuracy
2-5%(can be adjusted)Frequency:50HZ/60HZ
≥98%(Power grade is 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
≤1.5s(in the condition that the external voltage changes is 10%)
- 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: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:The transformer zero line has broken, has the result to the household illumination circuit?
- The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.
- 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: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:Who knows how big transformers and lines the 36V transformer uses in lighting?
- 380V-220V/36V transformers, commonly known as safety transformers or line transformers, are mainly used for lighting in shop equipment and mobile lighting for inspection and maintenance. Their power is 50W, 100W, 200W, 300W., and their line size is determined by power!
- Q:Why can't autotransformer be used as transformer for safety lighting?
- The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
- Q:Why is the two side of the lighting transformer grounded?
- The metal shell transformer grounding grounding protection is called: under normal circumstances is not charged, electrical metal and in the damaged insulation or other circumstances may be charged part (i.e. metal structure and insulation electrical parts part) and grounding wire connected to a reliable way to protect people.
- 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:What transformer can be used in a safety voltage lighting transformer?
- 220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.
