Phase voltage:220V Single-phase:220V Line voltage:380V
Output voltage accuracy
1-5%(can be adjusted)Frequency:50HZ/60HZ
≥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?
- But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""
- Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- Voltage x current = power, in general we are using the total power of 2/3, you can press this type of calculation, if the installation of electrodeless lights, the line should be separated,
- Q:What transformer can be used in a safety voltage lighting transformer?
- Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.
- Q:How many A leakage protection switches are used in 5000VA lighting transformers?
- AC circuit transformer for lighting lamp is suitable for 50-60Hz, is the power supply with safety shell low-voltage safety lights, can choose 220V or 380V power supply input voltage: 0V, 220V, 380V, 0V, 6.3V, output voltage: 12V, 24V, 36V.
- 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: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?
- The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive 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:Power and lighting transformers, lighting quality will be affected much?
- Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer
