Q: How many power illuminator can 5Kva 36V transformer drive?: The load capacity of the transformer is 70% of its nominal power, so it is concluded that the transformer you provide can drive the 3.5KVA 36V lighting appliance (which is used in normal condition and environment)

Q: What type of low voltage transformer should be adopted for safety lighting power supply?: Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.

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: 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: 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: Does the lighting work properly? Doesn't that power equipment start voltage unstable?: Power lines and lighting lines are connected to the same transformer, without affecting the use of a transformer power users, lighting and power are connected together.

Q: How is the lighting power of the 380V transformer calculated?: With a light bulb with 4KVA load, the premise of the distance can be Mrs. face light bulb, dark can light the best load, 3KVA bulb brightness

Q: Can the 500 volt lighting transformer be changed into an electric welder?: The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft

Q: Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?: 220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
