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: Who knows how big transformers and lines the 36V transformer uses in lighting?: How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.

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 to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)

Q: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)

Q: 3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?: The bulb is used in the two luminescence tube combined type lamp holder, the calculation process is very complex. Different combinations, the secondary voltage is different. Because it is a DC ignition, but also consider the efficiency of rectification, but the total power is constant.

Q: Does the lighting work properly? Doesn't that power equipment start voltage unstable?: It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.

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: How to calculate the rated capacity of small transformers for lighting purposes?: But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.
