- 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.
- Q: The difference between lighting transformers and control transformers
- The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.
- Q: How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
- General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
- Q: The transformer zero line has broken, has the result to the household illumination circuit?
- No, the zero line of the transformer doesn't go through the zero line of the transformer. It is a star connection, and the center point is zero line
- 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: How many A leakage protection switches are used in 5000VA lighting transformers?
- Secondary current =5000VA/220=22A, you can select the 32A leakage protection switch.
- 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: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
- So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.
- Q: Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
- If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.
