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.

Q:The difference between lighting transformers and control transformers: Lighting transformer voltage is generally rated by a group or two setsControl transformers have many levels of output 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: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:What type of low voltage transformer should be adopted for safety lighting power supply?: We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!

Q:How many A leakage protection switches are used in 5000VA lighting transformers?: According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.

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:How to calculate the rated capacity of small transformers for lighting purposes?: Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.

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?: Now is the three standard power supply, fire, fire and a single, zero line is three 220V, the fire is 380V. 40W lights can be 25.

Q:How is the lighting power of the 380V transformer calculated?: Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.
