Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.
Q:Why should lighting transformers be used in factories and mines?
There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
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.
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 40W bulbs can be brought into the 1000VA lighting transformer?
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: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:The difference between lighting transformers and control transformers
A control transformer is a low voltage appliance, usually used as a power supply or part of a lighting for the control of electrical equipment such as machine tools. There are usually two different voltage outputs,
Q:How to calculate the rated capacity of small transformers for lighting purposes?
If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.
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: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!
We not only respond to current requirements, but we also anticipate their emerging needs. We warmly welcome customers from all over the world to contact us and establish business relationships for a better future.
