FAQ

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)
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
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.
Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.
Why is elevator lighting transformer installed?
3 a power outlet shall be provided at the bottom pit.4 the cables and wires laid in the hoistway shall be flame retardant and damp resistant, and shall be protected by a nonflammable wire, conduit, or wire slot, with no use of wires, conduits, or wire slots made of combustible material.5 an elevator attached to a building whose wiring, materials and methods and electrical components used shall take into account the effects of climatic conditions and shall take waterproof measures.Lighting transformers in order to obtain 36V voltage
Why can't autotransformer be used as transformer for safety lighting?
When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!
1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
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?
