- Q:How many A leakage protection switches are used in 5000VA lighting transformers?
- It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.
- Q: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
- 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:Is the substation separate from the power and illumination transformer?
- There is only bus in the substation, and the station is connected with the transformer from the bus. If there is no electricity even in the bus, then the substation should not be considered active.
- Q:How many power illuminator can 5Kva 36V transformer drive?
- By formula: P=UI COSAThat is, the transformer capacity is S=UI=5KVAHow big is the COSA?. Look, what kind of illuminator do you use?. Usually take 0.8-0.9It can be calculated that P is about 4KW-4.5KW (general lighting)
- Q:Power and lighting transformers, lighting quality will be affected much?
- The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.
- Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.
- 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 many 40W bulbs can be brought into the 1000VA lighting transformer?
- Voltage x current = power, in general we are using the total power of 2/3, you can press this type of calculation, if the installation of electrodeless lights, the line should be separated,
- Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
- Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.
