Q: How many power illuminator can 5Kva 36V transformer drive?: The load capacity of the transformer is 70% of its nominal power, so it is concluded that the transformer you provide can drive the 3.5KVA 36V lighting appliance (which is used in normal condition and environment)

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?: The key is that the 220V terminals and 0 can not provide 1000VA capacity?

Q: Why is the two side of the lighting transformer grounded?: The metal shell transformer grounding grounding protection is called: under normal circumstances is not charged, electrical metal and in the damaged insulation or other circumstances may be charged part (i.e. metal structure and insulation electrical parts part) and grounding wire connected to a reliable way to protect people.

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: The transformer zero line has broken, has the result to the household illumination circuit?: The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.

Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: A set of coils in a autotransformer having one tap that does not function as a barrier. Or, the two sets of coils are attached.

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: What's the function of the lighting transformer?: In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.

Q: How to calculate the rated capacity of small transformers for lighting purposes?: In view of the power [kVA] conversion of each load, multiplied by the amount of consumption, according to the importance of the load, equipment location, voltage statistics, set the load line and load place of plastic case transformer capacity and its connection position. The future load power equipment shall be judged on the basis of prior installation or consideration of the economy in terms of equipment addition, installation, etc..
