Product Description:

Feature

 

Integrating the advance duplex winding compensation mode¡¢non-contact Switch and microcomputer controlled regulating technology. It has the features of high efficiency and energy-saving¡¢fast adjustment¡¢three phase automatic balanced no mechanical malfunction or carbon brush wearing, also with the functions of delay¡¢under/over voltage alarm and protection.

  • Adopting the advanced duplex winding compensation technology which ensure little waveform distortion.

  • Adopting one-chip computer to control the thyristor and shifting combination for timing compensation adjustment enable it to realize the fast non-contact  adjustment. Strong instantaneous overload capacity makes it available with various loads

  • Adopting one-chip computer split-phase control, it has the functions of delay starting-up, three-phase automatic balance adjustment, display¡¢alarm and protection of open-phase, overrun and malfunction etc.

Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
You must know the quantity and power of the lamp to determine the transformer
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
The sectional area of the wire can be calculated according to the electric power formula. The current required by the wire is calculated, and then the reference to the national standard "500 volt copper core insulated wire, long term continuous load allowable ampacity meter" is selected.
Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.
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:How many A leakage protection switches are used in 5000VA lighting transformers?
Line lighting transformer is suitable for AC circuit of 50~60 (Hz). It is widely used in electronic industry or industrial and mining enterprises, mechanical equipment, general circuit control power supply, safety lighting and indicator light power supply.
Q:Why is elevator lighting transformer installed?
Is that the kind of 220V change 36V ah, if it is that kind of thing, I think it should be for security reasons. After all, 36V is a safe voltage. The damage to humans is slightly smaller than that of 220V.
Q: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.
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
Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A
Q:Power and lighting transformers, lighting quality will be affected much?
The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.
