Q:What type of low voltage transformer should be adopted for safety lighting power supply?
In general, indoor transformers are used in general practice
Q:How many A leakage protection switches are used in 5000VA lighting transformers?
AC circuit transformer for lighting lamp is suitable for 50-60Hz, is the power supply with safety shell low-voltage safety lights, can choose 220V or 380V power supply input voltage: 0V, 220V, 380V, 0V, 6.3V, output voltage: 12V, 24V, 36V.
Q:Can the 500 volt lighting transformer be changed into an electric welder?
The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.
Q:How many power illuminator can 5Kva 36V transformer drive?
Of course, if you want to bring more is not impossible, but depends on the working conditions, the actual power = nominal power, short time use (to ensure that the transformer temperature rise is not too high) is also available
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:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.
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: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.
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.
