- 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: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: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
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, filament, cold resistance and simultaneous startup factor, it is better to choose the 400VA transformer
- Q:Why should lighting transformers be used in factories and mines?
- There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
- 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?
- Connect 220V method, FireWire 220V terminal, zero line 0 terminal, 380V terminal is not connected.Connect 380V method, A phase 380V terminal, B phase 0 terminal, 220V terminal is not connected.
- 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?
- 1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.
- 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: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.
