- 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: The transformer zero line has broken, has the result to the household illumination circuit?
- The lighting circuit mostly 3 phase unbalanced load, there will be zero drift, zero if the transformer line is broken, part of the lighting circuit to form a series of equipment in the case of two-phase circuit, circuit voltage is decreased and the lighting brightness is not enough, circuit voltage increases, the lamp burned;
- Q: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- What you think? Your light is 220V, right. Over 36V, it's better not to live with electricity unless there is good protection
- 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: How is the lighting power of the 380V transformer calculated?
- The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator
- 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: 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: Power and lighting transformers, lighting quality will be affected much?
- Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer
- Q: What's the function of the lighting transformer?
- Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.
- Q: Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- Line light for safety light, voltage 24 volts and 36 volts, pay attention to the bulb and transformer voltage matching.
