Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)

Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?: Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.

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 type of low voltage transformer should be adopted for safety lighting power supply?: Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.

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: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: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:Why is elevator lighting transformer installed?: 3 a power outlet shall be provided at the bottom pit.4 the cables and wires laid in the hoistway shall be flame retardant and damp resistant, and shall be protected by a nonflammable wire, conduit, or wire slot, with no use of wires, conduits, or wire slots made of combustible material.5 an elevator attached to a building whose wiring, materials and methods and electrical components used shall take into account the effects of climatic conditions and shall take waterproof measures.Lighting transformers in order to obtain 36V voltage

Q:How to calculate the rated capacity of small transformers for lighting purposes?: If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.

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?: Voltage x current = power, in general we are using the total power of 2/3, you can press this type of calculation, if the installation of electrodeless lights, the line should be separated,
