- 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: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:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- Generally, the power of the transformer is the apparent power, and the light bulb is the active power, and the power matching is taken into account.
- Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- Connection mode:N circuit breaker is caused by breaker of outlet line of transformer main cabinet.The branch circuit breaker divides the power, the electricity and the lighting power.
- Q:How many A leakage protection switches are used in 5000VA lighting transformers?
- Secondary current =5000VA/220=22A, you can select the 32A leakage protection switch.
- Q:Why can't autotransformer be used as transformer for safety lighting?
- The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
- Q:Can the 500 volt lighting transformer be changed into an electric welder?
- The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft
- 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 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:What type of low voltage transformer should be adopted for safety lighting power supply?
- We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!
Our well-equipped facilities and excellent quality control throughout all stages of production enable to guarantee all of our customers' requirement. CE,RoHS,SAA,C-Tick,MEPS,UL,PSE,KC and ISO 9001 certifications could be offered.
