Q:What is inductance effect
According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
Q:What is the power adapter
The power adapter (also called the external power switch power adapter)
Q:The function of computer monitor power adapter
The first is the model, it tells us manufacturers, Watts and other information;
Q:What is the inductance
skeleton skeleton refers to the winding coil bracket. Some of the fixed volume inductor larger or adjustable inductor (such as oscillation coil, choke etc.)
Q:The value of the inductance is determined by what
The method of reducing the Q value can be to increase the resistance of the winding or to use the magnetic core with large power consumption
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
Q:What is the difference between the power adapter and the power converter?
The power converter is mainly used to convert a form of socket into a different form or socket, as well as mobile phone charging, electric vehicles are also a class of power converters
Q:What is the substitution principle of inductance?
If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current constant when the circuit is disconnected.
Q:What are the main parameters of inductance?
The inductance of the inductor, the number of turns of the primary coil (turns), the winding method, the material of the core and the magnetic core, etc.
Our products have perfect protection functions, which includes complete over-charge, over-release, over temperature, over-current and over-voltage and have stable, safe and reliable performance.
