Q:What is the difference between a mobile power supply and a power adapter?
Mobile power supply capacity is generally 4000-12000mAh, is a portable external battery.
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
Q:Is the inductor inductor
However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.
Q:How to choose the high quality inductor?
So in the selection of inductors, we have to pay attention to it: first, the higher the value of Q.
Q:Inductor and inductor coil is not a concept
When an electric current passes through the coil, a magnetic field is created around the coil
Q:Why inductors do not consume electricity
When connected to AC inductance, different charging and discharging, does not consume power,
Q:Why use inductance
The basic function of inductive argument: effect of filtering, oscillation, delay, wave trapping image:
Q:Power adapter can be used when the charger
Second is INPUT (input), in China is generally 100-240V~50-60Hz, which shows that it can work under the normal voltage 100V-240V
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
Q:What is the substitution principle of inductance?
Inductor has a certain inductance, it only hinder the current changes
We are a focus on the production of switching power supplies and power adapters and other power products for high-tech enterprises. Shenzhen power adapter, power adapter manufacturers, switching power adapter, switching power supply manufacturers, charger manufacturers, USB power adapter, 12V power adapter
