Q:How to test the power adapter
such as an adapter with 5V and 1A, then it is 5V * 1A = 5W, 5V = 5 and 5W 25 square in Europe, select 5 Euro 5 Watt dummy resistance test adapter performance, such as whether overheating after output voltage fluctuation phenomenon
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:What is the role of inductance in the power supply
AC resistance: in the AC circuit, the inductance will have an impedance, that is, XL, the current of the circuit will become smaller, a certain degree of obstruction to the exchange.
Q:What is a power adapter, what is the use of
The utility model is widely used in the equipment such as the telephone master machine, the game machine, the language repeater
Q:Inductance works?
When the current in the coil is changed, the magnetic fields around also produced corresponding changes, this change can make the magnetic field coil induced electromotive force (EMF is used to represent the terminal voltage of the active element of ideal power source, this is the self).
Q:The role of inductance in the circuit
Any of the current in the circuit, will produce a magnetic field, the magnetic flux and the circuit.
Q:What are the main parameters of inductance?
There are five important parameters of inductance: inductance, allowable deviation, quality factor, distributed capacitance and rated current
Q:Inductor and inductor coil is not a concept
So the inductor and inductor coil can be considered the same, some different
Q:What is the difference between a power adapter and a voltage regulator?
Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage
Q:Inductance is the sensor?
Inductance is an attribute of a closed loop formed by the winding of a wire
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
