Q:What is the role of switching power supply is specific?
Open on the electricity, turn off no electricity, and then fine that is open after the internal power supply channel can work.
Q:What is called switching power supply? Such as commonly used circuit
The use of electronic components to control the power switch output, of course, than I said more trouble. Such as the general TV computers are used with the switching power supply.
Q:12V switching power supply, which brands through 3C certification?
Big brands have, sailing, the Great Wall, technical exhibition ..... N more ...
Q:Isolation switch power supply and non-isolated switching power supply advantages and disadvantages,
Isolation type: Advantages: before and after the isolation, after the level of the earth without dangerous voltage, the output voltage can be equal to the input voltage or can contain a range of input voltage Disadvantages: larger, or the same size of the power smaller Scope of application: the occasion of electricity supply (such as computer power); signal detection to isolate the collection of occasions (such as electrocardiograph)
Q:Switching power supply COM how to connect
Switching power supply COM is always grounded, not a description of it?
Q:Switch power jumper do not know which one which then do?
Motherboard if it is old-fashioned 9-pin is the left side of the HDD LED left and then the left is the POWER LED lower right is restart the rester right power Not the old 9-pin, then the board marked on the plug can be a If it is green black line green line red line red line red line is red line is red!
Q:Switching power supply, 2SC3320 switch tube is always burned
The power switch works in the switch state, the cause of its damage, in addition to over-current over-voltage, but also taking into account the duty cycle, that is, saturated conduction time and cut-off time ratio.
Q:24-volt switching power supply why leakage
1, the ground has two y capacitors Neutral grounding way connection, (fire --- || --- --- ---| --- zero) In this way if the socket is good grounding is no problem, But the socket ground if the virtual connection, this time on the line with 110V (may be higher and lower) equivalent potential, if the electrical appliances are metal shell ground, it is possible that the entire shell are charged, the pen will be bright, Ma hand.
Q:Switching power supply CE certification is probably how much money
Switching power supply CE certification is not expensive, do a CE certification can be sent to the RoHS certification, the specific cost can provide product information to assess, package rectification, retest not charge, welcome to consult us CNAS laboratory, ID number is the phone, thank you!
Q:How to identify the computer motherboard and switching power supply, restart, hard disk plug
2, HDD LED is the hard disk indicator, the general is the vertical look, + there is a positive side, - or not sign there is a negative side, the chassis is also reserved for such a plug, corresponding to insert the corresponding board can be set The HDD LED lights feet can not be inserted, plug the indicator light is not bright.
