Q:What is the difference between DC regulated switching power supply and linear power supply?
Switching power supply: high efficiency, small size, inertial components (inductance and smooth capacitance, etc.); Traditional power supply in turn is it, but the traditional power of the biggest advantage is the small noise, harmonic interference is small.
Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera?
Most of the time with seven infrared one machine, the nearest infrared machine 15 meters, farthest infrared one machine 110 meters. Cloth RVV2 * 1.5 power cord
Q:Switching power supply 220 / 24V input break can be frequent power off
Design has a project, but look at your off time.
Q:How to check the switching power supply leakage current
60601 or 60950, third line class I or two line class II, but no matter how! General market has a special test switching power leakage current tester, you can check the Internet, because I have used before But the manufacturer model forgot.
Q:Is switching power and transformer the same thing?
This is not a matter of time, the switching power supply is to control the power supply, the transformer is to change the size of the voltage, the transformer in the case of power to control the voltage.
Q:Give you a switch on how to look at it is isolated and non-isolated?
General low-voltage direct current is mostly non-isolated, high-voltage communication for the isolation
Q:Find the correct use of this constant voltage constant current switching power supply, and the current adjustment method
Constant current type switching power supply, if you want to test its load regulation rate, then first you have to test its output maximum voltage (rated voltage). Whether the constant voltage or constant current output of the switching power supply should have a rated output voltage and rated output current. Rated voltage current and product of course is its rated output power.
Q:12V7A motorcycle battery can not use 14V3A switching power supply charge
Can be used, but can not often use, because: 12V7A battery suitable for the charging current of 0.7-2.1A, 3A current slightly larger. But if you insist on the use of a small change, do not change the original switching power supply, only need a series resistance, resistance size of about 1 ohm, power of 5 wirewound resistors, so that the output current can be controlled within 2.1A, You can also ensure that the battery can be fully charged.
Q:Led switching power supply used in what place
Switching power supply used in the LED driver, the high-end switching power supply, low-end general resistance with the buck circuit can be.
Q:Switching power supply, what is the difference between the charger
Chargers usually refer to a device that converts alternating current into low voltage direct current. And the switching power supply is also the exchange of DC.We are now using the mobile phone charger are generally switching power supply (the advantages of small size, light weight, high efficiency.) Before the old phone with some of the charger is not switching power supply it Inside the transformer transformer and then rectifier filter (because it is used in the transformer, so the volume to be bigger, a little cumbersome, less efficient).
