Q:24V 1A switching power supply how to output 0-10V I <1mA adjustable signal ah
You call the power of external control, your switching power supply voltage is fixed, it can only 0-10V, control 0-24V, the current to buy a Hall sensor, corresponding to the output 1A,
Q:Is the switching power supply connected to the power supply voltage is too low on the switching power supply it?
The input voltage below the allowable range will reduce the output power of the switching power supply, the stability of the output voltage will be poor, adjust the stability of the tube will rise, if the input voltage is below the allowable range of switching power supply is not working or stop jobs.
Q:12V switching power supply, which brands through 3C certification?
Big brands have, sailing, the Great Wall, technical exhibition ..... N more ...
Q:Charger, switching power supply, power adapter these three different?
Switching power supply is 220V voltage into a low-voltage DC method, he is different from the traditional power frequency transformer. The use of this switching voltage technology is called switching power supply, charger and power adapter are currently used in switching power supply technology. Charger specifically refers only to the battery charge thing, generally with charging indicator, such as battery car charger. He can not be called an adapter. An adapter is something that provides power to a device. Such as a power adapter for a liquid crystal display, and a power adapter for the printer. Can not be called a charger. There is another thing. For example, the phone that stuff or laptop that is used, now called the adapter. But we call him a charger. And the top two names have appeared. So when he called the charger when charging, if finished over
Q:Two-wire NPN near switch, switching power supply, and how to connect with Mitsubishi PLC?
Using the source PLC. Close the switch to the common (COM) and input X
Q:Note the operating conditions of 220V voltage and the order of switching power supply
Off the electricity ------- pull the security ground ------- Li Ming signs pull off the line ------ operation Check the operation is correct to complete the task ------ demolition of insurance grounding ------- remove the warning card pull off the line ------ power
Q:Switching power supply (AC-DC) use notes and tips
10, switching power supply in the factory to 100% full load aging, the general use of power control within 80% or in accordance with the requirements of the instructions. According to the temperature curve to develop power efficiency. The general temperature is increased by 10 ° and the capacitance life is reduced by half.   11. Before using the switching power supply, make sure that the input voltage specification (110VAC or 220VAC, 24VDC or 48VDC ...) matches the nominal value of the switching power supply used.
Q:Switching power supply management IC FB, CS, DEM specific what role ah
FB is the voltage feedback, CS is the current feedback, DEM do not know, it is best to send the chip, the different circuit function is not the same. Such as constant current output circuit FB is the current feedback!
Q:Who can help me choose a switch power supply model 220V AC / 10V DC
I help you choose a switch power supply model 220V AC / 10V DC output full power.
Q:Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,
This is a single-ended flyback switching power supply circuit, in this switching power supply, T2 is a high-frequency transformer, the role of voltage conversion, R11 is the starting resistance of U1, the input voltage of 85 - 2-265 AC, the choice should be in the 1--2W, 150 - 330K resistance between, usually need to use multiple resistors in series, otherwise it is easy to damage. R12 is the current limiting resistor of the switch, but also U1 overcurrent current detection resistor, the output short circuit when the voltage drop on the resistor will become high, U1 protection to stop the output drive signal. D6 is the transformer provided to the U1 supply voltage rectifier. C2 is the main filter capacitor, usually with electrolytic capacitors, voltage is greater than the maximum voltage input of 1/3, the capacity of about 1W / micro-law output. Q1 is the FET, is the switch tube. Generally also mos. D5 and R7, C5 are connected to the transformer primary to form the transformer spike voltage absorption circuit. When the switch is turned off, the moment the transformer will have a very high induced voltage generated, this circuit can be absorbed by this spike voltage (or is limited to a safe Of the range). Also called DRC or RCD spike voltage absorption circuit. U1 is the switch tube drive circuit, here should be a PWM integrated circuit, also known as pulse width modulation, is the English "Pulse Width Modulation" abbreviation, referred to as pulse width modulation. U6 is a photocoupler,
