- Q: How to identify the computer motherboard and switching power supply, restart, hard disk plug
- 3, PW LED is the power indicator, + is the positive, - or no sign there is the negative side, this can not be inserted, plug the power light is not bright. Similarly, Power sw is the power switch, also marked with positive and negative, but this is the plug is not a big relationship. Rest sw is to restart the pin, there are positive and negative, with the same as the Power sw, plug the anti-no relationship. Next to the English speech is a small speaker pin, usually dead feet and side by side.
- Q: I have a 12V3A switching power supply. From 0V to 12V, 2V3V can start. Want to carry out voltage regulation. How to do? If you use the potentiometer to connect the kind of potentiometer. I connected to the permanent magnet three brush motor is the car with the wiper motor, the motor high and low speed adjustment. Originally wiper motor there are two blocks. Richer speed adjustment.
- With a potentiometer to the 12V3 amp DC motor speed, the voltage drop in the potentiometer (variable resistor) on the energy consumption of large (and fever), you that 12V3A switching power supply from 0V, 2V, 3V - -12V continuous adjustment
- Q: Switching power supply 10A current, relay 5A current will not burn the relay
- If it is regulated switching power supply will not, if it is constant current switching power supply will be
- Q: Wireless communication room in the combination of switching power supply and integrated switching power supply and the difference between the respective functions?
- The so-called combined switching power supply, there are a number of independent switching power supply through the switch with control cabinet control, according to the size of the load to the wireless communication equipment power supply, load can provide two or more switching power supply, Taiwan power supply. And the integration of the power he is a wireless communication equipment to form an integrated device, can only have the equipment to accompany the switching power supply. After the switching power supply is damaged, the communication equipment than to stop working, the combination of power can be changed for other power supply
- Q: Switching power supply TL431 what role, I did not find the circuit in 431 the corresponding circuit
- widely used in the soft-start capacitor: generally connected to the switching power supply on the base of the switch to prevent the power,
- Q: Working principle of small switching power supply
- Small switching power supply works is to control the switching transistor through and turn off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. Switching power and linear power compared to the cost of both the output power increases with the growth, but the growth rate of the two different. Linear power costs at an output power point, but higher than the switching power supply, which is called the cost of reversal point.
- Q: Drawings indicate DC-DC switching power supply can be replaced with AC-DC switching power a?
- DC input switching power supply and AC input switching power supply is not interchangeable. But if you have the knowledge of this circuit, after the transformation of the circuit can be interchangeable. Principle: AC input switching power supply, the AC input rectified filter voltage and DC input switching power supply DC input voltage of the same.
- Q: What is the industrial switching power supply
- Switching power supply is divided into civilian-grade industrial grade military grade of course different levels of power, safety requirements, performance requirements, insulation level and so on are not the same requirements, the same level of power also look at what work environment, require different power level The standard is different. Need power to find me
- Q: Car cd with the battery all right, with a switching power supply speaker has a buzzing sound
- Need to use the power supply, switching power supply impurity
- Q: Today encountered a switching power supply, independent of the 220v into, 12v out, after opening and ka3842 see the sixth foot of a resistor and a diode at the obvious phenomenon of burning, I measured with a multimeter has 300v, but a flash Flash After the resistance, the low pressure at a light is flash, no output,
- 3842 6 feet is the chip output pin, if burned there, it is likely that the chip and switch are broken But the power output there is voltage, although unstable, indicating that the chip and switch is still working. You can test the chip 7 feet voltage is stable, if the stability of the power supply is likely to low side problems. If the voltage is unstable, when the high when the more difficult to repair this, it is likely to start from the chip.
