Q: Power supply to the Mori Chong 86N power supply 24-70 volts At present, the use of a 350-watt 50V switching power supply, the maximum current of 7.3 Motor dial selection current 6.3A, short-term operation, heat is not large At this point the switching power supply fan does not turn - is not long-term operation or power to increase the heat when the fan will start? Or are the fans running anyway? So that is the switch power supply cooling fan is broken?: Look at your fan a few lines, two words, do not turn is bad, or broken

Q: What is the component stress in the switching power supply?: Component stress, including voltage stress, current stress, temperature stress, power consumption

Q: Two-wire NPN near switch, switching power supply, and how to connect with Mitsubishi PLC?: You can not use the switching power supply, direct use of PLC input point

Q: 12V switching power supply, which brands through 3C certification?: Now basically is not the cottage products are 3C certification it They are not allowed to recommend or choose the manufacturers of products are generally more insurance Canada is the Great Wall is very good

Q: How to transform the switching power supply, the original AC 220 input into DC 84-100 input output unchanged: It is difficult to change, you can consider the use of ready-made DC-DC converter

Q: What is the use of transformer shielded grounding in switching power supply?: Transformer plus shielding is to prevent electromagnetic interference. Because switching power supply switching frequency is very high, the transformer is a source of interference, shielding it to prevent interference with other components.

Q: Switching power supply how to repair: First observe the power fuse is damaged. If the fuse is damaged, can not rush to replace, you must first check whether there is a short circuit power phenomenon. Method: With the multimeter of the electrical resistance test after the end of the power fuse (test point one), the normal resistance should be more than tens of kilo ohms, such as resistance is zero, then there is AC short circuit phenomenon. In addition, we should also focus on checking the power of the AC filter capacitor is damaged; the same time if there is a varistor, it should also check the resistance. As the above test results are normal, we should then detect the power supply of the four rectifier diodes (test point two). In the normal state, the diode forward resistance of the number of k (with a multimeter × 1k block test), reverse resistance close to infinity. If you find that the test results are not normal, you need to replace. Along the investigation down, and then to do is test the DC resistance of this part of the power (test point three), the normal resistance is also a few k, such as the resistance is zero, then there is a DC short circuit. DC caused by the reasons for more short circuit, such as filter capacitor short circuit damage, power oscillation tube damage, oscillation manifold and the external circuit part of the damage may cause short circuit phenomenon. In this case, it should be noted that before replacing the power oscillation tube, you must determine the oscillation manifold and the external circuit is normal, otherwise it will cause damage to the power supply again.

Q: I went to the hardware store and mobile phone shop asked the next, said that there is no such thing: Personal recommendations do not buy, directly connected to the line with a plug switch to control the cat's power switch.

Q: Switching power input is marked with 220V AC, 36V output, but the actual input voltage is 238V, the output of the switching power supply affect it? Will it damage the switching power supply? Do not know the reason is not the voltage, power after a period of time (10 minutes), the switch power suddenly no output, and the display is not bright, switching power is not already broken? Guiqiu prawn to the doubts!: Switching power supply without output, usually two problems, the first is the switching power supply is broken, the second is the switching power supply output overload, power overcurrent protection or overheating protection, the former need to repair, the latter to remove the load off 220V input Voltage after 5 minutes and then on the 220V to return to normal. The input voltage of 238V is also within the allowable range of the switching power supply, regardless of this.

Q: When switching power supply is the most efficient: This is the design of the time according to the different needs of customers set Generally should be in the 80% load, rated input, a certain temperature under the circumstances to obtain the highest efficiency Specific reference to the power supply specifications
