Q: The main function of the communication switching power supply is: Communication switching power supply is the driving force of the communications industry, in the telecommunications network plays an irreplaceable role, with an unparalleled important basic position. Communication switching power supply is the heart of the communication equipment system, even if the instantaneous interruption is not allowed, because the communication switching power supply system DC power supply interrupt failure is catastrophic, often will cause the entire communication station (station) and communication network all Interrupted and paralyzed. Communication switching power supply is an indispensable and important part of the telecommunication network. It is a cornerstone and background guarantee of a complete, large-scale and complex communication network such as exchange, transmission, data, information, business and intelligence. Therefore, the direct relationship between the communication and switching power supply To the entire network of stability, reliability and smooth, and communication switching power supply due to high efficiency, small size, light weight, etc. are widely used in the communication equipment power supply

Q: What is the output voltage of the no-load? What is the load output voltage?: Power supply test As a source of personal computer power, but also with the progress of personal computers and change. From the previous 100W AT power supply to today's 450W or even higher ATX power supply, not only the power in continuous climb, the output current is also increasing, +5 V output current has more than 30 amps. Since the announcement of the ATX2.01 power supply standard in January 1998, after the production of power are compatible with this standard, but the output voltage of each voltage is increasing. We use the ATX switching power supply, the output voltage of + 12V, -12V, +5 V, -5V, +3.3 V and several different voltage. Under normal circumstances, the above-mentioned several kinds of voltage output range allows the error is generally within 5%, as shown in the table below, can not have too much range of fluctuations, or prone to crash data loss situation. Standard voltage value Wire color Minimum voltage Maximum voltage value + 5V red 4.75 5.25 -5V white -4.75 -5.25 + 12V Yellow 11.4 12.6 -12V blue -11.4 -12.6 + 3.3V Orange 3.135 3.465 Power plug on the motherboard ATX power output connector ATX power supply 20-pin output voltage and function definition table Pin Name Color Description 1 3.3V orange +3.3 VDC 2 3.3V orange +3.3 VDC 3 COM black Ground 4 5V red +5 VDC 5 COM black Ground 6 5V red +5 VDC 7 COM black Ground 8 PWR_OK Gray Power Ok (+ 5V & + 3.3V is ok) 9 5VSB Purple +5 VDC Standby Voltage (max 10mA) 10 12V Yellow +12 VDC 11 3.3V Orange +3.3 VDC 12 -12V blue -12 VDC 13 COM Blue Ground 14 / PS_ON green Power Supply On (active low) 15 COM black Ground 16 COM black Ground 17 COM black Ground 18 -5V white -5 VDC 19 5V red +5 VDC 20 5V red +5 VDC

Q: Switching power supply 10A current, relay 5A current will not burn the relay: Switching Power Supply 10A Current is the ability of the switching power supply to provide current, the relay 5A current is allowed to flow through the relay contacts the maximum current. If the load current does not exceed 5A (to keep the safety factor), it will not burn.

Q: What is the flashing time in the switching power supply?: In order to avoid this spike voltage to make the controller malfunction of the IC will increase the time of about a few hundred nanoseconds, and this time the built-in current limit comparator will not work, Gate output drive will not be Shutdown.

Q: Switching power supply (AC-DC) use notes and tips: ??Fourth, in order to achieve full heat effect, generally installed in the air convection conditions good position or installed in the chassis shell through the shell will heat out. ??5, LED switching power supply factory before the addition of resistive load, if used in capacitive or emotional load, should be preceded by the order to explain ??Sixth, for the dual output symmetrical load, the preferred use of symmetrical output power ??Seven, the power supply FG ungrounded users, hand touch the shell or the output of Ma electrical feeling is a normal phenomenon, floating when the FG on the earth about 110V AC output, which is the power of the internal structure of the decision.

Q: Switching power supply CE certification is probably how much money: Or how much money, there are two or three thousand cheap, you have seven or eight points, of course, the requirements of high, then there are more than ten thousand, specifically look at your needs, look at my name in detail

Q: Four-way monitoring switching power supply is not just a camera circuit can all the way? Or is there a problem with the equipment or line? The camera will appear short-term flash, shaking, black screen phenomenon. Now is the four cameras are connected to the positive and negative, the power is 12V6.3A, plus a small 12V1A power alone access to a camera, the results of a separate shine, the last black screen. The original problem of the camera or a problem, no problem or no problem. And the fault is short, I suspect that the camera problem, but the manufacturers that no problem. Depressed ah! Which a master to help one.: The best is to buy a single 12V1A power supply and then 220V directly to the camera in front, then take 12V1A power supply, so no power attenuation

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!: The actual input voltage at 238V, the output of the switching power supply has no effect, the general input voltage range of 10% or more; "Power after a period of time (10 minutes or so), the switch power suddenly no output, and the display does not light," the switching power supply is already broken

Q: Led lights switching power supply controller how to repair: Check the power input terminals of the rectifier diodes, high voltage filter electrolytic capacitors, inverter power switches and other components are not breakdown, open circuit and damage. But also to see the various components on the circuit board to see whether the appearance of these components without burning paste, with or without electrolyte overflow and so on. With a multimeter to measure the secondary original, excluding high-frequency rectifier diode breakdown, load short-circuit situation, if this time the output is zero, then you can certainly be the power of the control circuit is a problem. Then you can use the static measurement of the corresponding components to check out the damaged components.

Q: 12V, 24V, what else? Is there 110V, 220V? Also divided into DC switching power supply and AC switching power supply?: Single-phase voltage is 220V / three-phase voltage is 380V
