- Q: Switching power supply COM how to connect
- Switching power supply COM is always grounded, not a description of it?
- Q: I do not understand the transformer should only work in the alternating voltage, but the switching power supply to the PWM IC output terminal connected to the primary input PWM IC has been rectified filter DC. Is the PWM modulation obtained by the high frequency of the exchange?
- The transformer in the switching power supply is basically the same as that of a conventional power transformer, except that it has a feedback winding that provides a positive feedback signal to the PWM IC to cause high frequency oscillation along with the primary winding, Winding DC with a large AC component, the high-frequency AC components through the transformer core isolation in the secondary form of a pure high-frequency AC, rectifier filter after the supply of electrical equipment. Because the frequency is very high, compared to ordinary power frequency, switching power supply in the transformer and filter capacitor are greatly reduced.
- Q: Note the operating conditions of 220V voltage and the order of switching power supply
- Power failure - electricity - lock - seal ground - warning signs
- Q: Switching power supply (AC-DC) use notes and tips
- Power Usage Precautions: First, the metal shell Power cord and the shell is generally connected with the ground (FG), to be reliable grounding, to ensure safety, can not be mistaken to the shell connected to the zero line. ??Second, before the installation is complete power test run, please re-check and proofread the wiring on the wiring, make sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current value is correct Before they can run. ??Third, for high-power LED switching power supply, there are three or more than three "+" input terminals and "-" output terminals, in fact they belong to an output electrode, just to make the user easy to connect, and multiple terminals Respectively, in the internal and then together.
- Q: Two-wire NPN near switch, switching power supply, and how to connect with Mitsubishi PLC?
- Two-wire NPN proximity switch, two lines, generally brown, blue. 24V switching power supply. Switching power supply 0V and PLC COM terminal short to form a total OV Then PLC (COM) connected to the sensor blue line, the sensor brown line connected PLC X side Another point I would like to point out. Two-wire proximity switch, regardless of the difference between NPN and PNP, NPN blue OV brown x end PNP brown 24V blue X end
- Q: How to choose the switching power supply frequency?
- Have a few points! The size of the input voltage, the choice of transformer magnetic material, the choice of the main switch tube, there is the overall volume requirements can also be said to want to achieve the power density! For example: low-voltage input, such as 6-160VDC, when the pressure on the tube is not high, the switching loss is not dominant, the frequency can be relatively high,
- Q: What is the use of transformer shielded grounding in switching power supply?
- Internal shielding: between the primary side and the secondary side to increase the winding or copper foil, leads to one end of the original side of the work above the main purpose is to the primary side of the common mode interference signal through the shield back to the source of harassment, if not the shield Layer, there is a common mode interference signal will be passed between the primary winding between the interlayer capacitance to the secondary side, causing the output of the EMI problem. External shielding: in the transformer outside the magnetic core and winding coated with a layer of copper foil, this layer of copper foil to be closed to form a ring circuit. The leakage magnetic field of the transformer is not closed inside the core, but leaks into the external space. In the high frequency application, the strong leakage magnetic field will induce the voltage in the closed loop of the input and output ports, resulting in EMI test results deteriorate. If there is an external shielding layer, according to the principle of electromagnetic induction, the shield layer will induce the current, the formation of the opposite magnetic field, offset the transformer leakage magnetic field effects.
- Q: 12V10A switching power supply in the layout of the line when the longest cloth?
- 12V10A switching power supply with 5 12V2A surveillance camera. General 2 * 1 power line transmission 300 meters is no problem.
- Q: Switching power supply, what is the difference between the charger
- 1, we all know that the electricity is 220V / 50Hz AC, and the computer system components are low-voltage direct current, so the power supply is the protagonist of computer power supply, if the current than blood, then the power is the heart of the computer. After the power into the power, the first through the choke coil and capacitor filter high-frequency clutter and interference signals, followed by rectification and filtering to get high-voltage direct current, and then into the power of the core part of the switch circuit is mainly responsible for DC conversion For the high-frequency pulsating direct current, and then send high-frequency switching transformer buck, and then filter out the high-frequency AC part, so that the computer needs more "pure" low-voltage direct current because the computer power is the core part of the switch circuit, Usually referred to as switching power supply. Turn left to turn right Therefore, the switching power supply is popular on the computer "transformer", the AC power into a fixed DC power supply to the computer components to use.However, the switching power supply and linear power supply is not the same: it first 220V AC change Into the DC, and then through the converter to DC into AC, and finally turn the AC into a DC output. The reason for the conversion to high frequency AC is the high frequency AC in the transformer transformer circuit efficiency is much higher than 50Hz, so the switch Transformers can do very little, and work is not very hot, if not 50Hz into high-frequency switching power supply does not make sense!
- Q: Output + 5V, plus or minus 15V, +24 V, not isolated 15V. Input 85 ~ 220AC, the total power of about 20 watts. I see three kinds of control chip, UC3844 similar products in the most widely used, but the internal non-integrated power tube, peripheral devices are more. VIPER I used the 12, the frequency fixed 60K, so the transformer will be relatively large, PCB also have to do big. I tend to use top223 similar products in almost no use top series, I worry about its stability, and the price of single tube seems to be the highest. These two days the boss will I set down, I hope a master to give pointers. If these three kinds of chips have any other differences also please enlighten, thank you
- TOP and VIPER than: really TOP than VIPER price of your point, but the high frequency of 40K it, in fact, TOP223 can replace the VIPER, you do 20W output looks like TOP223 is not enough because the 223 wide range of input 85-265AC can only do 15W (P or G package), Y package 223Y can do 30W, but have to leave the margin? And 3844 compared to the first two: you can freely choose the appropriate MOS tube, higher operating frequency, a variety of forms of protection. The above is a more obvious difference, the specific or look at the cost of indicators required. You do not know how to use the multi-channel regulator with three? Cross adjustment rate has been a tune! Haha
