Q: A DC / DC switching power supply input with UC3843 is a 24V power supply between two power supplies is up to 200M line now the situation is DC / DC power supply at no time when the load is measured at this time DC / DC power input It is actually less than 15V if the DC / DC power supply is loaded with about 10W and the 24V power supply output is adjusted to 27V or more when the DC / DC power supply is working In front of the wrong In the load when the 10W when the front power output is adjusted to 27V measured when the power input voltage is 14.5V or so when the no-load time is normal add another point With 10W when the front of the power output is adjusted to 27V below the two power between the current is significantly increased at this time into the DC / DC power supply voltage from 15V down to 6,7V looks more like the back of the power from Excited and DC / DC of this power supply in the 9V or so input conditions can work properly: There are three problems need to be identified, 1 is the power output power in front of how much, if small, can not be changed, only for the front of the power; 2 is 200 meters diameter, if too thin, a little current Will produce a lot of pressure drop, you can change the thick line? 3 is the power requirements of the back of the input voltage is how much, if the low limit close to 24V requires the front power supply has sufficient capacity, the transmission line pressure drop as small as possible.

Q: What is the flashing time in the switching power supply?: Blanking time intuitively speaking, in this period of time the controller does not move. For example, IC current detection pin, whenever the power MOSFET to open a current sense resistor is not inevitable to produce a peak voltage.

Q: Note the operating conditions of 220V voltage and the order of switching power supply: 220v are low-voltage circuit, there is no provision, as long as the attention of several points: 1, do not touch the live part directly. 2, if you want to live work, you must ensure that the human body and the earth insulation (standing on the bench or insulation pad). Can not touch FireWire and Neutral Line at the same time. 3, the normal operation of the order: to use the switch off the circuit, first pull the sub-gate and then pull the total gate, the first joint gate and then sub-gate. Line maintenance sequence: Power off - pull the security ground - proof signs pull off the line - operation - review the operation is correct to complete the task - remove the insurance ground - remove the warning card pull off the line - power

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: As shown below, I used a switch chip tny276pn, optocoupler pc817, regulator source tcl431 and some small components (capacitors, resistors, etc.) designed a 5Vdc switching power supply. Transformers are custom, according to the flyback type, 132kHz, 85 ~ 265Vac parameters to do. The upper right corner of the picture p2 end is a 20-30 ohm coil, and now found that the input voltage dropped to 20Vac, 5Vdc was unstable, coil control of the magnet was to jump, I would like to 20Vac this parameter increased to 60 ~ 80Vac, So that the coil control of the magnet in the low voltage when the high jump, how should modify the circuit? Thank you.: The maximum power of your power is 1.25W, the overall power supply power by 70% efficiency of 1.8W. In this case need to modify the transformer. To the place there are the following: 1, the transformer to increase the ratio; such as the original is 200: 5, now changed to 300: 5. Now want to do your request 60-80VAC input protection, you need the current transformer parameters to be calculated; 2, the transformer sensation increased; proposed to change to 4mH ~ 8mH. Once the two done, the protection voltage will rise.

Q: How the phase margin and gain margin of the switching power supply are measured: 2. Disconnect the loop at your feedback sampling point and access the signal output channels of the spectrum analyzer (all differential output signals, in order to inject a perturbation signal from the spectrometer to the circuit).

Q: What is the difference between a switching power supply and a switching regulator?: 2, switching regulator, the key word is in the regulator, so the output of the switching power supply has a negative feedback sampling circuit, can play the role of regulation, usually switching power supply efficiency will be relatively high, the input dynamic range comparison Large, dynamic response is better, so now more widely used.

Q: What is the output of this group? If the power supply to the 48V, is not +24 V termination of the electrical 48V + input, -24V termination of the electrical 0? is this okay? Voltage difference is 48V ah? Thank you very much!: When the positive ground, then the voltage is -24V, because the earth is zero potential surface

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.

Q: What is offline LED driver? Offline switching power supply: Offline LED driver is a circuit using EMI suppression circuit, rectifier filter circuit, paddle PFC circuit, AX2028 constant current system circuit to drive LED work, LED products to drive the power requirements include: stable, reliable, efficient, common. AX2028 is a constant current LED control chip, the system application voltage range of 12VDC to 600VDC, duty cycle of 0 to 100%, fixed off time mode of operation. It supports AC 85V ~ 265V input, non-isolated and isolated applications. AX2028 uses a unique technology for constant current control and compensation methods, the LED current in the exchange of 85V ~ 265V range of less than ± 3% .AX2028 using optimized system structure, making the system efficiency is higher than 92%. Can be widely used in E14, E27, PAR30, PAR38, GU10 and other lamp cups and LED fluorescent lamps.

We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
