Q: How to check the switching power supply leakage current: 60601 or 60950, third line class I or two line class II, but no matter how! General market has a special test switching power leakage current tester, you can check the Internet, because I have used before But the manufacturer model forgot.

Q: 24V switching power supply, 220V input and output three terminals: 24V + 24V- GND. Excuse me. Where is this GND connected? In the PLC (such as Siemens) on the L + M to (ground that symbol) Switching power supply is connected to the ground in the PLC? There are some sensors on the terminal marked with three vertical and horizontal grounding symbol, but also to be connected to the switching power supply on the symbol terminal? What is the relationship between the chassis and the switching power supply on this land? Is it a thing?: 24V switching power supply, 220V input and output three terminals: 24V + 24V- GND. Excuse me. Where is this GND connected? " The switching power supply is a dual power supply that is positive or negative output, but we commonly used electrical equipment is generally used in the positive end 24 + then negative on the receiving GND. If your electrical equipment then +24 and -24 port, then 48V will burn. In a word, it is estimated that your electrical equipment is a positive power input, you can then +24 and GND "What is the relationship between the chassis and the switch on this ground? Is it a thing?" They are not the same. Case is the anti-touch the earth. The power source is quite zero with the point. The other has not seen in the end what, do not know I do not say On the first floor is the input of the land

Q: 12V7A motorcycle battery can not use 14V3A switching power supply charge: Can be used, but can not often use, because: 12V7A battery suitable for the charging current of 0.7-2.1A, 3A current slightly larger. But if you insist on the use of a small change, do not change the original switching power supply, only need a series resistance, resistance size of about 1 ohm, power of 5 wirewound resistors, so that the output current can be controlled within 2.1A, You can also ensure that the battery can be fully charged.

Q: We use the switching power supply is 220v-48v, the room has air conditioning, air conditioning power in 6kw or so, the total power of this room in 17kw, DC current is 60A, the room has two tubes. Now do not know how much switching power supply losses, these devices may have 17kw power? This is the 17kw power meter on the show. Who heroes help me.: Are you going to calculate the actual power consumption of the switching power supply? This requires knowing the load current or load power of the switching power supply and the efficiency of the switching power supply. General switching power supply efficiency (220v-48v) is greater than 80%, 80% efficiency, its power consumption is equal to the load / 80%.

Q: 24-volt switching power supply why leakage: 3, the real induction power, as long as the power supply, whether it is power or switching power supply, the general transformer high voltage low side will have an equivalent capacitor, can be seen as the first two conditions, there will be a trace of leakage current, This situation can not be avoided.

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.: How do not provide transformer parameters? 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. I am an electronic design engineer, is developing a 12V20A repair charger, you can add to my discussion.

Q: Switching power supply how to connect to the battery charge: The output of the switching power supply is connected to the positive pole of the battery, the output negative of the switching power supply is connected with the negative pole of the battery, and then the switching power input terminal can be inserted into the socket. If you do not know the battery and switching power supply positive and negative, you can use a multimeter to connect the switching power supply output port test, the display voltage is positive, then the red pen is connected to the positive, black pen is connected to the negative.

Q: I am in Guangzhou, need to purchase switching power supply, would like to know how we look for channels to buy? A lot of come to recommend the manufacturers, there are many outside the electronic market, there are a lot of online, I do not know how to distinguish between good and bad ah .... how to cost higher?: Shenzhen Luyuan Rui Di Electronic Technology Co., Ltd. is a professional design, development, production and sales of switching power supply professional company, the product has a low price, high reliability, high efficiency, low operating temperature Small size, light weight, etc., widely used in industrial control preparation, LED display, instrumentation and other industries, is the traditional control transformer ideal replacement products.

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: Find the correct use of this constant voltage constant current switching power supply, and the current adjustment method: Constant current switching power supply load regulation should be the same as the output current, the load (constant current type power supply is allowed to short circuit, short circuit output current should be its rated current) from the short circuit to the output voltage to the rated value , The percentage change in the output current. Usually the short circuit in the case of current will be too large, when the voltage close to the rated current when the current will be small. Only on behalf of personal views.
