Q: What is the difference between variable frequency power supply and regulated power supply? The The The Is there a variable frequency band? 220V single-phase power supply with 30KW it: Central South Central power supply is the production of variable frequency power Of the manufacturers, there are problems can call funding.

Q: What is the main domestic DC power supply brand? Need cost-effective? Quality assurance: the specific price you need to talk to their agents and their own. Hope to adopt.

Q: Will the adjustable power regulator what brand is good: If you need good quality, you can consider the following: ? Japan Kenwood / KENWOOD ? Japan Kikuchi / KIKUSUI ???????? Work and quality are good, but the price is also very high.

Q: DC power supply CH1.CH2 two channels with wire connection and not connected What is the difference: And then from the negative electrode of CH1 and the positive electrode of CH2 (presumably, the detailed need to look at the Intel Rotter IPD-3305SLU instructions) leads to a line connected to your load on the line. Do not need to do their own in the output and in series connection operation.

Q: Can DC power supply be used as a charger for lithium batteries?: Can not be directly as a lithium battery charger. Lithium-ion battery on the charger requirements are higher, in the initial charge should be in accordance with the constant current charging mode, theoretically the smaller the charging current the better the battery, but it takes too long is not practical, China's national standard low-rate charge Is 0.2C (C is battery capacity). Battery voltage with the charging process gradually increased, when the battery voltage reaches 4.2V, you need to change the constant current charge for constant voltage charging. With the constant charge charging process continues to reduce the charging current gradually, when reduced to 0.01C, that charge termination. As the lithium-ion battery nominal voltage of 3.7V, charge cut-off voltage of 4.2V, there are significant differences, so the use of fixed voltage regulator power supply can not be constant current charging, must start the current is too large, or the back of the current is too small. If the voltage regulator of the voltage regulator is low, although the starting current is not large, but there will be full of dissatisfaction; if the tune is higher, the initial stage of charge due to the battery voltage is too low, the pressure difference is too large Charging current Excessive shortcomings, greatly shorten the battery life; if the output voltage accuracy is poor, the voltage exceeds the upper limit of 4.2V, will occur overcharge, serious damage to the battery. In addition, the regular charger is also equipped with: the temperature control during charging; LED charging status indication; battery abnormal state detection and other additional circuit functions. So the DC power supply must be through a dedicated constant voltage, constant current control circuit to charge the lithium battery.

Q: Members help me to explain the role of the various components in detail. The There D5 regulator is 21V why the output is 20V, they said to reduce the UBE0.7V pressure drop. I do not understand, why should subtract UBE ah? The more detailed the higher probability of adoption. The Remember the details. The The Thank you all the teachers. The ? Mainly three-tier tube is how to complete the regulator?: You are right, the current is so gone. Regulator tube can indeed be seen as a voltage source, but the internal impedance is very large. By reason, with the regulator can also be directly for the power supply, but then, the resistance is the current limiting resistor, the output current will be small, may not meet your requirements. With the transistor as a regulator tube, a big reason is to reduce the power supply resistance, increase the power output capacity (current).

Q: DC power supply correct use of the method?: The third step, set the output voltage. By adjusting the voltage setting knob, the digital voltmeter shows the target voltage, complete the voltage setting. For adjustable current limiting power supply, there are two sets of adjustment system to adjust the voltage and current. Adjustment to be clear, the general adjustment of the voltage potentiometer "VOLTAGE" words, adjust the current potentiometer "CURRENT" words. Many of the entry-level products use low-cost coarse / fine twist knob settings, encounter double adjustment knob, we first fine knob knob to the middle position, and then through the coarse knob to set the approximate voltage, and then fine knob Precise correction. Step 4, set the current. Press the "Power" button on the power panel, then the ammeter will show the current value, adjust the current knob, so that the current value reaches a predetermined level. The general current limit can be set at 120% of the maximum current used. Some power supply without limiting the special adjustment button, the user needs to follow the instructions required short-circuit output, and then according to the short-circuit current limit with the current limit set current limit. Simple adjustable power supply without current setting function, there is no corresponding knob.

Q: Maintenance of mobile phone power supply is best used to what: The use of transformer power supply, ripple is relatively small, ripple small noise, because the communication equipment, high noise requirements.

Q: How the DC regulated power supply outputs a negative voltage: 3, the power supply of the classification of many methods, according to the type of output power supply DC power supply and AC power supply; according to the regulator circuit and the load connection is divided into series power supply and parallel power supply; The working status of the tube is divided into linear power supply and switching power supply. According to the circuit type, there are simple power supply and feedback type power supply. So many of the classification is often so that beginners puzzled, do not know where to start. In fact, it should be said that these seemingly a lot of classification between the methods have a certain level of relationship, as long as the level of this level can naturally distinguish the type of power.

Q: DC adjustable power supply DC adjustable power supply manufacturers which is good?: Honghai Electric to the results as a new starting line, adhere to independent innovation, scientific development, take the market, brand, technology, production, personnel, management, capital internationalization of the road, and strive to build a red sea electrical power into a strong competitive enterprises.
