Q: What are the types of power adapter used in notebooks?: Notebook function is limited, such as power requirements of only 50-70 watts (W). In recent years, power requirements have risen above 100 W, but the expectations for weight and size have not improved accordingly. In addition, the need to meet the low standby power performance in the specification, external power (EPS) efficiency requirements and IEC1000-3-2 harmonic power requirements above 75 W make this challenge more difficult to deal with. This article explores new trends that enable power supply manufacturers to address these challenges and provide alternative solutions to choose from.

Q: How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?: Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next

Q: If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?: If the control accuracy is not high, then you can use the ordinary control. Since the choice of the inverter, it is best based on the motor nameplate to set parameters to ensure the stability of the motor running

Q: I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,: Second, the use of low-speed inverter motor. Ordinary motor running for a long time, heat is certainly not work.

Q: How to choose the inverter: and you need to know how The use of frequency converter, as well as voltage 380, are fixed, and the frequency can be changed

Q: There is no inverter comes with simple PLC programming function: Inverters are generally digital input, and analog input, a digital output, etc., can also be controlled by means of communication. Digital input can be used as a positive and negative and reset the alarm, the analog input can be given as a speed, and how to use the inverter to see the specific model. Take the Siemens inverter, MicroMaster420,567 terminal 3 digital input, 8 for the 24V, 9 for the 0V, you can usually open the point on the 8th 24V back to 567, as a digital input, you can also directly into the switching power supply Of the 24V, but the switch power supply 0V and 9 terminals connected to the potential, or the inverter may not be able to identify the outside world 24V. (DP communication, USS communication, etc.), with the terminal input on the P0700 = 1, the user can set the command source, the panel can be input, 2, P0701 to P0703 corresponding to the three digital functions: parameters set to 1 forward, 2 for the reverse ... ... a lot of features and control methods, see the corresponding product manual like

Q: Can the inverter be used to control the speed of the DC motor?: The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.

Q: What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor: 2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.

Q: Will the laptop's power adapter is not the original good?: Theoretically can be inserted into the use and will not have any obvious damage to the machine But it is best to buy the number of volt and your original consistent Original also has original benefits According to some "professional" sources claim that no original touchpad will have a slight jitter, I was not found

Q: Three sets of batteries (540V) DC power supply U / f inverter.: It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
