Q: 3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A: Probably the error of the clamp meter. 4 more current is correct.

Q: Laptop power adapter repair how much money: Dell laptop warranty 36 months of hardware include: CPU, memory. Warranty 24 months of hardware include: motherboard, graphics card, LCD screen, hard drive, power adapter, keyboard, mouse module. Warranty 12 months of hardware include: LCD accessories, CD-ROM, DVD, CDR / W, floppy drive, Modem card, network card, camera and other functional modules and components. Battery warranty for 3 months. Random disc, random gift of micro-computer products such as warranty 3 months. The

Q: Laptop power adapter bad what is the phenomenon?: If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,

Q: Variable frequency pump pressure in the very low flow instability, why?: . If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.

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: What are the AC motor speed control methods? What are the characteristics of each: 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency

Q: How to learn the inverter debugging and design parameters: You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.

Q: The laptop's power adapter can be used on a desktop computer: First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.

Q: Why G120 inverter to be equipped with 4-pole motor?: On the upstairs that the motor parameters to be set on the possible, such as voltage, current, power, power factor, rated efficiency, rated frequency, rated speed, motor overload factor

Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together: Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
