Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.: If the frequency converter is selected according to the motor rated current, then the motor current exceeds the rated current, the inverter will become overcurrent protection In this case, that is, when the inverter began to select the amount of time to stay the lack of the same power, inverter general type than the fan pump type current capacity of a high grade If the inverter selection is no problem, then please see whether the inverter is working temperature is too high, too high will cause the electronic components to resist the decline in current. First, check the inverter to work the ambient temperature, the second Please check the inverter fan is damaged, clean down the inverter fan channel and fan to see if there is no plug

Q:The laptop's power adapter is broken how much it costs: Hello, this is not very expensive Generally in 80 or so, you can go to the Internet to see the model, and then to the store to buy the price on it.

Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?: Inverter selection is mainly to see the power, and then pay attention to voltage problems. Finally look at what your motor is carrying.

Q:Can the inverter stop intermittently during operation? If so, how to connect and set up: One of these terminals is a common terminal, which leads from the common terminal and is connected to the corresponding terminal via the relay contact

Q:Is the motor having a variable frequency motor and a variable voltage motor?: Motor with DC and AC motor, variable frequency motor and fixed frequency motor, string motor, that is, I have not heard of a transformer motor.

Q:380V motor addition to the inverter, but also how to change its speed?: Rotary motor rotor series resistance adjustable speed. 4. Change the slip electromagnetic speed (slip motor)

Q:Laptop power adapter output voltage is not the same as the current? What's the effect?: so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply

Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!: And the inverter is connected to the positive and negative bk-dk electrical Han Han device,

Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?: If you use the environment is relatively poor, it is recommended that you use Austrian St. sealed inverter, this inverter can be moisture, dust, water, oil, corrosion.

Q:Lenovo g450 laptop power adapter specifications is what?: Lenovo g450 laptop power adapter specifications is what? Wrqwgp520 | viewed 4426 times Recommended at 2016-05-26 08:52:41 Best answer Lenovo Lenovo 19V4.74A G450 G470 Laptop AC Adapter: 【Power supply technical parameters】 1.
