- Q:65w adapter and 90w laptop power adapter What is the difference?
- In general, notebooks have to use power consumption is to decide whether to use 65W or 90W adapter power supply, but not to say that 90W must not use the 65W power supply, but his power is not reached, it is possible that the machine is using some of the features Can not start, for example, external equipment, power supply, if the original request is 90W power supply, but you are using the 65W power supply, external equipment can not work properly. But some cases do not need external equipment, so choose a small 65W power supply is very convenient
- Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- So that mainly depends on your application and the frequency of work in the number.
- Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
- Q:How to choose the right inverter?
- 1, constant power load
During the operation of the load device, the power remains constant. Such as machine tools, cutting machines, paper machines and so on.
For example: a marble cutting machine frequency conversion system, is a constant power load, load inertia, inverter selection configuration A power with the G-type machine, plus the braking unit and braking resistor.
- Q:ASUS and dell notebook power adapter can be universal?
- One, not necessarily interchangeable. Need to compare the two adapter specifications to determine:
1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute.
2, however, some foreign imports of products using 110V AC products, be careful to see clearly.
3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter;
Second, for example:
1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W;
2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
- Q:My Lenovo v450 laptop power adapter should be bad how to match?
- In order to ensure quality, we recommend that you buy genuine, you can contact the service station to buy engineers
- Q:Laptop power adapter problem
- Second, the transformer This thing is not standardized production, the result is that even if the parameters of the same, the transformer to get another of this may not be compatible with the use of the explosion with the use of the cup like the situation, so we generally Stressed the original transformer.
- Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.
- Q:Variable frequency pump pressure in the very low flow instability, why?
- From the performance curve, the flow becomes smaller, the combination of pressure and frequency adjustment flow will only stabilize the flow at a small value, the pressure will be reduced, because the work point will move down.
- Q:Can the inverter stop intermittently during operation? If so, how to connect and set up
- Look at your inverter manual, because the inverter is not a simple wiring can run, first of all have to know that a few are external terminals (inverter input terminals),
