FAQ

What is the frequency converter used to do, why some motor with the inverter?

Speed control, there are speed requirements of the place are in the inverter

Do you need to rectify before switching?

Need to rectify. The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.

Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?

The existing Taian inverter 380V3.7KW can bring 4.0KW 2 pole motor, 18000 to 300HZ can also see how you load, It is best to check your wiring tightness and whether the load is stuck. It is recommended to use the N310-4005-S3 this model, such as with the E510-405-H3 better.

ASUS notebook power adapter can be universal? is it?

ASUS notebook power adapter is not universal, depending on the model, the output voltage and current requirements are different, select the battery and consistent adapter. Note: different brands of laptop batteries may be different, so do not use, through the laptop battery voltage and current comparison power adapter voltage and current to judge. If the voltage and current are roughly the same can be used.

The Schneider inverter reports the nlp command

Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered

Do not the laptop directly connected to the power adapter?

2, due to the different configuration of the notebook, its power consumption also has a variety of specifications. Common for more than 60W, the configuration of some of the 90W, and the game adapter power in more than 120W, such as dual GTX1080 card crossfire Blue Star prototype, power consumption in more than 400W, the use of two 320W power adapter for its power supply;

Is the laptop power adapter high temperature normal? Is there anything else?

Summer heat is normal, as long as it is not the kind of hand touch on the bubble temperature, no problem

Three motors, if coupled with the governor speed, is it necessary to add the inverter?

?Second, the variable speed: change the way the stator winding wiring to change the cage motor stator pole pairs to speed.
