Laptop adapter heat
Many friends to buy a laptop or laptop power, you may encounter the power did not take long to heat on the hot, and even hot to dare not get the situation, in the end is the quality of power problems or how is it? With the ever-changing notebook frequency, notebook power adapter power is also sesame flowering high, even to 100W or so, almost a small desktop power! Touch the hand, timid may be scared, obediently, is simply a hot potato! What will not fire? This is a lot of people worry! Compaq, IBM, such a large company to recover several back to the power adapter, it is because of fear that there may be defects due to power supply design, and will cause a fire!
Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Note that the quality of the inverter is not ye, and now this situation is already very rare, it is recommended to replace the inverter brand, you can use Bosch Rexroth, the British Witten, Huichuan, Senlan, Haili Pu, Ou Rui, etc. Branded.
On the notebook power adapter output current and voltage issues
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
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.

Is it right? The next manual to see do not understand
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.
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.
