Key Features and Advantages
The high reliability of our VFD systems is achieved by multifold innovations including patented technologies of serial communication, pre-charging, automatic recovery, vertical ventilation & heat dispersion, and so on.
Patented communication technology
The communication between the control system and the power cells is in serial. Compared to parallel communication, the reliability of communication can be improved four times with this innovation.
Patented pre-charge technology
The pre-charging function can effectively control the charging speed of the capacitors, and thus charging shock can be prevented. Together with IGBT intelligent driving technology, the innovations can double the lifetime of the capacitors, from 5 years to 10 years for instance. The maintenance cost can be lowered significantly.
Patented automatic recovery technology
With real-time monitoring, the VFD system can identify the causes of power cell bypass, and automatically restarts once it detects the problems are fixed. It ensures equipment to operate continuously and stably when the bus power supply has instantaneous failure.
Patentedventilation and heat dispersion method
Our VFD’s ventilation system is centralized and vertical. It has significant advantage over the distribution type in terms of temperature field control, air flow distribution, and wind speed uniformity. Since the capacitor units are located at the ventilation ducts, it is estimated that the lifetime of capacitor can be doubled, and thus the overall system service time is prolonged with this cooling mechanism.

- Q:Can the laptop power adapter be generic?
- Not necessarily, the laptop power adapter has two interfaces for input and output. 1. Input interface is connected to the power outlet, generally divided into two holes and three holes, as well as round mouth and flat mouth of the points; 2. Output interface is connected to the computer side, size, length, diameter, diameter, the pin may have differences, common are: diameter 2.5MM, ordinary mouth, mainstream interface; OD 1.7MM, small mouth; MM, big mouth with a needle, round mouth with a needle and so on. 3. Different voltage, different brands of laptop power adapter voltage is not the same 4. Current is different, different brands of notebook computer power adapter current is not the same In summary, the laptop power adapter between the different types, basically not common
- Q:Variable frequency conversion frequency difference characteristics based on,
- Pole is the pole pair. So that the synchronous speed has changed, you can speed, but can not smooth speed.
- Q:Laptop power adapter is used to do what
- The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
- Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
- If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
- Q:Is the laptop power adapter AC and DC?
- Notebook power adapter is not AC and DC. Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformers and rectifier circuit, the working power for the exchange (China AC standard AC 220V), according to its output Types can be divided into AC (AC) output type and DC (DC) output type. General notebook power adapter are DC output, is the exchange of DC conversion equipment.
- Q:4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
- About 2,000 yuan, electromagnetic speed and vector inverter can bring feedback
- Q:380V 2 pole motor can use the inverter?
- Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
- 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:Laptop power adapter repair how much money
- Look at your warranty period had no, no contact the seller can be free for a new one. If there is no need to repair the warranty period. Now the maintenance point is too lazy to repair. Suggest you follow your computer brand with a new one Because the maintenance fee to buy a difference can not be much money and the quality is not guaranteed, a power adapter is now dozens of dollars
- Q:Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
