General Introduction


From the above, different voltage output, the quantity of power units is different, but the working theory is exactly identical. All power units receive the indicator from same central process controller. There is a phase difference in secondary windings of transformer which provide energy for power unit, in this way, most of the harmonics current caused by independent power unit will be eliminated, so the primary winding current is approximately sine wave, the harmonics current flowing into power grid are so few, even under the rated load, the harmonics contents is lower of 3%.

 

The power unit is AC-DC-AC structure, equivalent to a low-voltage power source inverter of 3-phase input single-phase output. The rectifier side is diode three-phase full bridge circuit and the IGBT inverter bridge can be controlled through sine PWM mode to output single-phase AC. All power units are fully identical in structure and electrical performance, very easy for maintenance and replacement.


Energy Saving Fields

  • Power Generation: Induced draft fan, forced draft fan, condensate pump, feed pump, primary air fan, secondary air fan, booster fan, circulating pump, mill fan, slurry pump etc

  • Cement: draft fan, high-temperature fan, air blower, dust collection fan, grinding machine etc.

  • Metallurgy: blast furnace blower, slurry pump, feed water pump, dust fan, compressor etc.

  • Petroleum&Chemical: Water injection pump, crude oil pump, Compressor, fan, circulation pump, etc

  • Urban water supply: Water delivery pump, water intake pump, water supply pump, sewage treatment industry, self-fractionating pump etc

  • Minerals & Mining: Mud pump, ventilation fan, belt conveyor, slurry pump etc
    Others: Loads such as fan, pump and compressor in pharmaceutical, paper making and wind tunnel test.

     

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.

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:The laptop's power adapter is too hot to do
Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Which model ah, CE alarm, it should be communication failure. CE4, it seems that should be written to the read-only address. You follow the inverter model, to the Delta website to download the corresponding manual, there are fault alarm instructions.
Q:How does the laptop's power adapter open
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:Can the HP laptop's power adapter be universal?
Power supply low-voltage plug to the same, the voltage to the same, the current is greater than or equal to can be used
Q:22kw.2 pole fan can use Fuji inverter?
according to the rated name of the fan brand and the inverter rated current control, select the current value match, or slightly larger The
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
Q:Jd1a-40 motor speed controller and how to connect the motor
First, variable pole alignment speed method This method of speed control is to change the stator winding winding red method to change the cage motor stator pole pairs to reach the speed control target, the characteristics are as follows: This method is suitable for production machinery which does not need stepless speed regulation, such as metal cutting machine, lift, lifting equipment, fan, water pump and so on. Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing the speed of its synchronous speed control method. Frequency converter system can be divided into exchange - DC - exchange converter and exchange - exchange inverter two categories, most of the current domestic use of cross - straight - cross frequency converter. Its characteristics: This method is suitable for the requirements of high precision, better speed performance.
Q:What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
Analog signal input: Reference setting Input voltage Positive terminal (0 --- 10V)
Q:ASUS notebook power adapter can be universal? is it?
Dear ASUS users, you may wish to refer to the following information: 1, you can use the same power ASUS adapter, is common; 2, the adapter recommended to the service center to buy original adapter, you can ensure the stability of power supply, the machine is not damaged;
