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

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:Jd1a-40 motor speed controller and how to connect the motor
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor circuit in the adjustable additional potential to change the motor slip, to achieve the goal of speed. Most of the slip power is absorbed by the additional potential in series, and then an additional installation occurs, and the absorbed slip power is returned to the grid or converted to the energy. According to the slip power absorption application method, the cascade speed regulation can be divided into the motor cascade speed regulation, the mechanical cascade speed regulation and the thyristor cascade speed regulation situation, take the thyristor cascade speed regulation, Suitable for fans, pumps and rolling mills, mine hoists, extruders on the use. Fourth, winding motor rotor series resistance speed control method Fifth, the electromagnetic speed control motor speed method Six, hydraulic coupler speed control method This method is suitable for fan, pump speed.
- Q:The laptop's power adapter is broken how much it costs
- Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
- Q:Is the laptop power adapter high temperature normal? Is there anything else?
- Hello, the power adapter because there are a lot of electronic components so hot is normal, the general hand feels hot does not feel hot on it, if hot, then there is a problem.
- Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
- Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
- Q:Laptop power adapter problem
- First, that is called the transformer, not called the charger, not with you bite the word, but you according to the charger to Taobao search, basically one hundred percent are not found.
- Q:Laptop power adapter repair how much money
- Dell laptop warranty 36 months of hardware include: CPU, memory. Warranty 24 months of hardware include: motherboard, graphics card, LCD screen, hard drive, power adapter, keyboard, mouse module. Warranty 12 months of hardware include: LCD accessories, CD-ROM, DVD, CDR / W, floppy drive, Modem card, network card, camera and other functional modules and components. Battery warranty for 3 months. Random disc, random gift of micro-computer products such as warranty 3 months. The
- Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
- Change 6 will only be slower, the fan is no longer role. The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.
- Q:What is the working principle of high voltage electrodes and frequency converters?
- The general high and low methods are used in low-power high-voltage motor to do with energy-saving energy. Low-high-mode high-voltage inverter is controlled by a low-voltage inverter, the voltage directly to the motor with a step-up transformer voltage. Low-high mode is also used in low-power high-voltage motor to do with energy-saving energy.
- Q:What is the principle and implementation of the inverter?
- How the inverter works: 1. DC can be converted into alternating current through the oscillation circuit 2. The resulting AC power is then boosted by the coil (in this case, the alternating current of the square wave) 3. Rectify the resulting alternating current to obtain a sine wave
- Q:What is the common COM point of the PLC and the inverter? Is it positive?
- It depends on your PLC and inverter I / O is what type, the most simple can be divided into two kinds of NPN and PNP, NPN COM point is negative, PNP COM is positive.
