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 different brands of laptop power adapters be generic?
- 1, strictly speaking, different brands of laptop power adapter is not common. Even if the logo on the voltage and current are the same should not be mixed, will cause the power interface or motherboard failure or even damage. 2, with the same brand of different models of the power can be used temporarily, but should not be used for too long. 3, the cottage power adapter is best not to buy the use of hidden dangers, including spontaneous combustion and explosion, try to use the original power adapter.
- Q: What is the difference between variable frequency motor and variable speed motor?
- The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
- Q: Pump frequency converter instantaneous restart and restart the problem
- Inverter speed: Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values ??every 25μs. The torque comparator and flux comparator compare the actual values ??of torque and flux with the reference values ??for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.
- Q: Can the laptop 1.3a power adapter be used on a 1.5a device?
- No, use a power adapter that is equal to or slightly larger than 1.5a.
- Q: Do you need to rectify before switching?
- I used to do the frequency of the words to be rectified
- Q: Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
- Inverter general control object is the AC motor, you are the AC motor, then the general inverter will be able to achieve start and stop, select a reasonable power section, a reasonable set of start and stop time can be very good drop protection motor. Can also achieve speed control function.
- Q: Does the inverter set the number of poles to match the number of poles of the motor?
- The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
- Q: Will the laptop's power adapter is not the original good?
- Theoretically can be inserted into the use and will not have any obvious damage to the machine But it is best to buy the number of volt and your original consistent Original also has original benefits According to some "professional" sources claim that no original touchpad will have a slight jitter, I was not found
- Q: B2b frequency how to speed
- AC motor speed control methods are four: frequency, transformer, variable pole and winding motor to change the rotor loop resistance of the speed control method. Its source is based on the motor speed formula: n = (1-s) * 60f / p where: n --- motor speed s --- motor slip f --- power frequency p --- motor pole Logarithm
- Q: First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
