Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
The general MV VFD has the following protection functions and features:
Overload and over-current
Phase loss and grounding
Over voltage
Overheat
Current limit
Redundant control power supply
Cell Bypass (optional)
Cabinet door alarm
Phase-Lock function
Synchronous Switching between VFD and Grid system
Soft start of motor
High efficiency >98% (VFD at full-load)
Electrical Isolation by the optic fiber
Built-in PID regulator
RS485 communication with the protocol, Modbus as standard, optional Profibus-DP, Ethernet,etc
Accurate fault records, easy to check fault history
Compact structure and layout, customized design is available
- Q: What is the application of variable frequency speed control?
- Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
- Q: Pump frequency converter instantaneous restart and restart the problem
- Speed tracking start. The specific to ask you to drive the inverter that guy. He earned your money there is a need for technical support
- Q: What is the working principle of high voltage electrodes and frequency converters?
- High-voltage inverter is the input power supply voltage above 3KV high-power inverter, the main voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and other voltage levels of high-voltage high-power inverter High voltage inverter from high - low - high; low - high; high - high points.
- 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: Is the laptop power adapter long-haul?
- This is not good, If you need to shut down, then it is recommended that the power adapter plug from the board to pull down. Because if only pull the adapter and the computer plug so that the adapter will still have the internal current through, hear the small sound is actually the sound of the current. So it is recommended that the power adapter from the outlet on the unplugged, and the computer connected to the one do not have to pull, so that will not cause the power adapter power and convenient computer to open.
- Q: Do you want to pay attention to the number of poles of the motor when selecting the inverter?
- Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.
- Q: My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
- Q: Which machines are used for the frequency converter
- Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply, air conditioning and other fields.
- Q: I power adapter output current 3.25A for a 4.5A, can you use it
- No problem that nominal value is that the adapter can provide the maximum operating current to your computer current is not so big
- Q: Computer frequency changer to do cd frequency changer how points positive and negative
- . In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.
