Product Description:

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:Laptop power adapter aging
This should be no, play the game automatically shut down should be detected other
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
Second, the use of low-speed inverter motor. Ordinary motor running for a long time, heat is certainly not work.
Q:What is the output voltage of the laptop power adapter?
16V to 20V, different brands may be different, 19V, 20V more.
Q:What are the types of power adapter used in notebooks?
With the increasing popularity of notebook computers, the power requirements have increased. In addition, because the battery capacity (or density) increased, charging requirements also increased - so the laptop computer power requirements have doubled. However, larger and / or hoter power adapters are not an attractive option for millions of users who carry laptops around the world. Attractive is to have a compact, but instantly charged laptop adapter. Of course, it will not produce heat, and will not cost too much. In recent years, the development of electronic products has not increased the hope in this regard, and whether the future revolution can be achieved is still a pending issue. We also want to use a laptop adapter that can be used globally without the need for a 110/220 volt operating voltage selector switch - so the laptop adapter must be designed for truly universal line voltage operation. At the same time, regulators and OEM expectations also play a role.
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
Q:Can the notebook's power adapter be mixed?
At present, the market sales of notebook power is generally 90 watts and 65 watts two, using integrated graphics, or configure the low-end notebook, usually 65 watts. Using the independence was, the configuration of high-end, or the game audio and video of this, are generally 90 watts. If the laptop's power adapter is damaged can not be used, it is best to repair the department as soon as possible to repair. If it is for emergency, before using the two adapters to check the output power and current and voltage are conceded, as the adapter input current and voltage is not the same, should be the general household voltage is 220V, so almost all of the notebook power The adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and wattage equal, and then one is the same interface, you can mix. In general, the voltage is stable, the output wattage is the same, the notebook is basically no harm.
Q:The notebook power adapter flashes
The problem is very simple Well, used to know all the notebook Kazakhstan, the adapter has a light above, if it is lit that is the problem of the notebook, the other side of the notebook above also have a power indicator, the notebook above prompted the red, but not Rushed, that is, the problem of the notebook, the computer problem, you directly on the factory is finished, if the insurance, and casually find a place to repair a Kazakhstan, 50-80 yuan if the adapter is bad, buy a generic You can, but also more than 50 points, the last time I bought a bad 58 yuan, ASUS GM, to help people in the end, to give you a shop to buy the adapter, you ask the owner of Kazakhstan to get,
Q:Laptop power adapter leakage
Not a leakage of electricity, switching power supply design is the need for anti-interference caused by the leakage current, a lot of adapters have this phenomenon, but no harm to the human body is safe, you do not have to buy to replace, the original is good. If you have a protective ground at home, then you can not feel the leakage, because the leakage current from the protection of the ground to the earth, and really leak, then your home leakage protector on the trip.
Q:Is the laptop power adapter hot?
Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured.
Q:Laptop power adapter how to detect?
No load voltage, DELL plug more special, the middle needle no load measurement is no voltage, the outer ring outer house and the wall only 19.5V voltage
