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:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some
Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
If the machine needs the same speed, constant 500r / min This can be directly with the motor, remove the inverter, but also save costs, while the motor at 50Hz, the maximum power point of rated power. Output torque is the most stable point. The pulley diameter becomes smaller and the reduction ratio increases, and the torque required by the motor becomes smaller, which is advantageous for the motor. 960/500 = 1.92, that is to say the motor pulley compared to the original tune less 1.92 times
Q:Laptop power adapter how to detect?
No voltage output when no load.
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:How to learn the inverter debugging and design parameters
You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
Q:In the official website to buy ThinkPad notebook, to the power adapter?
Hello, generally there will be a power adapter with Kazakhstan, unless there is a special note bare metal
Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
May be mechanical part of the card, try idling motor.
Q:Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
Sure answer, no! Rest assured with it, but be careful not to buy the cottage goods, this on the computer and security is not good. good luck!
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
First, the frequency control: the use of frequency converter to change the frequency of the motor stator power supply, thus changing its synchronous speed control method for all motors, which is the most advanced, the most widely used speed control method.
