The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available FR-A840-04320-2-60.
Please select according too the required braking torque. "MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 400KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-A840-04320-2-60 FR-A840-04320-2-60.
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way MITSUBISHI FR-A840-04320-2-60.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic MITSUBISHI FR-A840-04320-2-60.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions MITSUBISHI FR-A840-04320-2-60.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly used in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter. "
MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 160kw.
SLD converter rated current: 432A.
Structure and function: Standard model.

Mirror like ultra fine processing.
In order to adapt to the new material diversification, the machine adopts the most cutting-edge technology, more than ever more slim hard.
In order to be able to realize the fine cutting, grinding on the hard and hard material,
The need for high-speed operation has become more and more strong.
In order to cope with the increasing demand of logistics, every port in the world has a crane in every day FR-A840-04320-2-60.
A container filled with cargo.
We can achieve a new type of inverter products under the conditions of low speed and high torque to achieve smooth cargo handling operations,
Carry on the smooth movement to the heavy.
