MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740P-75K-CHT
"MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 75KW.
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.
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.
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.
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. "
Power: 15kw.
Voltage: 200V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost MITSUBISHI FR-F740P-75K-CHT.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving FR-F740P-75K-CHT For the operation panel (FR-DU08) between the connector and the connecting cable.MITSUBISHI inverter series: FR-F842.
Voltage level: three phase 400V.
Power: 355kw.
SLD converter rated current: 770A.
Structure and function: the rectification part is off type MITSUBISHI FR-F740P-75K-CHT.

Energy saving by high efficiency motor.
Reduce standby power consumption.
DC24V external power supply, the input MC signal can be stopped after the motor for the OFF, in the motor drive for the ON.
Standby power management can be carried out by means of frequency converter to realize the power consumption reduction of standby time.
According to the temperature of the inverter cooling fan, the operation of the inverter can be controlled MITSUBISHI FR-F740P-75K-CHT.
According to the operating conditions of the inverter cooling fan output the corresponding signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation.
Can reduce the power consumption in the stop. Superior high efficiency IPM motor.

IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM mmotors at the same time FR-F740P-75K-CHT. Power: 75kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connectedd without built-in brake transistor inverter FR-F740P-75K-CHT.
Three types of discharge resistors are available.
Please select according to the required braking torque.
