MITSUBISHI FR-F740-3.7K-CHT Product information and technical parameters:
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740-3.7K-CHT
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 3.7KW.
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 device is the first 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. "

"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
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 device is the first power of the AC power conversion to DC (DC), the process is called rectification FR-F740-3.7K-CHT.

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. "MITSUBISHI inverter FR-D720 series FR-F740-3.7K-CHT.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-F740-3.7K-CHT. Power: 2.2kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in tthe FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-F740-3.7K-CHT.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr power used to select the DC reactor FR-F740-3.7K-CHT.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
