Power: 37kw.
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 the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor FR-F740-S160K-CHT datasheet PDF catalog FR-F740-S160K-CHT PDF datasheet FR-F740-S160K-CHT (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Total points: 40 points.
Input points: 24 points.
Output points: 16 points.
Voltage: AC220V.
Output type: relay.
Outline dimension: 130*75*90 FR-F740-S160K-CHT datasheet PDF catalog FR-F740-S160K-CHT PDF datasheet.
FX1N series is a very powerful micro PLC,
Can be extended to up to 128 I/O points,
And can increase the special function module or the expansion board.
Communication and data link function options make FX1N in the volume, communication and special function modules and other important applications is very perfect. Can be used as a screw relay terminal. Positive common end use."MITSUBISHI inverter FR-F720P series FR-F740-S160K-CHT datasheet PDF catalog FR-F740-S160K-CHT PDF datasheet.
Voltage level: three phase 200V.
Frequency converter capacity: 7.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
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 aand meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FR-F740-S160K-CHT datasheet PDF catalog FR-F740-S160K-CHT PDF datasheet.
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 FR-F740-S160K-CHT datasheet PDF catalog FR-F740-S160K-CHT PDF datasheet. "
