FR-F740P-15K-CHT Single phase 200V inverter MITSUBISHI FR-F740P-15K-CHT It is based on the overall effect of three-phase waveform generation, 
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740P-15K-CHT
"MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 15KW.
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. "

MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.75KW.
Inverter output for the PWM wave, containing more harmonic.
Frequency conversion power sensor through the input voltage and current signals to exchange sampling,
Sampling value through cable, optical fiber and other transmission systems and digital input frequency conversion power analyzer,
The sampling value of the voltage and current is calculated by the digital input frequency conversion power analyzer,
It can obtain the parameters such as voltage effective value, current effective value, fundamental wave voltage, fundamental current, harmonic voltage, harmonic current, active power, fundamental wave power and harmonic power MITSUBISHI FR-F740P-15K-CHT MITSUBISHI FR-F740P-15K-CHT FR-F740P-15K-CHT Power: 2.2kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table MITSUBISHI FR-F740P-15K-CHT.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used MITSUBISHI Single phase 200V inverter. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor MITSUBISHI Single phase 200V inverter.
The installation of thermal relay, to avoid overheating and burn the braking resistor. MITSUBISHI inverter FR-F740 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 MITSUBISHI Single phase 200V inverter.
Why is the frequency of the inverter voltage proportional to the chhange?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the mmotor MITSUBISHI FR-F740P-15K-CHT FR-F740P-15K-CHT.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
