"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
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. "
Power: 22kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MITSUBISHI FR-F740-18.5K-CHT. ) MITSUBISHI inverter series: FR-A800
FR-F740-18.5K-CHT
Voltage level: three phase 400V.
Power: 250kw.
SLD converter rated current: 610A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
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 MITSUBISHI FR-F740-18.5K-CHT.
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.
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 MITSUBISHI FR-F740-18.5K-CHT. MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.4KW.
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 inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 280KW.
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.
Why is the frequency of the inverter voltage proportionall to the change?
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 FR-F740-18 FR-F740-18.5K-CHT. 5K-CHT.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
