MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 220KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc..
These frequencies have their advantages and disadvantages, and should be selected according to the actual needs.
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.
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes FR-F740-S220K-CHT.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection)
FR-F740-S220K-CHT
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall FR-F740-S220K-CHT. MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 160kw.
SLD converter rated current: 432A.
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 FR-F740-S220K-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. Power: 15kw.
Voltage: 200V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
MMotor suitable for 5 FR-F740-S220K-CHT. 5 to 37kW. Power: 37kw.
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 mmotor power used to select AC reactor FR-F740-S220K-CHT.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
