MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 560KW.
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 FX3U-422-BD datasheet PDF catalog FX3U-422-BD PDF datasheet FX3U-422-BD
Why is the frequency of the inverter voltage proportional 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 motor FX3U-422-BD datasheet PDF catalog FX3U-422-BD PDF datasheet.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. MITSUBISHI inverter series: FR-F842.
Voltage level: three phase 400V.
Power: 450kw.
SLD converter rated current: 962A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
Energy saving by high efficiency motor FX3U-422-BD datasheet PDF catalog FX3U-422-BD PDF datasheet.
Reduce standby power consumption.
DC24V external power supply, the input MC signal can be stopped after the motor for the OFF, in the motor drive for the ON.
Standby power management can be carried out by means of frequency converter to realize the power consumption reduction of standby time.
According to the temperature of the inverter cooling fan, the operation of the inverter can be controlled.
According to the operating conditions of the inverter cooling fan output the corresponding signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation.
Can reduce the power consumption in the stop. Power: 11kw.
Voltage: 200V.
There are 100% braking torque output in continuous regeneration, which can corresppond to the continuous regeneration operation of the pipeline control FX3U-422-BD datasheet PDF catalog FX3U-422-BD PDF datasheet.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost FX3U-422-BD datasheet PDF catalog FX3U-422-BD PDF datasheet.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
