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 FR-E720-3 FR-E720-3.7K7K Instruction manual.
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 FR-E720-3.7K Instruction manual.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Used to reduce radio noise.MITSUBISHI inverter FR-E740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 0.75KW.
Allow short-time overload (200% 3S).
The machine itself does not need to purchase another operating panel FR-E720-3.7K Instruction manual.
Provide USB interface to connect with the computer, you can use the FRConfigurator software to set the parameters of the inverter or monitor.
Inverter surface with PU interface, FR-E500 operating panel can be directly connected to the E700 series. The installation dimensions are in full agreement with FR-E500.
Allow side by side installation, saving installation space
Simple maintenance: equipped with comb type wiring board, wiring more convenient, the replacement of the same series inverter, no stitches, as long as the original inverter control terminal. Connecting cable for handheld RH GOT and PLC.
Cable length: 1.5 meters.
Application: RS-422 connection (FX series). "MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
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 "inverterr" (inverter) FR-E720-3.7K Manual .
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 invertter FR-E720-3.7K Manual .
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "
