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 FX2NC-ENET-ADP PDF FX2NC-ENET-ADP
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 FX2NC-ENET-ADP PDF.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Power: 2.2kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FX2NC-ENET-ADP PDF.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) "MITSUBISHI inverter series: FR-A846.
Voltage level: three phase 400V.
Power: 7.5kw.
SLD converter rated current: 25.0A.
Structure and function: IP55 counterpart.
Type: CA.
Substrate coating: have.
Built in DC reactor.
Easy to operate, simple settings.
We have prepared a series of equipment and functions for you to work in any place to meet the life cycle of the product.
Allegedly, the motor power consumption accounted for about half of the total power generated by manufacturing industry consumption.
How to achieve energy efficiency in the plant without affecting the productivity.
Less energy consumption and more output FR-A800 series inverter will help you to have both fish and bear''s paw"
Parameters and frequency settings can be modified in the program.
Inverter control, for example, by the input signal to trigger the operation of the inverter, based on the operation of the innverter
The status of the signal output, as well as the monitor output and so on, can be customized according to the requirements FX2NC-ENET-ADP datasheet.
The control of each machine can be done separately by the frequency converter, and the controol of the dispersion is also carried out FX2NC-ENET-ADP datasheet.
Through combining with the real-time clock function can realize the automatic operation (in option FR-LU08). "
