FR-F740-S280K-CHT MITSUBISHI FR-F740-S280K-CHT 3 phase 400V converter
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740-S280K-CHT
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 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.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.

Power: 75kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available MITSUBISHI FR-F740-S280K-CHT.
Please select according to the required braking torque. Superior high efficiency IPM motor FR-F740-S280K-CHT
Output power: 15kw.
Rated speed: 1500r/min.
Voltage level: 200V.
IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V MITSUBISHI FR-F740-S280K-CHT.
Frequency converter capacity: 15KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder MITSUBISHI FR-F740-S280K-CHT.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc MITSUBISHI 3 phase 400V converter. ) and torque control. MITSUBISHI inverter FR-D720S series MITSUBISHI 3 phase 400V converter.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation MITSUBISHI 3 phase 400V converter. To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitteed FR-F740-S280K-CHT.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study MITSUBISHI FR-F740-S280K-CHT.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
