MITSUBISHI FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet

MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.4KW.
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 FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet FR-A740-11K-CHT 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 omitted FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet.
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.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 75KW.
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.
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).
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. MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 90kw.
SLD converter rated current: 475A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equuipment) FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet.
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network FR-A740-11K-CHT datasheet PDF catalog FR-A740-11K-CHT PDF datasheet.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
