MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 15kw.
SLD converter rated current: 77A.
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 equipment).
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.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 315kw.
SLD converter rated current: 770A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor.
Advanced auto tuning function.
The newly developed PM motor auto tuning feature can be used to operate other manufacturers of PM motors (Yong Ci synchronous motors) in the sensorless state FR-A820-15K-1(FR-A820-00770-2-60)
FR-A820-15K-1(FR-A820-00770-2-60)
Not only can drive MITSUBISHI induction motor and PM motor, but also can drive other manufacturers of induction motor and PM motor.
This means that you can reduce the cost of inventory and supplies.
If the PM motor is produced by a IPM motor or other company using MM-CF, the starting torque is limited to 50%,
Even after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely FR-A820-15K-1(FR-A820-00770-2-60). MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 1.5KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion FR-A820-15K-1(FR-A820-00770-2-60).
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. 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.
Itt 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 FR-A820-15K-1(FR-A820-00770-2-60).
Although the technology is not yet mature, but still attract a large number of scholars in-depth study FR-A820-15K-1(FR-A820-00770-2-60).
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
