MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 18.5kw.
SLD converter rated current: 93A.
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 (genneral load) rating, HD (weight) FX1S-20MT-ES/UL.
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) FX1S-20MT-ES/UL.
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 FX1S-20MT-ES/UL.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0 MITSUBISHI FX1S-20MT-ES/UL.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 FX1S-20MT-ES/UL. 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 MITSUBISHI FX1S-20MT-ES/UL.
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.
Max input / output points: 20 points.
Supply voltage: 100 - 240VAC.
Input points: 12 points.
Output points: 8 points.
Output type: Transistor (source).
Power consumption (W): 7.
Weight (kg):0.3.
Size (WxHxD) mm:75x90x75.
Host has 10 points (6I/4O), 14 points (8I/6O), 20 points (12I/8O), 30 points (16I/14O) of 4 types.
This type of PLC is mainly used in all of the digital input, digital output control point of the device.
Can be directly connected to the 220V city power, built-in 8K step EEPROM memory, no battery, easy to maintain.
The series transistor output (MT) of the PLC, can be output 2 100KHz pulse, direct drive servo or stepper motor.<
The series PLC can not be brought with the expansion module, but can be installed by the BD board to extend a small amount of I/O FX1S-20MT-ES/UL.
The series 1N through the installation of BD series PLC board, can achieve RS232, RS485, RS422 communication.
