MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.75KW.
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-A820-3 FR-A820-3.7K-17K-1 Manual . 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-A820-3.7K-1 Manual .
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-A820-3.7K-1 Manual . Max input / output points: 20 points.
Supply voltage: 100 - 240VAC.
Input points: 12 points.
Output points: 8 points.
Output type: relay.
Power consumption (W): 20.
Weight (kg):0.4.
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 MITSUBISHI FR-A820-3.7K-1 Programming Manual.
This type of PLC is mainly used in all of the digital input, digital output control point of the device MITSUBISHI FR-A820-3.7K-1 Programming Manual.
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 MITSUBISHI FR-A820-3.7K-1 Programming Manual.
The series 1N through the installation of BD series PLC board, can achieve RS232, RS485, RS422 communication. Power: 11kw.
Voltage: 200V.
There are 100% braking torque output in contiinuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control FR-A820-3.7K-1 PLC FUNCTION.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost FR-A820-3.7K-1 Manual .
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
