MITSUBISHI inverter FR-D720S series.
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 Communication Module User's Manual FX-485ADP 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 Communication Module User's 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 MITSUBISHI Communication Module User's Manual. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
The use of frequency converter motor is in order to speed, and reduce the starting current FX-485ADP User's Manual.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification FX-485ADP User's Manual.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter FX-485ADP User's Manual.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 1.5kw.
SLD converter rated current: 5.2A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Excellent drive performance.
FR-A800 series equipped with the latest high-speed processor. Has better control performance and response speed,
Products to ensure stable and accurate operation in a wide variety of applications.
Enhanced real-time sensorless vector control and vector control functions, can meet the needs of vvarious kinds of machinery and equipment FX-485ADP Manual.
For paper, textile, wire, a variety of tape and other products of the extension of the machine processing, linear speed control is essential.
It can respond quicckly to the change of production line speed and avoid the phenomenon of uneven winding MITSUBISHI Communication Module User's Manual.
This helps to achieve a stable supply of high quality products.
