MITSUBISHI FR-A846-00023-2-60 PDF catalog FR-A846-00023-2-60 datasheet PDF datasheet

MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
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 FR-A846-00023-2-60 PDF datasheet.
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) FR-A846-00023-2-60
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 FR-A846-00023-2-60 PDF datasheet. MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 90KW.
Inverter general area of domestic enterprises to occupy more than 80% of the market share,
Production of frequency converter, motor soft starter and other industrial automation control of the manufacturers, the use of heavy-duty design products,
Overload capacity, with super large start and running capacity, improve the automatic detection, protection and control performance,
Can start and control any type of heavy duty motor,
Products have been widely used in metallurgy, mining, paper, chemicals, building materials, machinery, electricity, and construction systems and other industrial transmission areas FR-A846-00023-2-60 PDF datasheet. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 2.2KW.
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. 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-A846-00023-2-60 PDF catalog.
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 FR-A846-00023-2-60 PDF catalog.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
