MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.4KW.
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.
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.
Length: 5 meters.
Operation panel or parameter unit connection line. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 90kw.
SLD converter rated current: 216A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup FR-D720S-0
FR-D720S-0.4K4K.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor FR-D720S-0.4K.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor) FR-D720S-0.4K.
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving. "MITSUBISHI inverter series: FR-A846.
Voltage level: three phase 400V.
Power: 1.5kw.
SLD converter rated current: 5.2A.
Structure and function: IP55 counterpart.
Type: CA.
Substrate coating: have.
Built in DC reactor.
Easy to operate, simple settings.
We have prepared a series of equipment and functions for you to work in any place to meet the life cycle of the product.
Allegedly, the motor power consumption accounted for about half of the total power generated by manufacturing industry consumption.
How to achieve energy efficiency in the plant without affecting the productivity.
Less energy consumption and more output FR-A800 series inverter will help you to have both fish and bear''s paw"
Parameters and frequency settings can be modified in the program.
Inverter control, for example, by the input signal to trigger the operation of the inverter, based on the operatioon of the inverter
The status of the signal output, as well as the monitor output and so on, can be customized according to the requirements FR-D720S-0.4K.
The control of each machine can be done separately by the frequency converter, and the controol of the dispersion is also carried out FR-D720S-0.4K.
Through combining with the real-time clock function can realize the automatic operation (in option FR-LU08). "
