MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 75KW.
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.
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).
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.

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 MITSUBISHI FR-F720-S75K.
Allegedly, the motor power consumption accounted for about half of the total power generated by manufacturing industry consumption
FR-F720-S75K
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 MITSUBISHI FR-F720-S75K.
Inverter control, for example, by the input signal to trigger the operation of the inverter, based on the operation 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.
The control of each machine can be done separately by the frequency converter, and the control of the dispersion is also carried out MITSUBISHI FR-F720-S75K.
Through combining with the real-time clock function can realize the automatic operation (in option FR-LU08). "MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 3.7kw MITSUBISHI 3 phase 400V converter.
SLD converter rated current: 8.3A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed MITSUBISHI 3 phase 400V converter.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor MITSUBISHI 3 phase 400V converter.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 250KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor.
Why is the frequency of the inverter voltage proportional to thhe change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the mmotor MITSUBISHI FR-F720-S75K FR-F720-S75K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
