MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
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 FX3U-64MT/DS Hardware Edition Manual FX3U-64MT/DS USER'S MANUAL FX3U-64MT/DS
Why is the frequency of the inverter voltage proportional to the 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 motor FX3U-64MT/DS Hardware Edition Manual FX3U-64MT/DS USER'S MANUAL.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 90kw.
SLD converter rated current: 475A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel FX3U-64MT/DS Hardware Edition Manual FX3U-64MT/DS USER'S MANUAL. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 0.75kw.
SLD converter rated current: 7.7A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Compatibility with existing models.
Transducer installation size and FR-F700 (P) series of the same, so you do not need to worry about the replacement operation.
(rectifier separation type will vary)
Also, but also through thee use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station FX3U-64MT/DS Hardware Edition Manual FX3U-64MT/DS USER'S MANUAL.
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same timme, used in the control of the external machine FX3U-64MT/DS Hardware Edition Manual FX3U-64MT/DS USER'S MANUAL.
No external PID controller is used to control the external machine, so the system cost can be reduced.
