Power: 0.4kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)

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 MITSUBISHI FR-HEL-H0.4K.
(rectifier separation type will vary)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station
FR-HEL-H0.4K
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same time, used in the control of the external machine.
No external PID controller is used to control the external machine, so the system cost can be reduced MITSUBISHI FR-HEL-H0.4K. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 0.75kw.
SLD converter rated current: 2.3A.
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 FR-HEL-H0.4K.
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 Relay output module.
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 Relay output module. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 315KW.
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 MITSUBISHI Relay output module.
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-HEL-H0 FR-HEL-H0.4K. 4K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
