MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 30kw.
SLD converter rated current: 154A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment).
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 2.2kw.
SLD converter rated current: 5.2A.
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 FR-A820-30K-1(FR-A820-01540-2-60).
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption
FR-A820-30K-1(FR-A820-01540-2-60)
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.
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 FR-A820-30K-1(FR-A820-01540-2-60). 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 FR-A820-30K-1(FR-A820-01540-2-60). (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.) MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 2.2kw.
SLD converter rated current: 16.7A.
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 vaary)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station FR-A820-30K-1(FR-A820-01540-2-60).
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 FR-A820-30K-1(FR-A820-01540-2-60).
No external PID controller is used to control the external machine, so the system cost can be reduced.
