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.
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station.
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 inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 15.0kw.
SLD converter rated current: 31.0A.
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-F820-00167-2-60.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption
FR-F820-00167-2-60
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-F820-00167-2-60. Length: 30 meters.
Cable manufacturing specifications.
When there is no connection options, according to the table under the cable.
Using a parallel connection or a large size cable for connection between the terminal PG" and "SD" and the motor end encoder. "Power: 1 FR-F820-00167-2-60. 5kw.
Voltage: 200V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque. Power: 2.2kw.
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 thee FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-F820-00167-2-60.
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 motorr power used to select the DC reactor FR-F820-00167-2-60.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
