FR-A820-7.5K-1(FR-A820-00490-2-60) Three phase 200V grade frequency converter

"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification FR-A820-7.5K-1(FR-A820-00490-2-60).
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FR-A820-7.5K-1(FR-A820-00490-2-60)
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "MITSUBISHI inverter series: FR-F840 FR-A820-7.5K-1(FR-A820-00490-2-60).
Voltage level: three phase 400V.
Power: 30kw.
SLD converter rated current: 62.0A.
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.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption FR-A820-7.5K-1(FR-A820-00490-2-60).
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. Power: 15kw.
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 1.5kw.
SLD converter rated current: 10.5A.
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 varry)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station FR-A820-7.5K-1(FR-A820-00490-2-60).
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-A820-7.5K-1(FR-A820-00490-2-60).
No external PID controller is used to control the external machine, so the system cost can be reduced.
