MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 0.75kw.
SLD converter rated current: 2.3A.
Structure and function: Standard model FR-A5AX PDF.
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-A5AX
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 FR-A5AX PDF.
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: 1.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted FR-A5AX PDF.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will leadd to overheating of the brake resistor FR-A5AX Manual.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table MITSUBISHI INSTRUCTION MANUAL.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate MITSUBISHI INSTRUCTION MANUAL.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor.
The installation of thermal relay, to avoid overheating and burn the braking resistor. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 37KW MITSUBISHI INSTRUCTION MANUAL.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the ddetection unit FR-A5AX INSTRUCTION MANUAL.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy savving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on FR-A5AX Manual.
