MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 185KW.
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 MITSUBISHI FR-F842-12120-2-60.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FR-F842-12120-2-60
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 saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI FR-F842-12120-2-60. MITSUBISHI inverter series: FR-F842.
Voltage level: three phase 400V.
Power: 400kw.
SLD converter rated current: 866A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
Energy saving by high efficiency motor.
Reduce standby power consumption MITSUBISHI FR-F842-12120-2-60.
DC24V external power supply, the input MC signal can be stopped after the motor for the OFF, in the motor drive for the ON.
Standby power management can be carried out by means of frequency converter to realize the power consumption reduction of standby time.
According to the temperature of the inverter cooling fan, the operation of the inverter can be controlled MITSUBISHI Three phase 400V grade frequency converter.
According to the operating conditions of the inverter cooling fan output the corresponding signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation MITSUBISHI Three phase 400V grade frequency converter.
Can reduce the power consumption in the stop. Power: 5.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted MITSUBISHI Three phase 400V grade frequency converter.
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 lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 3300 degrees C or higher, it is necessary to take protective measures and cooling FR-F842-12120-2-60.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between thhe short circuit chip, in addition to connecting the DC reactor MITSUBISHI FR-F842-12120-2-60.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
