MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 90KW.
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 FX1S-30MT-DSS datasheet PDF catalog FX1S-30MT-DSS PDF datasheet.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FX1S-30MT-DSS
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 FX1S-30MT-DSS datasheet PDF catalog FX1S-30MT-DSS PDF datasheet. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.Power: 560kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current FX1S-30MT-DSS datasheet PDF catalog FX1S-30MT-DSS PDF datasheet.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) 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. (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.) Function expansion board for RS-232C communication.Power: 22kw.
