MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 90kw.
SLD converter rated current: 475A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment).
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits MITSUBISHI FR-A820-90K-1(FR-A820-04750-2-60)
FR-A820-90K-1(FR-A820-04750-2-60)
Low noise.
No surge current.
Reduce motor loss (standard motor). Uses: for external BCD or binary digital signal to do the frequency of a given.
Applicable frequency converter: FR-A700, FR-F700, FR-E700"Length: 5 meters.
Cable manufacturing specifications.
When there is no connection options, according to the table under the cable MITSUBISHI FR-A820-90K-1(FR-A820-04750-2-60).
Using a parallel connection or a large size cable for connection between the terminal PG" and "SD" and the motor end encoder. "Power: 18.5kw.
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 MITSUBISHI FR-A820-90K-1(FR-A820-04750-2-60).
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 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 MITSUBISHI IP55 converter built-in DC reactor. ) MITSUBISHI inverter FR-A740 series MITSUBISHI IP55 converter built-in DC reactor.
Voltage level: 3 phase 400V.
Frequency converter capacity: 162KW.
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 IP55 converter built-in DC reactor.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by thee 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 MITSUBISHI FR-A820-90K-1(FR-A820-04750-2-60) FR-A820-90K-1(FR-A820-04750-2-60).
