MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 75kw.
SLD converter rated current: 380A.
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: 11kw.
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.
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 MITSUBISHI FR-A820-75K-1(FR-A820-03800-2-60). ) Applicable motor capacity: 1
FR-A820-75K-1(FR-A820-03800-2-60)5KW.
Rated current: 1.2A.
Power supply voltage: three phase 400V.
Frequency converter and GOT supporting the use, to achieve a higher price.
SIMPLE GOT series can be directly connected to the IS70 series inverter.
GOT can be directly connected with the inverter. After connecting the two, the communication parameters can be automatically set MITSUBISHI FR-A820-75K-1(FR-A820-03800-2-60).
In addition, the software can display the soft component of the control function in the GOT, even when the multi frequency converter is connected,
Can also be unified management with 1 GOT.
Through the GOT screen to create software to import the picture data after the GOT,
Only use RS-422 connection GOT and frequency converter,
Can change the inverter speed / direction, monitoring the output frequency / output current and set a variety of parameters MITSUBISHI FR-A820-75K-1(FR-A820-03800-2-60). MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 110KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc MITSUBISHI IP55 converter built-in DC reactor MITSUBISHI IP55 converter built-in DC reactor. .
These frequencies have their advantages and disadvantages, and should be selected according to the actual needs.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions MITSUBISHI IP55 converter built-in DC reactor. Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wavee filter is installed to the output terminal of the inverter FR-A820-75K-1(FR-A820-03800-2-60).
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operationnal characteristics of the sine wave power driver, can provide the following benefits MITSUBISHI FR-A820-75K-1(FR-A820-03800-2-60).
Low noise.
No surge current.
Reduce motor loss (standard motor).
