MITSUBISHI FR-A740-55K-CHT Product information and technical parameters:
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-A740-55K-CHT
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 55KW.
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 detection unit.
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 inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 2.2kw.
SLD converter rated current: 16.7A.
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) MITSUBISHI FR-A740-55K-CHT FR-A740-55K-CHT
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 MITSUBISHI FR-A740-55K-CHT.
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: 1.5kw.
Voltage: 200V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor MITSUBISHI FR-A740-55K-CHT.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 0.75kw.
SLD converter rated current: 2.3A.
Structure and function: Standard model.
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 conssumption FR-A740-55K-CHT.
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.
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 FR-A740-55K-CHT.
