FR-A740-45K-CHT MITSUBISHI FR-A740-45K-CHT
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-A740-45K-CHT
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 45KW.
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-F840.
Voltage level: three phase 400V.
Power: 280kw.
SLD converter rated current: 610A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup MITSUBISHI FR-A740-45K-CHT FR-A740-45K-CHT
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor MITSUBISHI FR-A740-45K-CHT.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving MITSUBISHI FR-A740-45K-CHT. Power: 30kw.
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.
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. "Power: 30kw.
Voltage: 200V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of thhe motor FR-A740-45K-CHT.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time connsumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy FR-A740-45K-CHT. "
