FR-F842-07700-2-60 MITSUBISHI Three phase 400V grade frequency converter MITSUBISHI FR-F842-07700-2-60

MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) MITSUBISHI FR-F842-07700-2-60 FR-F842-07700-2-60
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load MITSUBISHI FR-F842-07700-2-60. Power: 7.5kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost MITSUBISHI FR-F842-07700-2-60.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. Power: 355kw.
Purpose: to suppress the power harmonics MITSUBISHI Three phase 400V grade frequency converter.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current MITSUBISHI Three phase 400V grade frequency converter.
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: 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 MITSUBISHI Three phase 400V grade frequency converter.
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: 55kw.
SLD converter rated current: 116A.
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.
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.

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) FR-F842-07700-2-60.
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving MITSUBISHI FR-F842-07700-2-60.
