FR-F720-30K | MITSUBISHI 3 phase 200V converter FR-F720-30K
Brand: MITSUBISHI
Name: 3 phase 200V converter
Model: FR-F720-30K
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall.

"Power: 55kw.
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 the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit MITSUBISHI FR-F720-30K.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed 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-F720-30K "Power: 3.7kw.
Voltage: 200V.
Purpose: high frequency braking resistor MITSUBISHI FR-F720-30K.
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: 55kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current MITSUBISHI FR-F720-30K.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor FR-F720-30K MITSUBISHI. (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 FR-F720-30K MITSUBISHI. ) Superior high efficiency IPM motor.
Output power: 37kw.
Rated speed: 1500r/min.
Voltage level: 400V.
IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m FR-F720-30K MITSUBISHI.
1 inverters can not connect multiple IPMM motors at the same time FR-F720-30K. Power: 30kw.
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 mmotor power used to select AC reactor MITSUBISHI FR-F720-30K.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
