FR-F720-22K 3 phase 400V converter MITSUBISHI FR-F720-22K 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
Brand:
MITSUBISHI
Name: 3 phase 200V converter
Model: FR-F720-2.2K
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 2.2KW.
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%).
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.

Power: 37kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
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 MITSUBISHI FR-F720-2.2K. (the IP55 series has a built-in DC reactor FR-F720-2.2K)
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.) MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 90KW.
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 FR-F720-2.2K. .
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 FR-F720-2.2K. MITSUBISHI inverter series: FR-F820 MITSUBISHI 3 phase 400V converter.
Voltage level: three phase 200V.
Power: 55kw.
SLD converter rated current: 316A.
Structure and function: Standard model MITSUBISHI 3 phase 400V converter.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive MITSUBISHI 3 phase 400V converter.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. Power: 7.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to rreach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-F720-2.2K.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between thhe short circuit chip, in addition to connecting the DC reactor MITSUBISHI FR-F720-2.2K.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
