MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 132KW.
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..
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 inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 18.5kw.
SLD converter rated current: 93A.
Structure and function: Standard model.
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 FR-F740-S132K-CHT MITSUBISHI
FR-F740-S132K-CHT
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
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 FR-F740-S132K-CHT MITSUBISHI.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. Superior high efficiency IPM motor.
Output power: 7.5kw.
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.
1 inverters can not connect multiple IPM motors at the same time FR-F740-S132K-CHT MITSUBISHI. Power: 15kw.
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
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 thhe rated current, therefore, the impact on the mechanical and electrical FR-F740-S132K-CHT.
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 FR-F740-S132K-CHT.
