MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 37KW.
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 FR-F740P-30K-CHT BASIC Manual FR-F740P-30K-CHT Instruction manual.
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) FR-F740P-30K-CHT
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 FR-F740P-30K-CHT BASIC Manual FR-F740P-30K-CHT Instruction manual. Voltage level: three phase 400V.
Applicable motor capacity: 500kw.
Substrate coating: have.
Built in DC reactor.
The operating frequency of the fixed alternating current is converted to DC power. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 3.7kw.
SLD converter rated current: 8.3A.
Structure and function: Standard model FR-F740P-30K-CHT BASIC Manual FR-F740P-30K-CHT Instruction manual.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. Power: 0.4kw.
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) andd above capacity and above capacity FR-F740P-30K-CHT BASIC Manual FR-F740P-30K-CHT Instruction manual.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr power used to select the DC reactor FR-F740P-30K-CHT BASIC Manual FR-F740P-30K-CHT Instruction manual.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
