Power: 75kw.
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 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.)
MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 5.5kw.
SLD converter rated current: 12.6A.
Structure and function: Standard model.
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 MITSUBISHI FR-HAL-H75K.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption
FR-HAL-H75K
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 MITSUBISHI FR-HAL-H75K. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 37kw.
SLD converter rated current: 187A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings MITSUBISHI FR-HAL-H75K.
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.
The number of power frequency driven pump, according to the automatic adjustment of water MITSUBISHI Install a compatible option.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units MITSUBISHI Install a compatible option.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. 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 Install a compatible option. .
These frequencies have their advantages and disadvantages, and should be selected according to the actuual needs FR-HAL-H75K.
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 frequeency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions MITSUBISHI FR-HAL-H75K.
