MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible MITSUBISHI FR-E740-0 FR-E740-0.4K-CHT4K-CHT Instruction manual.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced MITSUBISHI FR-E740-0.4K-CHT Instruction manual.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Can be isolated to obtain DC24/48/100V, AC100/200V input signal.Parameter setting can be carried out without the power supply of the inverter.MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 5.5kw.
SLD converter rated current: 12 MITSUBISHI FR-E740-0.4K-CHT Instruction manual. 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.
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: 15kw.
Voltage: 400V.
There are 100% braking torque output in continuuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control FR-E740-0.4K-CHT Manual .
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost FR-E740-0.4K-CHT Manual .
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
