Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits MITSUBISHI MM-EFS151M4 MM-EFS151M4
Low noise.
No surge current.
Reduce motor loss (standard motor). MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 3.7KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus MITSUBISHI MM-EFS151M4.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy.
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure MITSUBISHI MM-EFS151M4.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V MITSUBISHI Three phase 400V grade frequency converter.
Frequency converter capacity: 7.5KW.
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%) MITSUBISHI Three phase 400V grade frequency converter.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical andd electrical MITSUBISHI Three phase 400V grade frequency converter MM-EFS151M4.
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 MITSUBISHI MM-EFS151M4.
