MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.4KW.
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.
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.
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.
Power: 55kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost FR-E720-0.4K.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving
FR-E720-0.4K 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 FR-E720-0.4K.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits.
Low noise.
No surge current.
Reduce motor loss (standard motor). MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 280kw.
SLD converter rated current: 610A.
Structure and function: Standard model.
Type: CA FR-E720-0.4K.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characterisstic drive motor FR-E720-0.4K.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-E720-0.4K.
