MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 15KW.
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.
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 30KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions MITSUBISHI FR-E720-15K.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder
FR-E720-15K
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc MITSUBISHI FR-E720-15K. ) and torque control. Power: 280kw.
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 FR-E720-15K.
Low noise.
No surge current.
Reduce motor loss (standard motor). MITSUBISHI inverter FR-F720 series FR-E720-15K MITSUBISHI.
Voltage level: three phase 200V.
Frequency converter capacity: 55KW.
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-E720-15K MITSUBISHI.
For the requirements of relatively high precision, even if the load changes are also required to opperate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) FR-E720-15K MITSUBISHI FR-E720-15K.
If the given acceleration time is too short, the output frequency of the inverter is far more than thhe change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall MITSUBISHI FR-E720-15K.
