MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 45kw.
SLD converter rated current: 233A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment).
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
Power: 55kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor MITSUBISHI FR-A820-45K-1(FR-A820-02330-2-60). (the IP55 series has a built-in DC reactor
FR-A820-45K-1(FR-A820-02330-2-60))
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 18.5KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment MITSUBISHI FR-A820-45K-1(FR-A820-02330-2-60).
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
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.
With torque control mode,
And in the speed control mode can use the torque limit function MITSUBISHI FR-A820-45K-1(FR-A820-02330-2-60).
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 FR-A820-45K-1(FR-A820-02330-2-60) MITSUBISHI. ) and torque control. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 11KW FR-A820-45K-1(FR-A820-02330-2-60) MITSUBISHI.
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 FR-A820-45K-1(FR-A820-02330-2-60) MITSUBISHI.
Speed control method of fan and pump equipment traditional by reegulating 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 processs of closure MITSUBISHI FR-A820-45K-1(FR-A820-02330-2-60) FR-A820-45K-1(FR-A820-02330-2-60).
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.
