MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 0.4kw.
SLD converter rated current: 2.3A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Excellent drive performance.
FR-A800 series equipped with the latest high-speed processor. Has better control performance and response speed,
Products to ensure stable and accurate operation in a wide variety of applications.
Enhanced real-time sensorless vector control and vector control functions, can meet the needs of various kinds of machinery and equipment.
For paper, textile, wire, a variety of tape and other products of the extension of the machine processing, linear speed control is essential.
It can respond quickly to the change of production line speed and avoid the phenomenon of uneven winding.
This helps to achieve a stable supply of high quality products.

Power: 75kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available FR-A840-00023-2-60.
Please select according to the required braking torque. MITSUBISHI inverter FR-D720 series FR-A840-00023-2-60
Voltage level: three phase 200V.
Frequency converter capacity: 0.4KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-A840-00023-2-60 FR-A840-00023-2-60. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 5.5KW.
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 eequipment 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 processs of closure FR-A840-00023-2-60 FR-A840-00023-2-60.
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.
