MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 90KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on.
MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible FR-A740-90K-CHT
FR-A740-90K-CHT
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced FR-A740-90K-CHT.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 355kw.
SLD converter rated current: 866A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor FR-A740-90K-CHT.
Advanced auto tuning function.
The newly developed PM motor auto tuning feature can be used to operate other manufacturers of PM motors (Yong Ci synchronous motors) in the sensorless state.
Not only can drive MITSUBISHI induction motor and PM motor, but also can drive other manufacturers of induction motor and PM motor.
This means that you can reduce the cost of inventory and supplies.
If the PM motor is produced by a IPM motor or other company using MM-CF, the starting torque is limited to 50%,
Even after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification FR-A740-90K-CHT.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixeed frequency and a certain voltage of the inverter FR-A740-90K-CHT.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
