MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 1.5KW.
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.
High level driving performance.
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder.
And in the speed control mode can use the torque limit function.
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control.
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 11KW.
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-A740-1.5K-CHT.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter)
FR-A740-1.5K-CHT
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "Power: 355kw FR-A740-1.5K-CHT.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V FR-A740-1.5K-CHT.
Power: 0.75kw.
SLD converter rated current: 2.3A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 450kw.
SLD converter rated current: 1094A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor.
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 otther manufacturers of induction motor and PM motor FR-A740-1.5K-CHT.
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%,
EEven after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely FR-A740-1.5K-CHT.
