Power: 30kw.
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. (the IP55 series has a built-in DC reactor.)
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-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.75KW.
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-HEL-H30K.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter)
FR-HEL-H30K
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. "MITSUBISHI inverter FR-D740 series FR-HEL-H30K.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
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.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used FR-HEL-H30K. 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.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 110kw.
SLD converter rated current: 260A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteriistic drive motor FR-HEL-H30K.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-HEL-H30K.
