Power: 110kw.
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.)

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 MITSUBISHI FR-HAL-H110K
FR-HAL-H110K
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 MITSUBISHI FR-HAL-H110K.
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. "MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.1KW.
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 MITSUBISHI FR-HAL-H110K.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FR-HAL-H110K MITSUBISHI.
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 FR-HAL-H110K MITSUBISHI.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V FR-HAL-H110K MITSUBISHI.
Frequency converter capacity: 7.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rateed current, therefore, the impact on the mechanical and electrical FR-HAL-H110K.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120%% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load MITSUBISHI FR-HAL-H110K.
