MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 250KW.
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.
Parameter setting can be carried out without the power supply of the inverter.Power: 22kw.
Voltage: 200V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V MITSUBISHI FR-A740-250K-CHT.
Power: 15kw.
SLD converter rated current: 77A.
Structure and function: Standard model
FR-A740-250K-CHT
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive MITSUBISHI FR-A740-250K-CHT.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. "MITSUBISHI inverter FR-E720S series MITSUBISHI FR-A740-250K-CHT.
Voltage level: single phase 200V.
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 MITSUBISHI 3 phase 400V converter.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) MITSUBISHI 3 phase 400V converter.
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.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor MITSUBISHI 3 phaase 400V converter FR-A740-250K-CHT. "Power: 45kw.
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 mmotor power used to select AC reactor MITSUBISHI FR-A740-250K-CHT.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
