MITSUBISHI FR-F740-18.5K-CHT Product information and technical parameters：
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740-18.5K-CHT
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
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.
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 fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "

Power: 150kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits FR-F740-18 FR-F740-18.5K-CHT5K-CHT.
Low noise.
No surge current.
Reduce motor loss (standard motor). Power: 11kw.
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 FR-F740-18.5K-CHT.
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-E720 series.
Voltage level: 3 phase 200V FR-F740-18.5K-CHT.
Frequency converter capacity: 1.5KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy.
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure.
When using variable frequency control, if the flow rate is redduced, the speed of the pump or fan can be reduced to meet the requirements FR-F740-18.5K-CHT. Superior high efficiency IPM motor.
Output power: 37kw.
Rated speed: 1500r/min.
Voltage level: 400V.
IPM motor MM-EFS series can not be used to run the poower frequency power FR-F740-18.5K-CHT.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time.
