MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 2.2KW.
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 FX2N-32MT-D datasheet PDF catalog FX2N-32MT-D PDF datasheet FX2N-32MT-D
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 FX2N-32MT-D datasheet PDF catalog FX2N-32MT-D PDF datasheet.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
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 FX2N-32MT-D datasheet PDF catalog FX2N-32MT-D PDF datasheet.
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: 5.5kw.
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 (775K) and above capacity and above capacity FX2N-32MT-D datasheet PDF catalog FX2N-32MT-D PDF datasheet.
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 motorr power used to select the DC reactor FX2N-32MT-D datasheet PDF catalog FX2N-32MT-D PDF datasheet.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
