MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 5.5KW.
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 MITSUBISHI MM-EFS221M MM-EFS221M
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 MITSUBISHI MM-EFS221M.
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. Power: 160kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function MITSUBISHI MM-EFS221M. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
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 MM-EFS221M MITSUBISHI.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) MM-EFS221M 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 MM-EFS221M MITSUBISHI. "Power: 7.5kw.
Voltage: 200V.
There are 100% braking torque output in conttinuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control MM-EFS221M.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost MITSUBISHI MM-EFS221M.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
