Power: 11kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost MITSUBISHI INVERTER PLC FUNCTION PROGRAMMING MANUAL.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving FR-A720-0.75K Power: 400kw.
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 inverter FR-F740 series MITSUBISHI INVERTER PLC FUNCTION PROGRAMMING MANUAL.
Voltage level: three phase 400V.
Frequency converter capacity: 355KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor MITSUBISHI INVERTER PLC FUNCTION PROGRAMMING MANUAL.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FR-A720-0.75K PLC FUNCTION PROGRAMMING MANUAL.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity FR-A720-0.75K PLC FUNCTION PROGRAMMING MANUAL. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 15KW.
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 FR-A720-0.75K PLC FUNCTION PROGRAMMING MANUAL.
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 regulatinng 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 processs of closure MITSUBISHI INVERTER PLC FUNCTION PROGRAMMING MANUAL FR-A720-0.75K Manual.
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.
