Inverter output for the PWM wave, containing more harmonic.
Frequency conversion power sensor through the input voltage and current signals to exchange sampling,
Sampling value through cable, optical fiber and other transmission systems and digital input frequency conversion power analyzer,
The sampling value of the voltage and current is calculated by the digital input frequency conversion power analyzer,
It can obtain the parameters such as voltage effective value, current effective value, fundamental wave voltage, fundamental current, harmonic voltage, harmonic current, active power, fundamental wave power and harmonic power FR-F820-00490-2-60 datasheet PDF catalog FR-F820-00490-2-60 PDF datasheet FR-F820-00490-2-60 datasheet PDF catalog FR-F820-00490-2-60 PDF datasheet FR-F820-00490-2-60 Power: 22kw.
Voltage: 200V.
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.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving FR-F820-00490-2-60 datasheet PDF catalog FR-F820-00490-2-60 PDF datasheet. 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.
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 exitt 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 FR-F820-00490-2-60 datasheet PDF catalog FR-F820-00490-2-60 PDF datasheet FR-F820-00490-2-60 datasheet PDF catalog FR-F820-00490-2-60 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.
