MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 11KW.
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-E5NFS-2 FR-E5NFS-2.2K2K Manual FR-E5NFS-2 FR-E5NFS-2.2K Manual FR-E5NFS-2.2K Safety instruction. 2K Safety instruction. Function extension board for RS-485 communication.
No DC24V consumption, do not take up input and output. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 162KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment FR-E5NFS-2.2K Manual FR-E5NFS-2.2K Safety instruction.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on. Can be isolated to obtain DC24/48/100V, AC100/200V input signal.Power: 22kw.
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-A840-021160 (75K) and above capacity and above capacity FR-E5NFS-2.2K Manual FR-E5NFS-2.2K Safety instruction.
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 FR-E5NFS-2.2K Manual FR-E5NFS-2.2K Safety instruction.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
