MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 7.5KW.
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.
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 15KW.
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 MITSUBISHI FR-A720-7.5K.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter)
FR-A720-7.5K
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. "MITSUBISHI inverter FR-D720 series MITSUBISHI FR-A720-7.5K.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation MITSUBISHI FR-A720-7.5K. "MITSUBISHI inverter series: FR-A846.

Built in DC reactor.
Easy to operate, simple settings.
We have prepared a series of equipment and functions for you to work in any place to meet the life cycle of the product.
Allegedly, the motor power consumption accounted for about half of the total power generated by manufacturing industry consumption.
How to achieve energy efficiency in the plant without affecting the productivity.
Less energy consumption and more output FR-A800 series inverter will help you to have both fish and bear''s paw"
Parameters and frequency settings can be modified in the program.
Inverter control, for example, by the input signal to trigger the operation of the inverter, based on the operatiion of the inverter
The status of the signal output, as well as the monitor output and so on, can be customized according to the requirements FR-A720-7.5K.
The control of each machine can be done separately by the frequency converter, and the controol of the dispersion is also carried out FR-A720-7.5K.
Through combining with the real-time clock function can realize the automatic operation (in option FR-LU08). "
