FR-A720-75K MITSUBISHI 3 phase 400V converter FR-A720-75K

Brand: MITSUBISHI
Name: 3 phase 200V converter
Model: FR-A720-7.5K
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-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible MITSUBISHI FR-A720-7 FR-A720-7.5K5K.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced MITSUBISHI FR-A720-7.5K.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 11KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) MITSUBISHI FR-A720-7.5K.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical MITSUBISHI 3 phase 400V converter.
The inverter drive can be smoothly start (start time longer) MITSUBISHI 3 phase 400V converter.
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load. Superior high efficiency IPM motor MITSUBISHI 3 phase 400V converter.
Output power: 11kw.
Rated speed: 1500r/min.
Voltage level: 400V.
IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time. Power: 0.75kw.
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-AA820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-A720-7.5K.
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 MITSUBISHI FR-A720-7.5K.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
