MITSUBISHI FR-D740-22K-CHT The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft 3 phase 400V converter FR-D740-22K-CHT

Power: 7.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor FR-D740-2.2K-CHT.
The utilization rrate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-D740-2.2K-CHT.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor FR-D740-2.2K-CHT.
The installation of thermal relay, to avoid overheating and burn the braking resistor. RS-485 communication. Special communication adapter.
MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
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-D740-2.2K-CHT.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used MITSUBISHI FR-D740-2.2K-CHT. 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-D740-2.2K-CHT.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Power: 7.5kw.
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. 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 conversiion 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-D740-2.2K-CHT.
