FR-F740-0.75K-CHT MITSUBISHI 3 phase 400V converter
Brand:
MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740-0.75K-CHT
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.75KW.
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.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
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-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 FR-F740-0 FR-F740-0.75K-CHT75K-CHT MITSUBISHI.
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 FR-F740-0.75K-CHT MITSUBISHI.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Superior high efficiency IPM motor.
Output power: 0.75kw.
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 FR-F740-0.75K-CHT MITSUBISHI.
1 inverters can not connect multiple IPM motors at the same time. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 15.0kw.
SLD converter rated current: 31.0A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. Power: 0.4kw.
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.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistoor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-F740-0.75K-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 thhe short circuit chip, in addition to connecting the DC reactor FR-F740-0.75K-CHT.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
