"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.
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. "
Power: 3.7kw.
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-F740-15K-CHT.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table
FR-F740-15K-CHT
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
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-F740-15K-CHT.
The installation of thermal relay, to avoid overheating and burn the braking resistor. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 45kw.
SLD converter rated current: 233A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel FR-F740-15K-CHT. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. Power: 90kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave FR-F740-15K-CHT.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operationnal characteristics of the sine wave power driver, can provide the following benefits FR-F740-15K-CHT.
Low noise.
No surge current.
Reduce motor loss (standard motor).
