MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
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%) FR-F740-S355K-CHT PDF FR-F740-S355K-CHT
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.
The inverter drive can be smoothly start (start time longer).
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 FR-F740-S355K-CHT PDF. Power supply: 110mA DC5V (PLC internal power supply), 90mA DC24V (external power supply).
Analog input points: 4 points.
Voltage input: DC-10~10V.
Current input: DC-20~20mA, 4~20mA.
Weight: 0.2kg.
Dimensions: 55 x 90 x 87 FR-F740-S355K-CHT PDF.
Voltage input and current input of 4 channels can be carried out,
Each channel can be specified as a current input or voltage input.
Built in digital filter function and peak hold function, etc.,
Achieved a high speed of 500 AD S/ch conversion.
FX3U-4AD can connect FX3GA/FX3G, FX3GE, FX3U series.
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-IPS-5V. "MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 2.2KW.
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" (inveerter) FR-F740-S355K-CHT datasheet.
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 invertter FR-F740-S355K-CHT datasheet.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "
