Voltage level: three phase 400V.
Applicable motor capacity: 500kw.
Substrate coating: have.
Built in DC reactor.
The operating frequency of the fixed alternating current is converted to DC power.
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 37KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI FR-CC2-H500K-60.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit
FR-CC2-H500K-60
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI FR-CC2-H500K-60. Length: 5 meters.
Operation panel or parameter unit connection line. Superior high efficiency IPM motor.
Output power: 5.5kw.
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 MITSUBISHI FR-CC2-H500K-60.
1 inverters can not connect multiple IPM motors at the same time. Power: 37kw.
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-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity MITSUBISHI Three phase 400V grade frequency converter.
At the same time the installation options in the use of 75kW and above motor MITSUBISHI Three phase 400V grade frequency converter. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V MITSUBISHI Three phase 400V grade frequency converter.
Frequency converter capacity: 18.5KW.
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%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated ccurrent, therefore, the impact on the mechanical and electrical FR-CC2-H500K-60.
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 MITSUBISHI FR-CC2-H500K-60.
