Power: 30kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function.
MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.4KW.
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-HC2-H30K
FR-HC2-H30K
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-HC2-H30K.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Power: 220kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
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 FR-HC2-H30K.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits.
Low noise.
No surge current.
Reduce motor loss (standard motor). 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%).
Starting with power frequency power supply, the starting current is 6~7 timess of the rated current, therefore, the impact on the mechanical and electrical FR-HC2-H30K.
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-HC2-H30K.
