MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 22KW.
Inverter general area of domestic enterprises to occupy more than 80% of the market share,
Production of frequency converter, motor soft starter and other industrial automation control of the manufacturers, the use of heavy-duty design products,
Overload capacity, with super large start and running capacity, improve the automatic detection, protection and control performance,
Products have been widely used in metallurgy, mining, paper, chemicals, building materials, machinery, electricity, and construction systems and other industrial transmission areas.
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1.5KW.
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%) FR-A720-22K
FR-A720-22K
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-A720-22K. Power: 280kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter FR-A720-22K.
Three types of discharge resistors are available.
Please select according to the required braking torque. "MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
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" (inverter) FR-A720-22K.
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-A720-22K.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "
