2LP25 is the most commonly used frequency converter in modern society. It is mainly used for controlling the starting speed and speed of AC asynchronous motors. It has become an important part of energy conservation and stable operation of electromechanical equipment.

2LP25 is a Frequency Converter manufactured by GEV, a global leader in power transmission products. It uses a single-phase or three-phase AC power supply. The voltage is normally between 200V and 480V; while the output power is between 0.4kW, 0.75kW, 1.5kW, 2.2kW, 4kW, 5.5kW, 7.5kW, 11kW or 15kW. It is used for controlling the speed and starting torque of AC asynchronous motors.

The application field of 2LP25 is quite wide. It is mainly used in industrial processes such as paper mills, textile mills, pumps, printing machines, food production machines, conveyor lines, escalators, lifts, etc. It also can be used in other machinery such as medical equipment, precision tools, centrifuges, fans, compressors, etc. In addition, it is widely used in medical and agricultural equipment.

The working principle of 2LP25 is relatively simple. It uses a digital frequency conversion technology coined as “digital adjustable frequency conversion”. It converts the mains AC voltage to DC voltage and then converts it back to AC voltage at a different frequency. This process is achieved through the pulse width modulation of semiconductor devices. The frequency can be adjusted from 0.45HZ to the rated frequency. This allows the users to tailor the motor speed to the most optimal level.

Once the desired frequency is set, the 2LP25 can also be used for controlling the motor acceleration or deceleration process. It can use the PWM signal or analogue signal to adjust the acceleration and deceleration time for the motor. This helps to reduce the mechanical force on the motor. And the PLC or microprocessor in the motor control system can be used for controlling the sequence of the action.

Overall, 2LP25 is a very versatile frequency converter which can be used for different AC asynchronous motors. Its ability to adjust the speed and acceleration makes it a suitable choice for various applications. With the help of PLC and CPU, it brings a higher degree of automation to the entire process and saves a lot of energy. With its wide range of application fields, it has become a popular choice for many industries.
