Product Description:

The 20BA025FXW0X Amplifier is the product of Sanyo Denki and it is part of the BL Super Servo Amplifiers series. It is widely used in industrial automation applications to control and manage servo motor operations.

The 20BA025FXW0X amplifier has a high precision tuning module which helps in minimizing external electromagnetic interference and ensures stable signal processing. It comes with adjustable potentiometers which allows for manual fine tuning of the amplifier’s parameters, such as gain, offset or feedback control which is crucial for optimizing motor performance and stability. It also includes a large heat sink which suggests that the amplifier handles substantial electrical loads. It also features a DB Type connector which indicates that it supports external encoder feedback or external control signals which allows it to interface with controllers, motors or other automation systems. It is a robust and industrial grade built with a weight of only 7.4 kg. This module has a physical size of 45 cm x 16 cm x 20 cm which is important for installation considerations in control panels. With the inclusion of multiple ICs and microcontrollers it is featured with digital control features and real time processing capabilities which enhance its precision and dynamic response.

The 20BA025FXW0X amplifier includes connectors and ribbon cables which provide structured internal and external connectivity and ensures secure communication between different circuit sections and external components. This model has multiple terminal blocks labeled as R, S, T, U, V, W and E which suggests three phase power input and motor connections and means the amplifier is designed to drive three phase servo motors. Also, large capacitors and high power resistors are present in this model which indicates it is designed to handle significant current loads and ensures stable voltage.
