Product Description:

The Vickers EEA-PAM-561-C-31 Power Amplifier is designed for controlling the proportional directional and flow control valves, for instance, Vickers KFDG5V. One of its important characteristics is its high flexibility. The amplifier comes with two installation methods, which include panel mounting and DIN rail mounting to support different system layouts and installations. Din rail mounting is most suitable for standardized and compact mountings, whereas panel mountings provide a more fixed or specific mounting. These mounting options enable users to connect the amplifier with other systems with ease, thus ensuring quick and easy installation.

The amplifier also has built-in LED lights that make it easy for one to determine the working status of the amplifier. These LED lights include green illumination, red indication and yellow indication lights, which are useful to determine the condition of the system. When the green light is on, it means that the system is in the proper working condition without defects, while the yellow light means a minor problem with the system. The red light implies an overload or a fault in the system, and it indicates that the user needs to take action immediately. These features facilitate quick identification to help resolve problems, ensuring low downtime and proper running of the system. Besides the LED indicators, the amplifier has test points for quick diagnostics in case of a problem.

Some of the key characteristics of EEA-PAM-561-C-31 amplifiers include deadband compensation, gain setting and ramp function generation for optimal valve control. It also uses LVDT feedback and has overload and reverse polarity protection capabilities to guarantee safe operation. In general, this power amplifier is perfect for users who want to improve the hydraulic control systems of their machines.
