Product Description

The Vickers EEA-PAM-591-A-10 belongs to the EEA-PAM-5-A-12 Power Amplifier series and is known for its reliability. It is used mostly in industrial applications as it is supplied with a +24 VDC nominal voltage and is equipped with a reverse polarity protection mechanism to prevent the equipment from being damaged by incorrect wiring. This amplifier has proportional, integral and derivative (PID) control that facilitates fine-tuning of the system. It also supports both ~10V voltage commands and current loop commands, making it compatible with a wide range of control systems for seamless integration. This amplifier has a +/-200 mA power output, which can be adjusted.

The output bias and dither of the EEA-PAM-591-A-10 are important features of this power amplifier. Another key feature is the ~12% electronic biasing, which allows users to fine-tune performance by adjusting the output. Also, it contains a specific amplitude-modulated constant frequency AC signal at 200Hz to reduce static friction as well as increase control accuracy. This feature is useful in hydraulic and servo systems as steady motion is crucial in such applications. Therefore, the output bias and the dither function work as two desirable components to improve the steadiness of the system and minimize output variations.

Another feature is the current limiter, which helps in the output adjustment of connected valves. This protects the amplifier from overpowering which can cause a breakdown of the hydraulic or electrical equipment. Thus, by using this current limiter, it is possible to increase the durability of the system and adjust the amplifier according to the working conditions. The current limiter adjustment is a feature that is used in improving the safety and efficiency of operations and is used in many industries.
