EEA-PAM-513-A-32 Product Description
The Vickers EEA-PAM-513-A-32 is a sophisticated power amplifier designed to enhance the performance of proportional control valves in a variety of industrial applications. This power amplifier is part of the renowned EEA-PAM-5 series and is engineered to provide precise control, ensuring efficient and reliable operation of hydraulic systems.
With dimensions of 40.3 x 191.44 x 128.4 mm, the EEA-PAM-513-A-32 is compact and designed for easy integration into existing systems. It features multiple voltage inputs, including one inverting input, and a current input for 0-20 mA, allowing for flexible connectivity with different control signals.
The unit is equipped with adjustments for setting the zero point or deadband compensation, as well as gain adjustments, enabling fine-tuning to match the specific requirements of the proportional valve it controls. The ramp function generator can be switched on or off using the "ramp enable" control, providing additional versatility in managing the rates of increase and decrease of the output.
Front-panel monitor points allow for the measurement of the conditioned command signal and, depending on the valve configuration, either the spool position LVDT signal or the solenoid current. The "conditioned command signal" is the input signal modified according to the settings of set zero point or deadband compensation, gain, and ramp functions.
The EEA-PAM-513-A-32 is designed with user-friendliness in mind, featuring a front panel with all necessary adjustments, LEDs, and monitor points for straightforward operation and monitoring. It also includes electronic overload protection with automatic reset, pulse width modulation for high efficiency, and the capability to be equipped with plug-in modules for special functions.
This power amplifier operates with a 24V DC power supply and accepts either current or voltage input signals, adhering to standard input and output signal requirements. It is suitable for a wide range of industrial environments and applications where precise hydraulic control is essential.
