Product Description:
Vickers is a leading manufacturer of hydraulic components and systems for industrial automation and mobile applications. Their product range includes valves, pumps, actuators, and power amplifiers designed for high precision and performance control.
The EEA-PAM-553-D-32 power amplifier from Vickers provides robust control for hydraulic proportional valves by enhancing system efficiency and response. It operates with a control output supply of + 15 V for LVDTs and features reference voltage outputs of ~ 10 V at 5 mA. Command inputs are supported through direct-voltage pins with an input impedance of 47 k?, accepting a voltage range of ~ 10 V. It also accommodates current input signals with a ~ 20 mA current range and 100 ? impedance for accurate control adjustments. The amplifier includes multiple inputs for feed-forward, sensors, and a ramp generator. Feed-forward input impedance is 6 k?, with a voltage range of ~ 10 V, while the ramp generator input impedance is 10 k?. Sensor inputs support both voltage and current signals, with a voltage range of 0 to ~ 10 V and current inputs ranging from 4 degrees CE" 20 mA. The PID controller enable voltage is between 17 and 40 V when enabled, or 0 to 3.5V when disabled, consuming less than 10 mA.
The EEA-PAM-553-D-32 power amplifier also includes configurable potentiometers for adjusting feed-forward, P-gain, I-gain, and D-gain ranges. This provides flexible control settings for different hydraulic systems. The model's Output signals are designed for short-circuit protection, with load impedance specifications for the PID-controller output, error signal, and feedback signal set to 10 k?. Additional features include digital outputs for sensor failure and feedback conditions, alarm outputs, and indicators for ramp activity and drive signal zero status.
