Product Description:
The model EEA-PAM-525-D-32 is a versatile power amplifier designed by Vickers to enhance the performance and reliability of control systems. This model offers efficient signal management and is engineered for precision in demanding industrial automation applications.
This EEA-PAM-525-D-32 power amplifier supports PID control that enables enhanced system stability through precise feedback regulation. The PID controller is activated at an input voltage range between 17 V and 40 V and deactivates when the voltage is between 0 V and 3.5 V. This unit is optimized for safe operation with a load current limit of ≤ 10 mA for analog controls. This model’s digital output channels are robust that allows a short circuit safe load current of ≤ 100 mA at pins d18 and d10. This amplifier’s sensor failure threshold is set below 3 V to ensure reliable detection of malfunctions. Feedback signal discrepancies compared to the demanded signal are promptly flagged when the feedback voltage drops below 3 V. This power amplifier is compatible with the K*G4V-3 proportional valve. Its design includes provisions for LVDT feedback that ensures precise spool position control in closed loop applications. The amplifier's power drive utilizes Pulse Width Modulation (PWM) and is short circuit protected.
Temperature drift of this EEA-PAM-5**-D-32 power amplifiers series module is minimal. It maintains less than 1 mV/°C over an operating temperature range of 0 to 50 °C. The device also features a ramp function generator with quadrant detection that allows for separate adjustments of acceleration and deceleration which can be enabled or disabled as needed. Front panel LEDs of this model provide status indications including supply voltage presence, control voltage status, solenoid output status and sensor failure alerts.
