EEA-PAM-523-C-32

EEA-PAM-523-C-32 is a Vickers unit in the EEA-PAM Power Amplifiers series. It operates from a 24 VDC supply-voltage input and provides a 15 VDC control-supply output for compatible control circuitry. The bipolar command-source voltage is 10 V, while the command-source current is 10 mA, providing electrical command signals for amplifier control. Four command-voltage inputs allow the unit to receive multiple voltage-based control signals.

The bipolar current input is 20 mA and has an impedance of 100 Ω, allowing the amplifier to process a bidirectional current command. The polarity-select input has an impedance of 47 kΩ and is used to select the command polarity. Logic inputs draw a maximum current of 10 mA, which establishes the maximum load placed on connected logic controls.

The amplifier supports a 5 kΩ external command potentiometer for manual command adjustment. This external potentiometer requires a minimum power rating of 0.25 W. Four preset potentiometers, each with a value of 50 kΩ, provide adjustable preset command levels. Four ramp generators control the rate at which corresponding command signals increase or decrease.
