EEA-PAM-581-A-33

EEA-PAM-581-A-33 is a Vickers power amplifier in the EEA-PAM Power Amplifiers series. The card measures 175.24 mm in height, 122.4 mm in width, and 40.3 mm in depth, which establishes the installation space required for the unit. It operates at a nominal supply voltage of 24 V DC and has a 50 W power-supply rating for powering the amplifier circuitry.

The control supply provides +15 V and -15 V outputs for connected control circuits, with a maximum control supply current of 50 mA. The unit also provides +10 V and -10 V reference outputs for command and reference signals. These reference outputs support a maximum current of 5 mA.

The voltage input has an impedance of 47 kΩ, limiting the load placed on a connected voltage signal source. The current input impedance is 100 Ω for receiving current-based command signals. The drive and ramp enable input has an impedance of 22 kΩ, while the monitor output has an impedance of 10 kΩ for connection to monitoring equipment. Overload detection uses automatic reset, allowing the amplifier to reset its overload state without a manual reset operation after the fault condition clears.
