EEA-PAM-535-D-32

EEA-PAM-535-D-32 is a Vickers power amplifier in the EEA-PAM Power Amplifiers series. It accepts a command voltage range of ±10 V or a command current range of ±20 mA for setting the control demand. The voltage input has an impedance of 47 kΩ, while the current input has an impedance of 100 Ω to provide the appropriate electrical load for each command signal type. A +15 V control supply output is available to power compatible control circuitry.

The feed-forward input operates over ±10 V and has an impedance of 6 kΩ, allowing an external signal to adjust the command response. The ramp input also accepts ±10 V and has a 10 kΩ impedance for controlling gradual signal changes. Its sensor voltage input impedance is 1 MΩ, which minimizes loading on the connected sensor signal. The monitor point provides a ±10 V range with a 10 kΩ impedance for observing amplifier operation.

Positive and negative reference outputs provide +10 V at 5 mA and −10 V at 5 mA, respectively, for external reference or command circuits. The alarm output supports a maximum current of 50 mA and has an output resistance of 50 Ω, providing an electrical indication for connection to compatible alarm-monitoring equipment.
