Product Description:

EEA-PAM-568-A-33 is a small, robust power amplifier by Vickers and belongs to the EEA-PAM series. This amplifier weighs only 0.4 kg and is designed to command hydraulic valves and single-action actuators in industrial automation systems. It runs on a nominal supply voltage of 24 V DC but can be used reliably with an operating range of 20 V to 40V DC, making it flexible enough to be used in different types of electrical applications. It consumes 50W of power, which makes it relatively power-efficient and can run complex control tasks.

The amplifier is designed to work with a wide range of input signals, including a current range of ~20?mA and a voltage range of ~10?V. It features a high input impedance of 47 k? at a current of 100 A, allowing it to interface easily with a wide range of control devices. Another key feature of the amplifier is its precise output signal performance, which is characterized by parameters such as ramp time ranging from 50 ms to 5 s, deadband compensation (up to 50% of the maximum spool stroke), and adjustable gain from 2.5% to 10% per volt, with a factory setting of 10 %/ V. These options are used to precisely control solenoid valves with up to 3.2A of output current.

The EEA-PAM-568-A-33 is a power amplifier that boosts limited electrical input signals (current or voltage) to levels high enough to control larger devices, such as hydraulic solenoids. A controller or PLC normally supplies the input signal. The amplifier improves the input signals by making them stronger. The amplifier processes the signal using ramp and gain controls to fine-tune its performance before delivering it as the output.
