Product Description:
The EEA-PAM-568-A-32 power amplifier is designed for precise control of hydraulic proportional valves. This robust amplifier supports demanding industrial applications requiring high accuracy, stable performance and versatile signal adjustments.
This EEA-PAM-568-A-32 power amplifier supports up to 1.8 A solenoid current and features flexible gain adjustment per direction ranging from 2.5 % to 10 %/V. Its factory set gain is 10 %/V for balanced control. This amplifier’s deadband compensation is set at 10 % of the maximum spool stroke but can be adjusted up to 50 % from the center position for optimized spool response. The zero adjustment spans ± 25 % of the maximum spool stroke that accommodates calibration for various valve configurations. This power amplifier input current at a 0 V command signal is 1.4 A even under zero command conditions. This amplifier unit also supports multiple ramp signal types including ramp up, ramp down and flat output that enables customized operation for smooth control transitions.
This EEA-PAM-5**-A-32 power amplifiers series model offers a high output resistance of 10 kΩ and maintains a precise drive signal within deadband limits. Key output conditions include voltages greater than + 10 V, less than – 10 V and at 0 V with an acceptable ripple of ±2 V. The drive signal at null outputs supply voltage - 1.5 V and supports a maximum current of 50 mA. When active, the drive output maintains 0 V (± 2 V tolerance) to ensure accurate and stable null point control. The ramp active indicator (b12) and the drive signal zero indicator (b20) of this amplifier provide clear diagnostic feedback that enhances operational monitoring. This power amplifier’s combination of adaptable settings, strong output parameters and feedback indicators ensures high precision and reliability.
