Product Description

Need a valve for an application that requires a single adjustable ramp setting for both deceleration and acceleration? The Vickers EEA-PAM-571-A-14 Power Amplifiers Card mentioned is designed for use with different valve types. For example, the EEA-PAM-561-A-14 cards which can be used with KDG5V-5, 3* and KDG5V-7, 1* valve types. The EEA-PAM-568-A-14 is for use with KDG5V-8, 1* series valve types.

Enabled by a 24-volt logic signal, the amplifier requires the power supply to provide 24V DC. The basic amplifier was created for 2 stage proportional valves such as the Vickers brand, type KFDG5V-5/7/8, 2-stage proportional valves. There are a number of different types of analog command input signals; these include inverting or differential voltages, non-inverting voltages, and non-inverting current.Suitable wiring can allow for the selective disabling of the ramp which is normally enabled. This selective disabling can be done with an external switch with the right connecting wiring.

On the front panel of the amplifier, you will find LED’s which show the power status, the control supply status and the output status. You will be able to adjust ramp, adjust dead band compensation and also adjust dead band gain with the use of potentiometers which are mounted on the front of the panel. The basic valve amplifier features voltage and current command signals. With just 1 ramp for both acceleration and deceleration and utilizing a 24V DC power supply with pulse width modulated coil drives, it gets the job done. The 14 design offers a wider range of voltage supply and also provides a higher ripple tolerance while providing protection from a low supply of voltage. With additional monitoring points on the edge connector and ramp settings that are unaffected by adjustments in gain this amplifier really delivers. Along with all those features you get dead band compensation thanks to constant trigger voltage.
