Vickers EHH-AMP-702 Series Plug-in Proportional Amplifiers

Product Overview:

The Vickers EHH-AMP-702 series is a highly integrated electronic proportional amplifier housed within a standard DIN 43650 plug. Specifically designed to drive proportional solenoids without displacement transducers, this amplifier accurately converts analog control signals (such as 0-10V or 4-20mA) into a regulated proportional current. Its compact “plug-in” design eliminates the need for expensive cabinet space and significantly reduces wiring complexity in the field. Whether used for pressure regulation or flow control, the 702 series delivers exceptional linearity and dynamic response.

Featured models: EHH-AMP-702-D-20 and EHH-AMP-702-K-20.

Key Technical Advantages:

• All-in-One Integration: Mounts directly onto the proportional solenoid, requiring zero rail space in the electrical cabinet and simplifying hydraulic system layouts.

• Precision Adjustment: Features onboard multi-turn potentiometers for field calibration of Gain, Deadband (Offset), and Ramp Times.

• Extreme Environmental Durability: The rugged plastic housing and encapsulated electronics provide excellent vibration resistance and IP65 protection for harsh industrial environments.

• PWM Drive Technology: Utilizes high-frequency Pulse Width Modulation to minimize solenoid power consumption and heat, while optimizing the hysteresis characteristics of the valve.
