Proportional distributors with built-in electronics

On-Board Electronics (OBE) is the direct and best way to compensate for the non-linear behavior of the switchboard. The position sensor and electronics on the switchgear body complement the control circuit directly on the power system member. Mechanical tolerances, friction, hysteresis and wear do no longer cause disturbances in the accuracy of the appliance's movement. With modern machine monitoring, the sensor information can also be sent to the machine's control system.

Benefits of deploying proportional technology

Efficiency, speed, accuracy, low hysteresis, repeatability, and the ability to change management are the key benefits of implementing proportional technology in hydraulic applications. ARGO-HYTOS switchboards, combined with advanced electronics, are able to meet the demands placed on a large number of stationary and mobile applications.
ARGO-HYTOS develops and manufactures proportional switchboards that enable customers to benefit fully from the benefits of proportional technology.
The new PRM9-06 and PRM9-10 cabinets with advanced electronics and mechanical components and together with rugged design make this possible.
