Faber‑com VPP2 (“PVPP2”) Electronic Regulator / Potentiometer

Overview

The VPP2 (often sold as PVPP2) is a panel-mounted electronic regulator designed for single‑solenoid proportional valves in open-loop control systems. It integrates a potentiometer on the board for direct manual adjustment of the output current.

Key Specifications

Features & Functional Description

• The VPP2 includes a built-in potentiometer for manual current setting, eliminating the need for external control wiring for that function.
• Backend trimming potentiometers (on the circuit board) allow calibration of I_min, I_max, ramp up, ramp down, and PWM frequency to match different valve characteristics.
• The regulator uses PWM control of the solenoid, enabling efficient energy delivery and fine current control.
• A test point is typically provided (1 V corresponds to 1 A of output) to monitor output current.
• The electronics are encapsulated in epoxy resin for durability and environmental protection.
• A label with a 0–10 scale is provided with the unit to align with the potentiometer knob for easier reference during adjustment.

Applications

The VPP2 is ideally deployed in hydraulic systems or electro-hydraulic controls where a single proportional solenoid valve must be controlled by a manual (operator) input via the potentiometer. Common use cases include:

• Mobile machinery (e.g. boom or tilt control)
• Industrial hydraulic machines
• Retrofit or control panels where variable manual adjustment is needed

Ordering Considerations & Variants

• There are variants with a potentiometer rated for IP67 protection for more demanding environments.
• The product is sometimes referenced as “panel version” in Faber‑com catalogs under the designation VPP2.
• If integrating into a system, ensure your solenoid coil current, supply voltage, and thermal conditions are compatible with VPP2’s limits.
