The Rexroth VT-VSPA1-1-11 Proportional Amplifier is an analog electronic valve control board designed in a standard Eurocard format (100 x 160 mm) for industrial rack installation. The device functions by converting standard input command values into a regulated, clocked current output stage to drive a single solenoid. Equipped with differential inputs, a built-in ramp generator, and comprehensive safety sub-circuits, it actively stabilizes coil current variations caused by fluctuating operating voltages or solenoid temperature shifts to guarantee precise hydraulic pressure regulation.

² Supply Voltage: 24 VDC standard nominal input.

² Power Consumption: Maximum capacity of 50 VA.

² Maximum Solenoid Current: Regulated current output up to 1.8 A.

² Dither/Clock Frequencies: Clocked power output stage operating with standard factory frequencies at 100 Hz and 160 Hz.

² Operating Temperature: Designed for industrial environments, operating safely from 0°C to 50°C.

Proportional Pressure Valve Control:

Hydraulic Pressure Regulation:

Controlled Acceleration & Deceleration:

Serves as the primary driver for all direct and pilot-operated proportional pressure control valves that utilize a single actuating solenoid without LVDT feedback loops.

Deployed in heavy industrial machinery, hydraulic presses, and injection molding equipment to ensure highly linear, continuous force and torque adjustments.

Utilizing its built-in dual-ramp generators, it is used in hydraulic machinery systems to eliminate mechanical shock by smoothly easing valves open and closed.
