Frequently Asked Questions (FAQ)
Q1. What type of proportional valve is the VT-VRRA 1-537-20/V0 designed to control?
A1. It is designed for standard proportional directional and pressure control valves without electrical position feedback (no LVDT).
Q2. Can I adjust the acceleration and deceleration behavior of my hydraulic system?
A2. Yes. The amplifier includes independent potentiometers for up-ramp (acceleration) and down-ramp (deceleration), enabling precise motion-profile tuning.
Q3. How does the amplifier maintain reliable performance in electrically noisy industrial environments?
A3. It uses robust internal filtering and a regulated power supply to deliver clean, stable signals to the solenoids, effectively rejecting electrical interference.
Q4. What is the maximum output current of this amplifier?
A4. The amplifier can deliver up to 800 mA per solenoid, suitable for driving a wide range of proportional valve sizes.
