Product Description:

The Bosch Rexroth VT 5011 S42 is an efficient valve controller for proportionally controlled throttle valves. This amplifier module offers exceptional performance in regulating fluid flow, making it suitable for valve regulation in demanding hydraulic systems. Its versatile design integrates a smoothing circuit, which is designed to reduce voltage fluctuations and provide a more stable output. This helps to maintain consistent performance in proportional valve control, minimizing sudden changes in flow or pressure. The amplifier also comes with a voltage stabilizer that compensates for any fluctuations in the input voltage, maintaining a steady output regardless of variations in the power supply. This helps to protect sensitive components from potential damage caused by voltage spikes or drops, ensuring the amplifier operates within optimal conditions.

The VT 5011 S42 features an integrated PID (Proportional-Integral-Derivative) regulator, which optimizes the control of throttle valves by continuously adjusting the output. This regulator helps to maintain precise control over the valve's position, ensuring that the desired output is reached quickly and remains stable over time. The amplifier also includes a Pulse Width Modulator (PWM) for controlling the output signal to proportional valves. This adjusts the duty cycle of the signal to regulate the amount of power delivered to the valve, allowing for fine-tuned control of valve positioning and throttle response.

This unit is designed to handle a maximum output current of 2.5 A for the solenoid, making it capable of driving solenoids with higher power requirements. It is equipped with a 3 A fuse wire, which provides essential overcurrent protection for the amplifier. In the event of a short circuit or an overload condition, the fuse will blow, protecting the system from potential damage.
