VT 2000 S47/2
The VT 2000 S47/2 proportional amplifier from Bosch Rexroth Indramat, part of the VT 2000 Proportional Amplifiers series, is designed for precise control of proportional hydraulic valves in industrial automation. Its primary function is to regulate solenoid coil activation with an input voltage range of 0 to ±16V DC, delivering a current output of up to 1000mA (1A). The front-panel ramp control allows adjustable ramp-up and ramp-down rates, ensuring smooth valve actuation and reducing hydraulic shock.
This amplifier operates on a nominal voltage of 220V at 50Hz with an efficiency of 85% and a power factor of 0.95. It incorporates a gold-plated edge connector for robust modular integration and screw-terminal or multi-pin interfaces for power and signal wiring. Internal components include operational amplifiers and power transistors for signal processing and solenoid driving, alongside flyback diodes and a +200μF/40V electrolytic capacitor for surge protection and voltage stabilization.
Built for reliability in demanding environments, the VT 2000 S47/2 features DIN rail compatible mounting and rugged protection components to withstand voltage spikes and electrical noise. The inclusion of inductors and transformers ensures consistent signal conditioning and galvanic separation, enhancing durability and long-term stability. With a maximum current rating of 5A and a proven track record in industrial automation, this amplifier delivers repeatable performance, reduces maintenance downtime, and optimizes hydraulic valve precision in high-performance applications.
