VT11073-11
The Bosch Rexroth Indramat VT11073-11 belongs to the advanced VT Servo Amplifiers series and is engineered for precise proportional directional valve closed-loop control. This frequency inverter drive operates on a 230 V input voltage and leverages a standard 24 VDC control voltage for seamless integration with industrial automation systems. With a rated load capacity of 2 HP, the VT11073-11 provides robust power handling for demanding valve actuation tasks, ensuring reliable performance in three-phase applications.
Featuring an integrated DC/DC Converter and a dedicated U/I Converter, the VT11073-11 maintains stable operation across varying supply voltage conditions while offering short-circuit protection at 0 V. The amplifier supports a ±10 V differential signal input, enhancing the precision of valve positioning. A built-in Dither Signal Generator minimizes sticking and improves fluid responsiveness, and reverse polarity protection safeguards the electronics against incorrect wiring. The unit can drive currents up to 20 mA, making it ideal for dynamic control of hydraulic and pneumatic valves in closed-loop setups.
Designed for effortless installation, the VT11073-11 is compliant with EN 60715 hat rail mounting standards and includes a built-in LED indication for real-time monitoring of the internal power supply voltage. Its three-phase architecture and robust protection features ensure compatibility with a wide range of industrial automation platforms while delivering superior durability and operational efficiency. By integrating advanced signal conditioning, protective circuitry, and intuitive diagnostics, this servo amplifier enhances system reliability and precision, driving productivity gains in complex manufacturing and process control environments.
