VT-PK1-30 by Bosch Rexroth Indramat

The VT-PK1-30 proportional amplifier from Bosch Rexroth Indramat is a high-performance module in the VT-SSPA Plugin Proportional Amplifiers family designed for precise control in industrial motion systems. With a nominal current factory setting of 1.6 A and a minimum coil inductance of 15 mH, it delivers stable output under varying load conditions. This device functions as a compact control unit that regulates coil currents to achieve smooth, accurate actuator movement.

The VT-PK1-30 offers extensive adjustability, featuring a biasing current range of 0...300 mA and a maximum current setting up to 1.7 A (model dependent). It supports a clock frequency at Imax of 340 Hz, ensuring rapid response for dynamic motion profiles. The command value input spans 0...10 V, enabling integration with standard control signals, while the ramp time can be tuned between 100 ms to 5 s for tailored acceleration and deceleration curves. Connectivity is straightforward via four screw terminals (cable diameter 4.5 to 11 mm) and a 4-pin M12 component connector, M12x1, simplifying installation and maintenance.

Built to withstand harsh environments, the VT-PK1-30 operates reliably from –25 °C to +70 °C and complies with IP65 to EN 60529 standards for dust and water ingress protection. Weighing only 0.125 kg, it occupies minimal cabinet space and contributes to efficient system design. Its robust construction and precise current control enhance system uptime and motion accuracy, making it an ideal choice for industrial automation applications that demand durability, efficiency, and seamless integration.
