Product Description:
The VT13477-22/1 Amplifier card by Bosch Rexroth Indramat is designed for controlling servo valves without LVDT feedback, ensuring precise performance in closed-loop applications. The amplifier card variant comes with a power supply current of less than 200 mA and an internal control voltage range of 14V to ±10V. The card integrates high-quality components that contribute to its reliability and efficiency in industrial automation.
The VT13477-22/1 amplifier card features multiple electrolytic capacitors, including a central blue capacitor that ensures power stability and energy storage. Inductors and transformers are present near the center of the amplifier board, supporting DC-DC conversion and current regulation. A small black integrated circuit near the upper right corner serves as a microcontroller that manages power and signal processing. A secondary square IC adjacent to the microcontroller likely functions as a power management IC for voltage regulation. The amplifier outputs ±60 mA or ±100 mA, ensuring steady operation from 0 to 50°C (34 to 122°F). Top right on the amplifier card are blue voltage input and output connectors. Jumper pins enable voltage level modifications. To stabilize output voltage, the amplifier card supports moderate current levels, possibly 1A to 10A.
The operating settings can be adjusted using several jumper pins on the VT13477-22/1 amplifier card. The switching frequency is optimized for power conversion efficiency, ranging from about 100 kHz to 1 MHz. Because of its versatile design, the amplifier card can accept input voltages ranging from 5V to 40V, making it suitable for use with a variety of power sources. Inductors and transformers covered with heat sink material are used for thermal management, which guarantees constant performance regardless of the load. For servo applications, this amplifier card ensures constant performance by providing stable and accurate control.
