VM20-C

The VM20-C from Bosch Rexroth Indramat is a precision Amp Drive in the VM Amplifier Drives series designed to provide reliable signal amplification in industrial and audio monitoring applications. With a frequency response of 20Hz – 20KHz and a sensitivity range of -43dB ~ 23dB, this unit ensures accurate reproduction of the full audible spectrum and flexible handling of varying input levels. As an Amp Drive, its primary function is to boost low-level signals into clear, powerful outputs suitable for integration into complex automation systems and professional audio setups.

Incorporating a 3.7V Li-ion battery with a 300mAh capacity, the VM20-C enables extended operation without frequent recharging, while a built-in low-cut filter at 75Hz effectively suppresses unwanted low-frequency noise and environmental hum. The device delivers a signal-to-noise ratio exceeding 75dB and a maximum SPL of over 105dB, providing exceptional signal clarity and dynamic range. Output is routed through a standard 3.5mm TRRS connector for straightforward interfacing with a broad range of equipment. The robust design and integrated protections underscore its suitability for harsh industrial environments.

Beyond core performance, the VM20-C offers seamless compatibility via its universal TRRS output form and meets necessary quality standards as indicated by its certification status. Its robust construction and one-year warranty ensure lasting durability and reduced maintenance downtime. The compact footprint and lightweight design simplify installation in both stationary racks and portable monitoring rigs. By combining high fidelity, efficiency, and rugged reliability, the VM20-C enhances signal integrity in demanding industrial automation and audio applications, delivering consistent performance where precise monitoring and control are paramount.
