Rackable Loop Amplifier

Opus Technologies LD2.0 Rackable Loop Amplifier

POA: Call 0191 414 4241

The Opus Technologies LD2.0 is a next-generation magnetic perimeter Rackable Loop Amplifier, which can excel in many applications; be it a low diaphonic phased loop system, or ultra high coverage system, with a built-in 90° or 0° phase shift module (2 amplifiers).

Continuous output current, and all the necessary functionalities (AGC, MLC, etc.) ensure the seamless installation of rooms measuring up to 450m². A fault synthesis is also included, allowing control of the Loop & Amplifier. It’s important to note, that the information displayed on the front panel can be deported thanks to a dry contact.
