LD3.0
Description
The Opus Technologies LD3.0 is next-generation perimerter magnetic loop amplifier. Continuous 10Arms output current capable and all necessary functionalities (AGC, MLC, etc) ensure rooms installation of 1000m².
The amplifier incorporates a fault synthesis that controls continuously the loop and the amplifier. The information is displayed on the front panel and can be deported thanks to a dry contact.
The LD3.0 can also bo used in a low diaphonic phased loop system or an ultra high coverage system with a built-in 90° or 0° phase shift module (2 amplifiers). Solution used for the equipment of large rooms or adjoining rooms (hairpin systems).
The LD3.0 proven technology and quality of manufacturing allow us to offer a 5 years warranty.
