Description

Belimo fail-safe damper actuators have a comprehensive torque offering from 2.5 Nm to 40 Nm with direct coupled, rotary or linear travel that can handle many HVAC applications. Fail-safe actuators use brushless DC motor technology controlled by an Application Specific Integrated Circuit (ASIC) to provide stall protection, lower power consumption, higher efficiency and smaller transformer sizing.
