Product Description
The Belimo LMCB24-SR is a high-performance damper actuator designed for HVAC systems, providing efficient control for air flow regulation. Engineered for direct mounting to damper shafts ranging from 0.25 inches to 0.625 inches in diameter, this model offers precise modulation of dampers through a 2 to 10 VDC signal or, with additional components, a 4 to 20 mA signal. Its robust construction and sensorless brushless DC motor ensure reliable and extended operation without routine maintenance requirements.
- Non-spring return mechanism with 45 in-lb torque for robust operation.
- Electronic protection against overload and position feedback for system integration.
- Manual override button and visible position indicator for ease of operation.
Product Highlights
This actuator features a sensorless brushless DC motor controlled by an ASIC to monitor actuator rotation, increasing reliability and performance. The integral digital rotation sensing prevents damage during stall conditions, and power consumption is optimized in holding mode to reduce operational costs.
