The Belimo LF24-SR Damper Actuator used for controlling the airflow in HVAC systems, which is essential for proper ventilation. It has spring return fail-safe mode to ensure its operation even when there is a power failure. It runs on a 24V power supply and has 35 in-lb torque, and is controlled by a 2-10 VDC analog signal for easy modulation. It is suitable for air handling units, VAV systems, and exhaust dampers to improve the performance of the system by providing proper air distribution.
The Belimo LF24-SR 24V;35;S/R;2-10Vdcprop is an advanced actuator designed for HVAC systems. This actuator operates on a 24-volt power supply and can withstand pressures of up to 35 pounds, suggesting powerful reliability and dependability. Its spring return (S/R) feature provides fail-safe operation by automatically returning to a predefined position in the event of a power outage or system failure. Furthermore, the actuator uses a 2-10Vdc proportional adjustment signal, which allows for precise and responsive adjustments to airflow or fluid circulation rates. The Belimo LF24-SR regulates the flow of air or fluids within these systems. It improves system performance and energy efficiency by precisely controlling the position of dampers or valves based on the control signal inputs. The Belimo LF24-SR is known for its dependability, which ensures consistent and trouble-free operation even in demanding environments. Its precise control features help to improve comfort and reduce energy consumption by maintaining optimal conditions within the HVAC system. The Belimo LF24-SR 24V;35;S/R;2-10Vdcprop is a dependable and efficient solution for achieving precise control and peak performance in HVAC systems.
Key Features for Belimo LF24-SR 24V;35;S/R;2-10Vdcprop
2-10Vdc Proportional Control: Precise positioning based on a 0-10 volt DC control signal allows for accurate control of airflow or fluid flow.
Closing Torque: 35 lb-ft (pound-feet)—high torque for a wide range of damper sizes and air pressures.
Spring Return (Fail-Safe): consequently returns to a closed position upon power loss. ensures system safety during emergencies.
Power supply: 24V DC; appropriate with standard building control systems.
Compact and lightweight design: fits easily into small spaces and clarifies installation.
Signs of a Faulty Belimo LF24-SR 24V;35;S/R;2-10Vdcprop:
Uneven Heating or Cooling: If different areas of your building have significant temperature variations despite balanced thermostat settings, it could indicate a faulty actuator failing to adjust dampers properly.
Poor Airflow: Restricted airflow from blocked ducts can be caused by a jammed actuator that's stuck in a closed position. Conversely, excessive airflow exceeding desired levels might occur if the actuator is stuck open.
No Response to Control Signals: If the actuator doesn't respond to commands from the building's control system, even when the signal voltage changes, it might be malfunctioning internally.
Unusual Noises: Grinding or screeching noises coming from the actuator during operation can signal internal wear or damage.
