Electronic damper actuators with emergency function
Electronic damper actuators with emergency function
Damper actuators with electronic fail-safe functions are designed to provide enhanced reliability and control in HVAC systems, fan coil units, and laboratory applications. These advanced actuators ensure precise damper positioning, even in the event of power interruptions, making them ideal for critical airflow and safety applications.
One of the key features of these actuators is the Electronic Return (ER) function, which can handle short voltage interruptions of up to 4 seconds without affecting the actuator's position. If a longer power interruption occurs, the actuator will automatically move the damper to a predefined emergency position (EPS). This ensures that ventilation, airflow regulation, or laboratory conditions remain stable, preventing system disruptions or safety risks.
These electronically controlled fail-safe actuators offer superior protection against power fluctuations, ensuring continuous and fail-safe operation. Their intelligent design and precise movement make them an essential component for modern, automated HVAC and laboratory systems.

Electronic fail-safe damper actuators
The NECA and NECM series electronic fail-safe damper actuators are specifically designed to provide extended functionalities in HVAC systems, fan coil units, and laboratory applications. These actuators offer reliable airflow control, ensuring smooth operation and enhanced safety, even in the event of power interruptions.
During normal operation, the actuator precisely motorizes the damper to the required position. However, if the power supply is interrupted, the built-in Electronic Return (ER) function allows the actuator to handle short voltage drops of up to 4 seconds without affecting damper positioning. If the power outage lasts longer, the actuator will automatically move the damper to a predefined emergency position (EPS), maintaining system stability and preventing unwanted disruptions.
Features:
- Fail-safe function: Ensures reliable operation by moving to a predefined emergency position (EPS) during power failure.
- Electronic Return (ER): Can handle short power interruptions (up to 4 seconds) without affecting damper control.
- Torque options: 2 – 20 Nm, making it adaptable for different damper sizes.
- Power supply flexibility: 230 VAC or 24 VAC/VDC, ensuring compatibility with various systems.
- Running time: 35 – 65 seconds, allowing smooth and precise damper movement.
- Auxiliary switches (optional): Available with 1 or 2 adjustable SPDT auxiliary switches for enhanced control and monitoring.
The NECA and NECM actuators are engineered for high performance, durability, and energy efficiency, making them a perfect choice for demanding HVAC and laboratory environments. Their fail-safe technology ensures that airflow remains controlled and secure, even in unpredictable conditions.

Electronic fail-safe damper actuator with modbus
The MECA series electronic fail-safe damper actuators are specifically engineered to provide advanced functionality and safety in HVAC systems, fan coil units, and laboratory applications. These actuators offer precise airflow regulation, ensuring system stability even in power failure scenarios, making them an ideal choice for critical ventilation and climate control systems.
During normal operation, the actuator accurately motorizes the damper to the required position. In the event of a power supply interruption, the Electronic Return (ER) function enables the actuator to withstand short voltage drops of up to 4 seconds without affecting the damper’s position. If the power failure persists, the actuator will automatically move the damper or valve to a predefined emergency position (EPS), ensuring the system remains protected and operational.
Features:
- Fail-safe function (EPS): Automatically moves to a predefined position in case of power failure.
- Electronic Return (ER): Handles short power interruptions (up to 4 seconds) without altering damper position.
- Modbus communication: Seamless integration with Building Management Systems (BMS) for remote monitoring and control.
- Torque options: 5 – 20 Nm, adaptable for various damper sizes.
- Power supply: 24 VAC/VDC, ensuring flexibility across different HVAC set
- Running time: 35 – 70 seconds, allowing smooth and precise damper movement.
