Electronic damper actuators with emergency function

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.
• Auxiliary switches (optional): Available with 1 or 2 adjustable SPDT auxiliary switches for enhanced control and automation.

The MECA actuators are designed to meet the growing demand for energy-efficient, automated, and fail-safe damper control. With Modbus connectivity, they provide real-time diagnostics, allowing facility managers to optimize system performance and reduce energy consumption. Their durability and intelligent control make them perfect for modern HVAC infrastructures, laboratories, and industrial environments.
