Electronic damper actuators with emergency function
Electronic damper actuators with emergency function
Damper actuators with electronic emergency functions are designed for extended functionalities in HVAC systems fan coil and laboratory applications. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS).
Electronic fail-safe damper actuators
NECA and NECM series electronic fail-safe damper actuators are designed for extended functionalities in HVAC systems fan coil and laboratory applications. During normal operation, the actuator motorizes the damper. When the power supply is off, the actuator is back to its original position. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS).
Features
- Torque 2 – 20 Nm
- Power supply 230 VAC or 24 VAC / VDC
- Running time 35 – 65 sec
- Auxiliary switches optional, 1 or 2 adjustable SPDT auxiliary switches

Electronic fail-safe damper actuator with modbus
MECA series electronic fail-safe damper actuators are designed for extended functionalities in HVAC systems fan coil and laboratory applications. During normal operation, the actuator motorizes the damper. When the power supply is off the actuator is back to its original position. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS). These actuators have Modbus communication and could be used for BMS systems.
Features
- Torque 5 – 20 Nm
- Power supply 24 VAC / VDC
- Running time 35 – 70 sec
- Auxiliary switches optional, 1 or 2 adjustable SPDT auxiliary switches
