NAFA SERIESSPRING RETURN DAMPER ACTUATOR2 Point Spring Return Control3 Nm Nenutec Asia Pacific Pte. Ltd.

NAFA SERIESSPRING RETURN DAMPER ACTUATOR2 Point Spring Return Control3 NmNAFA.03 (S) SERIESNAFA series Spring Return actuators are developed for general air damper application, rotaryvalve and other devices which require a fail-safe function. During normal operation, the actuatormotorized the device. In the event of power outage, the actuator springs back to its original position.PRODUCT FEATURE Torque 3 Nm Damper size 0.6 m² Power supply AC/DC 24V and AC 230 V Shaft dimensions - Ø 10.16 mm / 7.11 mm Minimum Shaft Length 40 mm Adjustable angle of rotation Selectable direction of rotation of reversing actuator Actuator with 1 m cable connection Optional 1 Fixed and 1 Adjustable SPDTauxiliary switchesMODEL SELECTION TABLEMODEL / TYPE TORQUENAFA 1-033 NmNAFA 1-03S3 NmNAFA 2-033 NmNAFA 2-03S3 NmPOWER SUPPLYRUNNING TIME25.55 sec(Spring Back 20 sec)25.55 secAC/DC 24 V 10%(Spring Back 20 sec)25.55 secAC 230 V 10%(Spring Back 20 sec)25.55 secAC 230 V 10%(Spring Back 20 sec)AC/DC 24 V 10% Nenutec Asia Pacific Pte.
