SF Series Spring Return with Emergency Function

New SF Series spring return actuators with emergency function for adjusting air dampers in ventilation and air conditioning systems in buildings. These replace the current AF series.,The motor moves the damper to its normal operating position against spring tension with a powerful turning and holding torque of 20 Nm. The spring will then return the damper to its safe position should the power supply be interrupted.

Brushless motors ensure a service life of 60000 operations
Can be installed with pre-tensioned spring
Manual winding and integral position fixing options allow installation and functional monitoring without electrical connection
Adjustable U-clamp accepts round or square shafts; round sizes 10 to 25.4 mm and square shafts 10 to 18 mm across flats, and 14 to 25.4 mm diagonal
Direction selector
IP54 rated
150 second motor run time
1 metre pre-wired cable
Stock nos. 712-2668 & 712-2652 feature an integrated 2xSPDT 6 (3)A 250Vac auxiliary switch

Belimo Modulating Damper Actuator
