Product Details
Belimo Damper Actuator
The Belimo Sf series damper actuator has an open/close control type. It is a spring return actuators with an emergency function for adjusting air dampers in ventilation and air conditioning systems in buildings. It has an adjustable U-clamp, which accepts round or square shafts. This actuator can be installed with a pre-tensioned spring. This product is controlled with a standard signal of DC 0V to 10V and moves the damper to the operating position. This actuator is overload proof, requires no limit switches. It requires AC supply voltage between 19.2VAC and 264VAC and DC supply voltage between 21.6VDC and 137.5VDC.
It has 2 x SPDT integrated auxiliary switches
