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 switchesFeatures and BenefitsThe direction of rotation reversible Spindle driver universal spindle clamp Operating voltage ranges between 2VDC and 10VDC Running springtime is <20s PVC connection cable length is 1m Motor and return torque is 20Nm Maximum damper area is 4m² Damper spindle compatibility ranges between 10mm and 25.4mm Power consumption is 7W Noise level ??5 (Motor) dBA, ??2 (Spring Return) dBA Rated impulse voltage is 0.8kV Maintenance-free Service life min. 60,000 emergency positions Ambient temperature ranges between -30°C and 50°CCertificationsIEC/EN 60730-1 UL 60730-1A UL 60730-2-14 CAN/CSA E60730-1:02 IP54
