Fast-acting, two-position actuator with 175 lb-in., 20 Nm spring return and 230 Vac
Overview
Honeywell's Fast-acting, two-position actuator with 175 lb-in., 20 Nm spring return and 230 Vac actuator accepts two-position control with an integral junction box and accepts an on/off signal from a single-pole, single-throw controller. Reliability operates in smoke control systems requiring UL555S ratings up to 350F.
Features
- 175 lb-in. (20 Nm) minimum driving torque at 350F (176C)
- Integral stainless steel spring return ensures return torque level
- Reversible mounting allows clockwise (cw) or counterclockwise (ccw) spring rotation
- Fifteen-second spring return timing
- No special cycing required and no audible noise during long-term holding
- Models available with integral high temperature (350 F) SPST position-indicating switches (<7 degrees, >85 degrees)
- Ninety-five degree angle of rotation for tight damper closure
- Actuator holds rated torque at reduced power level and die-case aluminum housing design allows flush mounting to damper
