The SNS6 is a battery-backed electric actuator with 675 In-Lb (76.3 Nm) torque and a 15-second 90-degree cycle time. It uses a brush-type 12Vdc motor and a rechargeable 12V 0.8 Ah sealed lead-acid battery with a minimum four-year standby life. Operating at 100% duty cycle, it includes a visual dome position indicator and snap-action SPDT limit switches rated 15A at 250Vac. Manual override is provided via a declutching hand wheel. The actuator is housed in a NEMA 4 enclosure with optional NEMA 4X, 7, and 9 ratings, features a thermally bonded polyester powder coat, and mounts to ISO 5211 F07 and F10 pads with a 17mm star drive. Weight is 22 lb (10 kg). Operation range is -40F to 150F (-40C to 65.6C); a heater is required below 0F.
Enclosure options include: NEMA 4, 4X, 7 and 9. The heavy-duty sand-cast aluminum enclosure has a thermally bonded ultraviolet resistant polyester powder coating that not only enhances its appearance but also is a tough corrosion resistant coating. Anodizing and epoxy coatings are offered as well.
NEMA 7 and 9 enclosures are perfect when the application requires equipment rated for Class I Groups C & D and Class II Groups E, F & G div. I and II environment. Despite a hostile environment, the Safe and Secure built in this explosion-proof enclosure can get the job done and lower the overall risk factor of the installation.
Safe & Secure Series is available in 115Vac, 230Vac, 12Vdc, 24Vdc, and 24Vac operating voltages to guarantee electrical compatibility and reliability with any process control around the world. It is equipped with 300 series stainless steel output shaft and heavy duty spur gear drive which, as in all ICI electric actuators, can withstand stall conditions without suffering gear failure.
