The SNS15 is a battery-backed electric actuator designed for critical applications requiring fail-safe operation during power loss. It delivers 1,500 in-lb (169.5 Nm) torque with a 30-second 90° cycle time and supports 100% duty cycle. Powered by a 12Vdc brush motor, it operates on 12Vdc, 24Vac/Vdc, 115Vac, or 230Vac inputs, drawing 2.30A full load and 4.20A lock rotor. An integrated 12V 0.8Ah sealed lead-acid battery provides up to five 90° cycles per charge, recharged by a trickle charger. The actuator features a universal mounting pad compliant with ISO 5211 F10, a visual dome position indicator, snap-action SPDT limit switches rated at 15A at 250Vac, and a manual override hand wheel. It has a NEMA 4 enclosure with optional NEMA 4X, 7, or 9 ratings, a thermally bonded polyester powder coating, and operates from -40°F to 150°F (-40°C to 65.6°C). It weighs 22 lb (10 kg).
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.
