Information About SF24A-S2
The SF24A-S2 is a resilient fail-safe drive built to protect complex HVAC infrastructure from unexpected electrical grid failures. It utilizes a durable mechanical spring that forces the connected damper or valve to a secure state instantly when operational power drops. Designed for diverse facility applications, it mounts effortlessly onto direct-coupled shafts to translate electrical logic into smooth mechanical rotation. This actuator features two adjustable SPDT switches that trigger accurately when the stroke reaches specific open or closed thresholds.
Key Features:
-
Fail-Safe Spring Return: Drives equipment automatically to a secure default position during emergency power losses.
-
Extreme Rotational Torque: Outputs 180 lb-in of mechanical force to handle large-scale dampers and control valves easily.
-
Dual Switch Feedback: Integrates two SPDT contacts to signal centralized controllers regarding physical stroke completion.
-
Low Voltage Efficiency: Operates cleanly on a 24V AC or DC supply to maintain safe commercial panel environments.
-
Overload Protection: Shuts down internal motor power electronically if the mechanical stroke is obstructed aggressively.
-
Universal Actuation: Adapts flawlessly to both air distribution dampers and hydronic flow control valves.
The SF24A-S2 delivers the reliability and precision required for strict on/off regulation and dependable fail-safe HVAC automation.
