Honeywell Direct Coupled 30 in-lb. Spring Return - MS4604F1010/U

The Honeywell Direct Coupled 30 in-lb. Spring Return Actuator is a versatile, 230 VAC unit with a power rating of 29.9 VA. This two-position, SPST actuator features a reversible mounting design, allowing for use in both clockwise and counterclockwise spring rotation.

The optimized housing design facilitates flush mounting to the damper, making for a smoother and streamlined installation. This actuator is built to function reliably in smoke control systems and carries Underwriters Laboratories Inc.'s UL555S ratings, approving for temperatures up to 350°F.

Varieties of this unit include models with SPST position-indicating switches, providing options for a 7-degree and 85-degree stroke. Essential to its operation, the actuator integrates a spring return mechanism to maintain a consistent level of return torque, a process which takes approximately fifteen seconds.

This robust piece of equipment is designed for enduring use and does not require special cycling during long-term holding. Moreover, it operates silently during holding. This patent-pending design also circumvents the need for limit switches, thus reducing overall power consumption.

Models compatible with different voltages - 24, 120, and 230 VAC - are available, ensuring usability across varied power supply setups. The actuator can accommodate up to a ninety-five degree angle of rotation and can reliably hold the rated torque even at reduced power levels.

The technical specifications of the device are extensive. With a power consumption of 29.9 VA, this actuator is designed to operate under conditions ranging from 0°F to 130°F, or -18°C to 55°C. Color-coded leads provide a straightforward electrical connection, and the unit features robust aluminium housing for durability.
