APPLICATION
The ML6284 Non-Spring Return Direct Coupled Damper
Actuator provides single pole double throw (spdt) floating
control of dampers in heating, ventilation, and air conditioning
(HVAC) applications. The actuator has an internal,
electrically isolated feedback potentiometer that can be used
to provide indication of the motor output hub position or
control a slave Series 90 actuator.

Non-Spring Return
FEATURES
• Mounts directly on 3/8 in. to 5/8 in. (10 to 17 mm) round
and square and 3/4 in. (19 mm) round damper shafts by
using the appropriate insert. Most models are shipped
with 1/2 in. insert.
• Provides 150 lb-in. (17 N•m) running torque.
• Magnetic coupling eliminates the need for mechanical
stops or limit switch adjustments by limiting stall
torque to 250 lb-in. (28.3 N•m) maximum.
• 95° stroke provides necessary compression of
rubber/neoprene gaskets commonly used on 90° low
leakage dampers.
• Manual clutch allows for manual adjustment.
• 92-second synchronous timing can eliminate need for
feedback position indication in closed-loop
temperature control applications.
• Removable splined output hub permits premounting of
hub on damper shaft, providing installation flexibility.
• Designed for both single-point and three-point
mounting, to allow installation flexibility.
• Available with or without a time-out feature. Models
without the time-out feature are designed to be used
with intelligent building management system and/or
controller.
• Standard models have two 8 mm by 12 mm long set
screws for securing the damper shaft. Actuator models
available for various shaft sizes that allow damper
shaft to operate centered inside the output hub.
