ML6284
Non-Spring Return
Direct Coupled Damper Actuator
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.
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.
