KMC MEP-4101 Direct-Coupled, ControlSet® Actuator (10 in-lb.)

Previous Page

mep-4000 series

This compact direct-coupled actuator controls small dampers in HVAC systems that require relatively high rotation speed and low torque. This three-wire tri-state actuator is designed for use with floating thermostats, controllers, or building automation systems. The actuator can rotate a damper 90° in 30 seconds (@ 60 Hz). A minimum torque of 10 in-lb. is available over the 95° angular rotation (with an adjustable end stop). Under the translucent cover, LEDs indicate (energized) open and closed states for position indication and troubleshooting. When the actuator reaches the end of rotation, the motor is disengaged, and (after about five seconds) the appropriate LED indicator illuminates—green for “power open” (CCW) or red for “power closed” (CW).

The LED remains on until:

  • Power to the terminal is simply removed

  • Power is switched to the other terminal, and the actuator starts turning again in the opposite direction.

 

The actuator mounts directly on 1/4 to 5/8 inch (6 to 16 mm) round shafts or 1/4 to 7/16 inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. A gear disengagement button allows manual positioning of the actuator.

 

Features:

  •  Quick damper opening and closing (30 seconds for 90° rotation @ 60 Hz)

  • Under the translucent cover, LEDs indicate (energized) open and closed states for position indication and troubleshooting

  • Adjustable end stop for min./max. position capability to allow adjustment of the design CFM flow into a zone

  • Direct mounting to standard shaft sizes

  • Gear disengagement button for easy set-up


Accessories are available:

  • HCO-1151 Weather shield kit
  • HMO-4001 Non-rotation “T” bracket
  • HMO-4002 Replacement non-rotation bracket
