KMC MEP-4000 and MEP-4800 Series ControlSet Actuators
The
MEP-4000 series direct-coupled actuators represent a new generation of power in
diminutive size. These direct-coupled models offer 40 (MEP-40xx) or 80
(MEP-48xx) inch-pounds of torque and a variety of features in a compact
size. Perhaps most astonishing is that this power is available in such a small
package. The actuators measure just 5.3 inches long, 2.6 inches wide, and 2.5
inches high (135 x 66 x 63.5 mm). They weigh only 1.1 pounds (0.5 kg).
The MEP-4000 series provide tri-state or proportional control for small dampers
in HVAC systems. A minimum torque of 40 or 80 in-lbs. is available over the 95°
angular rotation.
The MEP-4002/4022/4802/4822 proportional actuator models accept a 0-10
volts DC control signal input from a thermostat, controller, or building
automation system. A user-initiated, auto-mapping feature provides better
equipment control by reassigning the 0-10 volts DC input signal range over a
reduced rotation range (from 45° to 95°). These models also feature a
switch-selectable, 0-5 or 0-10 volts DC voltage feedback output that is
proportional to the actuator position.
The MEP-4001/4013/4021/4801/4813/4821 tri-state models are designed for
use with floating thermostats, controllers, or building automation
systems. The MEP–4013/4813 models feature a 10,000 ohm (+/- 10%), three-wire
potentiometer feedback output.
The MEP-4021/4022/4821/4822 models also have a fully adjustable, built-in
SPDT auxiliary switch, for remote position indication or controller and
equipment interface.
All MEP-4000s mount directly to 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 non-rotation bracket, to prevent lateral movement,
is included with each actuator. A gear disengagement feature allows manual
positioning of the actuator.
