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.
Accessories are available:
HMO-4001 Non-rotation "T" bracket
HMO-4002 Non-rotation bracket (included)
HLO-4001 Crank arm kit
HCO-1151 Weather shield kit
