T.A.C. MP-381-0-0-2 Actuator

The T.A.C. MP-381-0-0-2 Actuator is a heavy-duty, oil-submerged proportional actuator engineered for precise control of HVAC dampers and valves. Operating on a 24 VAC power supply with a 2.2 Amp draw, this non-spring return actuator delivers a high-torque output of 220 lb-in, making it ideal for large-scale air handling and fluid control applications. The unit features built-in feedback potentiometers for accurate positioning and is housed in a rugged NEMA 1 die-cast aluminum enclosure. Designed for versatility, this model supports floating control and proportional signals, facilitating seamless integration with Barber-Colman Microtherm series controllers. The "0-0-2" suffix confirms CE compliance and includes the latest internal wiring updates for improved signal stability. With a wide operational temperature range of -40°F to 136°F, this Schneider Electric compatible component ensures reliable performance in demanding mechanical environments, providing the durability necessary for critical commercial building automation infrastructure.

• High Torque Performance: Delivers 220 lb-in of torque to manage large dampers and heavy-duty valve linkages without stalling.
• Oil-Immersed Gear Train: The internal motor and gear assembly are submerged in oil to provide continuous lubrication, reducing wear and ensuring quiet, maintenance-free operation.
• Precision Feedback: Integrated 100-ohm feedback potentiometers allow for exact stroke monitoring and refined proportional control.
• Robust Environmental Tolerance: Rated for operation down to -40°F, ensuring reliability in cold-start HVAC scenarios and outdoor-to-indoor air intake systems.
• Flexible Input Support: Compatible with SPDT snap-acting switches, electronic actuator drives, and various 135 to 1,000-ohm slidewire controllers.

What is the difference between the -0-0-2 model and older MP-381 versions?
The -0-0-2 suffix indicates that the unit is CE compliant and typically features updated terminal connections. Unlike older factory models where transformers were wired directly to the potentiometer, the -0-0-2 series is designed for easier field wiring and better interference shielding.

Can this actuator be used in hazardous locations?
The standard MP-381-0-0-2 is a NEMA 1 unit. For hazardous environments requiring explosion-proof protection, a specific cast aluminum housing with 3/4-inch pipe tapped openings must be utilized, though the internal gear train technology remains consistent.

Is this a spring-return or non-spring return model?
This is a non-spring return (NSR) actuator. It will maintain its last position upon loss of power unless it is integrated into a system with a specific fail-safe backup or manual override configuration.
