Neptronic BT000 Actuator

The Neptronic BT000 is an industrial-grade damper actuator designed for reliable control in high-demand HVAC systems. Providing 50 in-lb (5.6 Nm) torque, this unit is engineered for 2-position (on/off) or 3-wire floating control configurations. Built with a robust non-spring return motor, the BT000 ensures stable positioning for air dampers and valve assemblies. It features a manual override button for easier field commissioning and a reversible rotation direction via a simple selector switch. This model is compatible with 24 VAC/VDC power supplies, making it a versatile drop-in replacement for standard non-spring return actuators. The compact housing is designed to fit in tight mechanical spaces while maintaining the thermal protection necessary for long-term operational integrity in commercial air handling applications.

Technical Specifications and Benefits

• High-Torque Performance: Delivers a consistent 50 in-lb of torque suitable for small to medium-sized dampers.
• Dual Control Logic: Supports both 2-position control and 3-wire floating signals for maximum system flexibility.
• Field Adjustability: Includes a manual clutch for manual positioning and a dip switch for changing rotation direction (CW/CCW).
• Direct Mount Installation: Features a universal clamp for fast attachment to round or square shafts.
• Low Power Consumption: Optimized for energy efficiency during active movement and holding patterns.

Common Questions

Is the Neptronic BT000 suitable for fail-safe applications?
No, the BT000 is a non-spring return actuator. It will maintain its last position upon loss of power. For applications requiring a return to a specific position during a power failure, a spring-return model is required.

What is the typical stroke time for this actuator?
The BT000 typically provides a 90-degree rotation in 90 to 110 seconds, depending on the load and power supply stability, ensuring smooth modulation without water hammer or air pressure surges.

Can I use this for both air dampers and valves?
Yes, while commonly used as a damper actuator, it can be coupled with compatible valve linkages provided the torque requirements do not exceed 50 in-lb.
