BL1 Medium Actuator 24 VDC – AT7851
The AT7851 actuator is a 24V DC telescopic column specifically developed as a replacement part for Noval's 3-stage stainless steel electric table pedestals. Designed to deliver smooth and controlled elevation, it operates at 24V DC and is built for the demanding conditions of marine environments, where durability and corrosion resistance are paramount.
This actuator is compatible with a wide range of Noval pedestal references—both current and legacy systems—and allows easy maintenance or upgrade of the lifting mechanism without replacing the full pedestal. The polished stainless steel aesthetic of the matching pedestal bases makes this actuator particularly suitable for installations in luxury yacht saloons, cockpits, or flybridges where elegance meets utility.
The AT7851 is delivered without its power cord (reference: AT7852), which must be ordered separately if needed. Electrical control can be managed via standard polarity reversal (MOM OFF MOM switch – reference: NL1494) or through Noval's radio (reference: AT5189) and synchronization modules (reference: NL2120).

Our review
✔ Pros
- Reliable and smooth lifting operation in marine-grade applications
- Direct replacement for numerous Noval stainless steel table lifting systems
- Operates on 24V DC, suitable for modern yacht energy systems
✘ Cons
- Power cable not included (must be ordered separately if necessary – AT7852)
- Limited to pedestal compatibility (NOVAL 3 stages stainless steel electric table lifts)
Conclusion
The AT7851 is an essential spare or replacement actuator for any Noval stainless steel electric table pedestal using a BL1 Medium configuration. Its robust construction, 3-stage lift design, and smooth 24V operation make it a premium solution for maintaining or upgrading your yacht’s modular furniture systems.
Good to Know
- For remote or synchronized operation, pair with AT5189 radio transmitters and NL2120 control modules.
- Power cord (ref. AT7852) is required and sold separately.
- Ensure compatibility with listed pedestal models before installation.
- Recommended for use in saloons, cockpits, or flybridges on premium yachts.
- Observe Noval installation guidelines for optimal performance at sea. Guidelines and technical specifications are supplied with the system and downloadable right after confirming your purchase on nauticspares.com.
