The Balmar 94 Series Alternator with 2" single foot mount (Delco-style) is available in two powerful versions: the 94-12-210-IG with 12V/210A or the 94-24-140-IG with 24V/140A. Both variants are large, professional-grade alternators for boats with high power demands, large house battery banks, and demanding electrical loads under the harshest marine conditions.
Advantages
- Two selectable power variants: 12V/210A or 24V/140A — matching the respective onboard electrical system
- Extra robust windings, diodes, and carbon brushes for continuous operation under full load
- Isolated ground connections for safe integration into the onboard electrical system
- Corrosion-resistant, powder-coated surface for use in salty marine air
- Bidirectional cooling fan for reliable cooling regardless of rotational direction
- Meets USCG Title 33 ignition protection regulations for safe operation in the engine compartment
- Compact 2" single foot mount in the proven Delco style for uncomplicated installation
Which variant is right for me?
The choice between the two versions depends on your boat's onboard voltage: For a 12V system, choose the 12V/210A variant (94-12-210-IG); for a 24V system, choose the 24V/140A variant (94-24-140-IG). Both deliver maximum charging power for their respective voltage class from the same robust design.
Technical Data & Compatibility
- Variant 1: 12V / 210A
- Variant 2: 24V / 140A
- Mounting: 2" single foot (Delco-style) — compact one-sided mounting, unlike the 3.15" dual foot (Hitachi-style) of the 94LY series for Yanmar engines
- Maximum RPM: 7,000 RPM
- Pulley: Dual-Vee pulley, minimum size 1/2", Serpentine (K6/K8) optionally available
- Certification: USCG Title 33 ignition protected
Do I need an external regulator?
Yes, for both variants. The 94 Series is exclusively designed for operation with an external Balmar multi-stage regulator (e.g., MC-618 or MC-624, sold separately) — there is no internal regulator fallback in this series.
Application Area
Suitable for long-distance yachts, fishing vessels, racing yachts, and motor yachts with a large 12V or 24V onboard electrical system or lithium battery bank, where reliable charging under continuous load is crucial.
Since both variants represent the same powerful professional alternator in different voltage classes, we recommend checking the appropriate variant as well as the exact engine and belt configuration with philippi support before purchasing.
