The Balmar XT-SF-24-90-K6 alternator from the XT series delivers 90A at 24V and was specifically developed for yachts, larger motorboats, and vehicles with 24V electrical systems. For those who want to operate a powerful, modern 24V electrical system today - including a lithium battery bank - this alternator with single-foot/spindle mounting (1-2″) offers a compact, reliable charging solution that can be integrated without extensive modification of the engine mount.
Advantages of this alternator at a glance
- 90A charging capacity at 24V for significantly more on-board power capacity than conventional alternators
- Compact small-case housing - fits even in confined engine compartments
- Modern braided winding design with 96 instead of 36 slots - generates more electromagnetic energy and efficiency than the older AT series
- Consequently runs about 5-10°C cooler than AT-Series models - protects windings and electronics and extends service life
- Dual-fan cooling ensures high air flow even under continuous load
- Patented Smart Ready® technology with integrated regulator as basic protection/fallback
- Explicitly suitable for use with lithium battery banks
- Certified according to USCG Title 33, ISO 8846 and SAE J1171
Technical Data & Compatibility - will it fit my engine?
- Charging power: 90A at 24V
- Mounting type: Single Foot, bracket width 1-2″
- Pulley type: K6, 6-groove serpentine pulley
- Balmar Part Number: XT-SF-24-90-K6
- Generally, an AltMount© pulley conversion kit for serpentine belts is required, unless the engine already has a dual V-belt or serpentine pulley
- For non-adaptive speed display, a tachometer signal stabilizer (Balmar 15-TSS) may also be required
Single or as a Set - what's the difference?
In the "single" variant, you receive only the XT-SF-24-90-K6 alternator. In the "set" variant, we also supply the suitable MC-624 multi-stage regulator for 24V systems including temperature sensors - giving you a complete, coordinated charging solution from a single source and saving you the separate procurement of a regulator.
Area of Application
This alternator is particularly suitable for 24V yachts, larger motorboats, catamarans and commercial vehicles with increased power requirements on board, for example due to refrigerators, electronics, bow thrusters or lithium battery banks.
Upgrade your 24V electrical system now with the powerful and reliable Balmar XT-SF-24-90-K6 - order individually or as a complete set with regulator.
