New XT-Series Alternators from Balmar bring together the latest innovations in alternator design to deliver incredible charging power in a compact, Marine-friendly package.

The New XT-Series Alternator family features a state-of-the-art, braided stator wire design to generate exceptional output in the smallest possible area. The XT-Series produces slightly more power than our previous AT-Series 165A design and operates 5^o-10^oC cooler.  In addition, we’ve added Balmar’s Smart Ready^® internal regulator technology to provide an additional level of fault tolerance for cruising boaters.  Available XT-Series mounting styles have also expanded to include the “Vortec” 9Si design found on many GM gasoline engines.

XT-Series Alternators feature 96 slots – compared to 36 slots in a traditional S-wound stator – allowing the stator to develop superior electromagnetic energy and efficiency compared to traditional stator designs.  The XT-170 and XT-250 are designed to deliver superior performance at idle speeds – up to 128A and 186A, respectively for 12V applications.

XT-Series Alternators may require a Tachometer Signal Stabilizer (Part No. 15-TSS) if your current tach is not adjustable.  XT-Series Alternators should only be used in Dual Vee or Multi-Groove Serpentine belt configurations. Balmar’s growing range of AltMount^® Serpentine Pulley Conversion Kits support all XT-Series Alternators.
