SPER ZAGREB

We are a small Croatian manufacturer that has been producing high-quality replacement three-phase HVSP regulators/rectifiers for over 15 years with a special combination of series and parallel type regulators that reduce unnecessary heating of the stator and the regulator itself.

    Our best-selling regulator is the 14V-3FHVSP-30A-AX/BX-KS-LI (14.45V/14.7V, 30A, high rpm), which is also an alternative for the Shindengen SH847 up to 30A current. Warranty 4 years.
