Product Summary

the Model SE350 Regulator is an exact replacement for the Marathon and Katolight SE 350 regulator. This fully encapsulated and repairable module is suitable for OEM applications as well as an economical replacement for many hard to find or obsolete regulators found on older generators.

It is easy to install, does not require field flash, and works with all single and three-phase 208-240 (or 12-lead 480V), 50 or 60Hz systems by connecting just four wires. Field or brushless exciter current of up to 3.5A is provided by a phase controlled SCR. The output voltage is automatically reduced during under-speed operation.
