Improved VR3 Regulators Available For Self-Excited Generators {4450}
Usage:
All Self-Excited Generator Sets
Description of Change: New regulators are now available which have improved immunity to electrical noise. This improvement reduces susceptibility to electromagnetic/radio frequency interference on the voltage regulator. With the addition of RFI filters these regulators meet the current EEC EMC (European) standards.
Adaptable To: The new 149-6130 Regulator Assembly (VR3 240V Self Excited) replaces the former 9Y8400 Regulator Assembly. The new 149-6131 Regulator Assembly (VR3 480V Self Excited) replaces the former 7C-2663 Regulator Assembly.
