Newmar 12-12-3i Power Stabilizer

The Newmar Power 12-12-3i power stabilizer supplies regulated DC output for electronics that should not see wide battery-voltage swings. It is built for marine use in an anodized aluminum case and provides input-to-output isolation to reduce conducted line noise and support mixed grounding arrangements.
