Upgraded design features several improvements over OE unit to protect against two common failure modes: water intrusion and excess heat. Improved umbrella cover design provides module with stronger barrier against water intrusion. RTV sealant around heat sink and cover perimeter fortifies module against water intrusion. Larger-output power device mounted directly to heat sink improves heat dissipation to prevent overheating. Upgraded 2 oz. copper board increases conductivity and power dissipation to prevent overheating. Included wire harness undergoes extensive voltage drop testing to ensure proper performance. Manufactured in the USA.
