DC0438 - Digital Thermatic® Fan Switch with 1/4" NPT Sensor & 38mm Inline Adapter Kit

This kit is designed to manage your Electric Fans or Electric Water Pump (EWP^®) with professional precision. It features a 38mm inline adapter for easy integration directly into the engine's top radiator hose, alongside two thermal sensors for versatile installation options.

The switch handles 1 or 2 fans and is compatible with 12V or 24V applications (24V requires DC10534 relays). With dual-fan logic, Fan 1 starts at the set temperature, and Fan 2 activates 10 seconds later, ensuring your electrical system isn't overloaded during startup.

• 38mm Inline Adapter: Fits directly into the radiator hose; can be increased to 44mm or 50mm using optional sleeves (DC18510/DC18511).
• IP66 Protection: Dust-tight and protected against high-pressure water jets, ideal for engine bay environments.
• Noise Filter: Integrated electrical noise filter ensures high reliability in older or modified vehicles.
• User Friendly: Easy push-button temperature adjustment (40°C to 110°C) with a clear LED display.
