TSUJ 109P0412NH3L4 Waterproof Cooling Fan

This TSUJ 109P0412NH3L4 is a new waterproof cooling fan rated at 12 V and 0.195 A. It suits equipment that needs a compact 4028 frame with moisture resistance. Builders working on sealed enclosures or outdoor electronics can use it for targeted airflow.

12 V DC Power Limitation

The fan operates only from a 12 V DC source drawing 0.195 A, so it cannot run directly from mains voltage or higher DC rails. Users without a regulated 12 V supply must add a suitable converter or controller. It is not suited for builds that require variable-speed PWM control or tachometer feedback unless those features are confirmed elsewhere.
