Derale DER16796 Fan Controller Pulse with Modulation

Beschreibung

Historically, cooling fans run at 100%, even when less airflow is needed, constantly turning on and off as the engine temperature changes. This reaction based temperature control system causes constant amperage spikes, excessive noise and premature wear. The Derale PWM fan controller continuously monitors your engine's temperature, therefore controlling the temperature and increasing the vehicles cooling efficiency, while reducing the amps used to do so. .
