Characteristic Curves
Output vs. Temperature
180W convection cooled and 275W continuous with 200 LFM airflow, derate output power to 50% at 70°C.
Efficiency vs. Loading
The high efficiency is achieved by using LLC technology with CCM mode PFC topology, and synchronous rectifiers on the output in all of this family
models, minimizing switching losses.
