Efficiency (%)
Thermal image with hot spot at full load current with 30°C ambient; air is fl owing at 100
LFM. Air is fl owing across the converter from -Vin to +Vin at 48V input.
Identifi able and recommended maximum value to be verifi ed in application.
Typical Output Voltage (Vout) vs. Input Voltage (Vin) at +25°C
The RBE-12/20-D48 is not designed to be operated within the shaded area.
The output voltage will be fully regulated within the white area in the graph
above. Operation outside of this area is not recommended for normal use.
