Description
The Bel SRXA-40AQ1L is part of the non-isolated dc/dc converter Power Module series. The modules use a
SMT package. These converters provide 4 outputs: 1.23 Vdc/6 A, 2.5 Vdc/1.5 A, 3.3 Vdc/1.5 A and -12 Vdc/2 A
over a wide range of input voltage (Vin = 10.8 - 13.2 Vdc).The efficiency is typically 91% @ 12Vin at full load.
