your moderate-power mixed-logic designs, DATEL's BMP-5/5-3.3/4-D24 (18-36V input) BMP-5/5-3.3/4-D48 (36-75V input) fully isolated DC/DC converters providing both 3.3V outputs. Housed DATEL's standard 0.5" metal packages, these duals simultaneously source Amps from their outputs Amps from their 3.3V outputs. Both outputs fully isolated (1500Vdc) independently line (±1.0%) load (±1.0%) regulated. Both models feature input filters, input overvoltage shutdown, input reversepolarity protection, output overvoltage protection, output current limiting, thermal shutdown. Both outputs controlled On/Off Control function (pin Volt output adjusted ±5%. Model DC/DC's deliver high efficiency (82%) fully specified +100°C operation. Their corrosion-resistant metal cases have non-conductive baseplates threaded inserts easy heat-sink attachment and/or mounting. These devices satisfy IEC950, UL1950 EN60950 safety requirements BASIC insulation. marking available "D48" models.
