Preliminary Description The DBB, very compact and low profile 600W AC/DC power supply in chassis format, incorporates input filtering, input and output protections, very robust mechanical mounting and connection, conformal coating and MIL-STD options required in most of the severe environment for industrial, defense applications. The PSU provides high reliability, high efficiency, input-to-output isolation, soft start and active very low inrush circuit, overtemperature protection, input over/undervoltage lockout. The PSU is configurable with 1 to 3 outputs in many output voltages from 3V3 to 48VDC, other outputs are even possible as semistandard versions, they are countinuously short-circuit proof. The 100°C baseplate allows operation in high temperature environment. Features 85-264 VAC input voltage ranges , PFC 1-3 isolated outputs 200*127* 40mm very low profile Industrial or ruggedizzed versions Active very low inrush current Many output configurations available Conduction cooled 100°C baseplate Safety IEC/EN 60950-1, RoHS lead-free-solder compliant Options Description MIL-STD ruggedized (-M) Meet MIL-STD 461E CE102, MIL-STD 1399-300A, MIL-STD810E shock & vibrations. No laboratory certification. -40°C operation (-T) The thermal grade of the DC/DC converters used and other components are changed to comply with low ambient temperature. Conformal coating (-V) During manufacturing process , when V option is specified, components and pcb are covered with an acrylic coating to address high level of ambiant humidity application. Heatsink (-H, -H1) -H: a 15 mm heatsink is mounted on the baseplate with longitudinal fins. -H1: a 15 mm heatsink is mounted on the baseplate with transversal fins.
