Powerbox’s COTS/MOTS power supplies make meeting highly demanding applications a reality

9 MARCH 2017

PRBX_ruggedized-power_DAx-DBxPowerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced the release of its new Defense Line of ruggedized power solutions for highly demanding environments. The launch includes seven series of new power supplies, comprising three DC/DC (DAA-DAB-DAC), four AC/DC (DBA-DBB-DBC-DBD) and embracing a power range from 50W up to 1,200W. In metal chassis format with a baseplate for conduction cooling, the DAx and DBx series can be used with a baseplate operating temperature range of -40 up to +100°C. For extremely demanding applications they can be configured with a conformal coating and mechanically ruggedized as well as electrically ruggedizing to withstand harsh transients and demanding EMC performance requirements as required with most common defense, marine, avionics, rugged industrial and railway standards. Designed for high availability, short time-to-market and to meet commercial and military off-the-shelf (COTS/MOTS) business models, the modular build style of the DAx and DBx series allows up to six outputs which can be connected in serial, parallel or used as a standalone output – very versatile products.
Ready to use, Defense Line DC/DC DAA/DAB/DAC power supplies include a very efficient input filter, reverse voltage protection internal diode, input transient protection and an internal fuse to protect against damage in the event of failure. Each output is protected against accidental and permanent short-circuit situations. An internal over-temperature circuit (OTP) protects the units in the case of over-heating, with automatic recovery. To cover the large range of applications in defense or ruggedized industrial areas, the DAA/DAB/DAC series is available for use with five input bus voltages, 12, 24, 48, 72, and 110VDC and with a large range of output voltages from 3.3VDC up to 48VDC. Each output voltage is adjustable, and higher power outputs are compensated using the provided senses.
