Ruggedised 500W power supply for military use and other demanding applications
Released 28 April 2009

Elma Electronic UK has announced a range of high output ruggedised conduction cooled 3U and 6U, 5HP wide pluggable power supplies for use in military and other harsh operational environments such as road and rail vehicles, aerospace and maritime applications where extremes of temperature, vibration, shock, humidity and EMC integrity are of critical importance. Inputs are user-specifiable at 28VDC, 115VAC, 230VAC and 250-425VDC, with multiple DC outputs, typically +3.3V, +5V +12V and -12V, to suit various bus architectures including VME, cPCI, VXS and VPX. Form factors and connector options are also optimised to match the different bus specifications. The units incorporate custom-machined cold plates to ensure high mechanical strength as well as good thermal performance; 7-segment Wedgelocks assist with removing heat from the cold plate into the subrack framework.

While not all applications will require conformance to the full military environmental MIL-STD-810F Specification, these power supplies are specified as follows: altitude to 40,000ft, vibration to 5.6g RMS, shock to 40g, acceleration to 2 to 7 g, 6-axis, and humidity to 95% non-condensing. Meeting such demanding requirements demonstrates the integrity and long term reliability of the units.

Key features include current share for N+1 redundant operation; no minimum load requirement, a single connector interface, ejector handles and remote sense, PSU good and inhibit/enable functionality. The modular design enables easy customisation of the mechanical configuration and voltage rails with low front end engineering costs and rapid realisation to suit individual requirements.
