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.
