Elma Electronic Designs Supply Module for Harsh Environments

Global electronic systems manufacturer Elma Electronic UK has designed a conduction-cooled power supply module to meet the requirements of VITA 62 for use in harsh environments for 28V DC input. This is a 6U-5HP (1in) module with guide block for use in VPX systems.

The modules can be easily customised to suit individual requirements, and are always closely designed with the complete system design to ensure the best EMC performance of the overall system. The power supply modules incorporate custom machined cold plates to ensure high mechanical strength as well as optimum thermal performance.

The power supply modules are suited to the most demanding applications such as those found in vehicles, fast jets and naval applications where extremes of temperature, vibration, shock, humidity and EMC sealing to MIL-STD-810 are of critical importance. The features of the new module include:

  • 6U plug-in module with VITA 62 compliant connector and guide pins
  • 5in HP wide (1in pitch slot)
  • Five segment wedgelocks for increased thermal performance
  • Up to 750W output power
  • No minimum load requirements
  • Efficiency > 80%
  • Integrated input filter
  • Input transient protection
  • Operational temperature range -40°C to +85°C
  • Storage temperature range -40°C to +85°C
