Energy Generation





Long term reliability is at the core of our design philosophy. The best-in-class power supply successfully addresses the electrical havoc present in vehicular power systems. It rejects load dumps, repeated transients and over voltage. The high density extrusion becomes the heat sink for the CPU and other heat producing components. Environmental sealing blocks dust and moisture entry. The unique thermal design and industrial grade components allow fanless operation over a -40° C to 75° C range.

A unique design tightly integrates the electrical, thermal and mechanical components into a complete system with no compromise to any one segment. It was designed for applications where severe environments and high performance meet.

The RMB-C2B excels in demanding applications like military, mining, drilling, energy generation systems and other applications where the cost of failure can be unacceptably high. The careful circuit design, component selection, testing and superior heat dissipation maximize reliability and minimize costly downtime.

Shock and vibration are blunted by a shock plate design based on more than 20 million field hours with CORE Systems products. The shock plate employs a sophisticated “cradling” system to deal with 24/7 vibration. The custom mechanism includes both absorbing and dissipative material to reduce component fatigue, pushing the envelope on reliability in extreme applications.

The fully developed & proven platform accelerates your design process. It can be supplied with Windows XPe or Linux installed with all drivers.

Custom versions can be readily developed to meet your specific applications with the use of an 18 pin unpopulated option connector. The modularity of the RMB-C2B enables custom functionality with COTS ruggedness without large up-front costs.
