blue!smart basis system

Conventional MicroTCA systems are only conditionally suitableor not at allwhen used under extreme load conditions. Elma Electronic has developed its new blu!smart basis system specifically for such ruggedized applications and for intensive testing of advanced mezzanine card (AMC) modules under such tough conditions. It is mounted on a flat surface using four flange holes and, for instance, can be mounted on walls and panels in industrial environments.

Exhaustive testing has confirmed that the AMCs in the system remain firmly fixedeven when subject to significant shock and vibration.

The new basis system is functionally compatible with the MicroTCA specifications. However, for ruggedized applications, card guides developed by Elma are installed in the chassis. Vibrational and shock tests were performed as follows:

??Random vibration according to AC2-VITA 47;

??Frequency range 5Hz-2,000Hz in three axes, rms value of the acceleration 8g, duration per axis 60mins.;

??Shock according to AC1IEC 61587-1.

??Semi-sinusoidal waveform for six axes, acceleration 25g, application time 18ms, three shock loads for each axis.

All of the AMC modules and the MCH were still firmly fixed in their slots unchanged at the end of the test. The interruption-free electrical contact to the backplane via the gold pads was guaranteed and the undisturbed module operation secured. This means that the MicroTCA blu!smart basis system is optimally suited for use under extreme conditions.

In addition to the rugged blu!smart chassis, the blu!box, blu!cube and blu!eco basis systems are available for MicroTCA applications running under normal conditions. The latter makes it possible to implement particularly cost-effective applications, as Elma has integrated parts of the MicroTCA management on an active backplane. This in turn enables more cost-effective power supply units to be used, but while still retaining full MicroTCA compatibility.
