COMe Reference Carrier Type 6 / Specification

3.4 Electrical Specification

Supply Voltage

8,5V – 18V

Power Supply Rise time

» The input voltages shall rise from ≤10% of nominal to within the regulation ranges within 0.1ms to 20ms.

» There must be a smooth and continuous ramp of each DC input voltage from 10% to 90% of its final set-point

following the ATX specification

Supply Voltage Ripple

» Maximum 100 mV peak to peak 0-20MHz

Maximum Current

The maximum current on the COMe Ref. Carrier T6 inclusive the module and all other connector consumers must not

exceed 16A. That leads to a maximum power of 136W at 8.5V input voltage and 288W at 18V input voltage.

3.5 Environmental Specification

Ambient temperature

» Operating: 0°C to +60 °C

» Non-operating: -20 to +75 °C

Humidity

» Operating: 10% to 90% (non condensing)

» Non operating: 5% to 95% (non condensing)

3.6 MTBF

The following MTBF (Mean Time Between Failures) values were calculated using a combination of manufacturer‟s test

data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore calculation used is

“Method 1 Case 1”. In that particular method the components are assumed to be operating at a 50 % stress level in a

40° C ambient environment and the system is assumed to have not been burned in. Manufacturer‟s data has been

used wherever possible. The manufacturer‟s data, when used, is specified at 50° C, so in that sense the following

results are slightly conservative. The MTBF values shown below are for a 40° C in an office or telecommunications
