Electrical Specification
3.2.1
Supply Voltage Characteristics
The MB-COME6-4 requires an input voltage of 12 V DC ±5 %.
The input voltages shall rise from 10 % of nominal to 90 % of nominal within 0.1 ms to 20 ms (0.1 ms ≤ Rise Time ≤ 20 ms).
There must be a smooth and continuous increase of each DC output voltage from 10 % to 90 % of its final set point within
the regulation range.
3.2.2
Power Consumption Specification
The power consumption of the system significantly depends on the connected devices; e.g. COM Express™ module, mass storage
devices, USB devices, display backlight, etc.
The power consumption of the MB-COME6-4 itself is approximately 2 W (COM Express™ module supplied externally);
UEFI-shell active; no keyboard, no mouse, no mass storage device, no Ethernet cable etc. connected).
Note: Power requirement
The MB-COME6-4 input current is not fused. The user has to ensure that the input current does not exceed the
maximum current of 25 A (300 W).
Additionally the power supply must be configured with enough reserve. It should be calculated with the
maximum power consumption of all connected components.
