MBOX-ADVANCED FUNCTION
4.1
Power Supply
4.1.1
Supply Voltage
The MBox-Advanced has a wide-range voltage input of 9 V to 36 V DC.
4.1.2
Power Consumption
The power consumption of the system significantly depends on the configuration and the connected devices (COM Express™
module, mass storage devices, USB devices etc.). The maximum input current of the MBox-Advanced is limited to 5 A by a fuse.
All USB devices connected to the MBox-Advanced should not exceed 5 W in total.
Note: MBox-Advanced power requirement
The power supply for the MBox-Advanced must be configured with enough reserve.
When selecting the power supply, the maximum power consumption of all components
must be taken into account.
4.2
Environmental Conditions
The following temperature parameters were determined by qualification tests (standard configurations without add-on cards,
but with I-Temp mass storage):
•
Storage temperature:
–40 °C to +85 °C
•
Operating temperature:
–40 °C to +60 °C or 0 °C to +60 °C (depending on COM Express™ module)
•
Relative humidity (operating / storage):
10 % to 90 % (not condensing)
When I/O extension modules or HDD/SSDs are selected, attention has to be paid to their storage and operating temperature
limits. The temperature inside the MBox-Advanced differs from the ambient temperature.
Note: MBox-Advanced environmental conditions
When powering the MBox-Advanced, make sure the chassis is not covered by any objects.
Otherwise the heat dissipation will be restricted by physical effects and the maximum operating
temperature will be reduced.
