Electrical Specification
4.1.1
Supply Voltage Characteristics
The MBox-R/V supports a wide-range voltage input of 9 to 36 V DC.
4.1.2
Power Consumption Specification
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-R/V is limited to 5 A by a fuse.
The devices connected to the carrier should not exceed 30 W.
Note: Power requirement
The power supply for the MBox-R/V must be configured with enough reserve.
It should be calculated with the maximum power of all connected components.

Temperature Operating / Extended:
The maximum operating temperature depends on the internal power dissipation which is mainly influenced by the
CPU version. The following temperature parameters were determined by qualification tests (standard configurations
without any add-on cards):

MBox temp range
–40 °C to +60 °C
–40 °C to +70 °C
The supported operating temperature range depends on the components and modules used, e.g. if the temperature of the
COM Express™ module is in the range of 0 °C to +60 °C, the maximum operating temperature range is 0 °C to +60 °C.
•
Storage temperature:
–40 °C to +85 °C
•
Relative humidity (operating / storage):
10 % to 90 % (not condensing)
Note: Environmental conditions
When powering the MBox-R/V, 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.
