When connecting more than one device to the Hypsos power supply, you should consider the following: The combined power consumption of the two devices, the operating voltage and the polarity. The maximum power consumption should not exceed 80W and the current 6A.
For example, if you wish to power a Ferrum OOR as well as another device of your choice, the latter must be compatible with the OOR's power supply configuration, i.e., central positive polarity and 24V.
