ABSTRACT:
A remote power feed device for electronic equipment comprises two branches in parallel of which a first branch includes in series as many sets of Zener diodes as there are functional systems to be powered. The other or second branch includes one or more Zener diodes. Only the Zener diodes of the first branch conduct in normal operation, i.e. in the absence of any overcurrent. The supply voltage or voltages of the various subsystems of the same functional system are the voltage(s) across a common Zener diode or common Zener diodes of a common set of Zener diodes of the first branch.
