4.2. Power supply connector
The Ekinox can be powered by a DC voltage from 9 to 36 Volts. For best robustness and to reduce power
consumption, the internal power module is a high efficiency isolated DC/DC converter.
Apply a constant power supply to VIN+ and VIN- pins. The shield is directly connected to the device
mechanical enclosure. It should not be used as the ground return signal.
4.2.1. Connector specifications
The power supply uses a 2 ways male AluLite Fischer connector which is compatible with the Fischer Core
Series. The exact receptacle reference is: AL1731-DBPU-103-Z051PB11-12G13
This size 103 connector mates with the following plugs references in AluLite or Core Series. Alternative
plugs can be found if required (eg short plug). Don't forget that these two references don't include the cable
clamp sets.
●
AL1731-S-103-Z051SR11-11 (AluLite version)
●
S-103-Z051-130 (Core Series version)
Note: Although Fischer connectors are IP68 and specified to operate from -40°C to +75°C, the plug
should be connected at temperatures above -20°C and in a dry environment.
Warning: The power receptacle uses male connectors for obvious security reasons. Please make sure
that you order the correct plug reference.
