External Power Supply:
12-24 Volts (regulated and filtered) 2.5 Amp min @12 V, CEE/EEC EN60950
standard compliant. If sharing power between devices, each unit must receive 2.5 A (e.g. two units would
require a 12 VDC, 5 A supply).
Power Over Ethernet (POE+):
power can be provided through RJ-45 connector
using a PSE (Power Sourcing Equipment)
IEEE802.3at type 2
compliant.
The terminal is a Class 4 (25.5 W) PD (Powered Device).

IDEMIA recommends using a 24V power supply and AWG16 gauge
cable. The voltage measured on the product block connector of the
terminal must be equal to 12V-24V (-15% / +10%).
The voltage drop due to the cable shall be taken into account. The
table at the right, shows the maximum distance between power
supply and 1 unique device, depending on cable gauge and power
supply rating.
