Idemia recommends using a AWG16 gauge and 24V power supply.
The voltage specified is the one measured on the product block connector:
12V-24V (-15% / +10%).
The voltage drop due to the cable shall be taken into account. The following table shows the maximum
distance between power supply and one (1) unique device, depending on cable gauge and power supply
