# Technical specifications

This page describes the hardware and electrical characteristics of the IOcan CAN gateway. Higher-level protocol support, transmission-specific behavior, and configuration details are documented on separate pages.

## Power Supply and Electrical Characteristics

* Nominal operating supply voltage: 14.4 V

* Absolute maximum supply voltage: 18 V

* Maximum system current: < 20 A

* Internal fuse rating: 30 A

* Reverse polarity protection: Yes

* Wake-up voltage threshold: 4.5 V ± 0.3 V
