||
| 8 | # Power Supply |
||
| 9 | |||
| 10 | IOcan is designed for permanent installation in automotive electrical systems and supports continuous connection to battery power. |
||
| 11 | |||
| 12 | ## Supply Voltage |
||
| 13 | | Parameter | Value | |
||
| 14 | |--|--| |
||
| 15 | |Operating voltage | 9–16 V | |
||
| 16 | |Recommended nominal voltage | 12 V automotive system | |
||
| 17 | |||
| 18 | The device should be powered directly from the vehicle battery through a fused supply. |
||
| 19 | |||
| 20 | Recommended fuse for vehicle installations: 30 A. |
||
| 21 | |||
| 22 | ## Quiescent Current |
