| **Parameter**                         | **Value**                                                                     |
| ------------------------------------- | ----------------------------------------------------------------------------- |
| Input voltage range (recommended)     | 6–13V DC                                                                      |
| Designed for direct connection to     | 2S or 3S lithium-ion/LiPo battery pack                                        |
| Input protection                      | Active over-voltage, short-circuit, reverse-polarity, inrush current limiting |
| GCS regulated supply (recommended)    | Triad Magnetics WSU120-2000                                                   |
| BEC ripple (if regulated supply used) | ≤3% of nominal output voltage recommended                                     |

> **Note**
>
> Somewear Labs has not formally qualified any commercial BECs for use with Horizon Hardware Units. A high-quality BEC with output voltage ripple of no more than 3% of its nominal output voltage is recommended. Conducted EMI from a low-quality power supply may adversely impact RF performance.

> **Caution**
>
> Do not operate the Horizon Hardware Unit with an unregulated input voltage of 6V for extended durations.
