If you decide not to use the standard 9 VDC wall adapter and want to power the device from a higher voltage (15-30 VDC), please make sure that you choose a power supply of high quality. Some power supplies can produce voltage peaks significantly higher than the declared output voltage, especially during connection and disconnection.
While the device is designed to accept input voltage of up to VDC peaks, high voltage power supplies can harm the device. If you want to use high voltage power supplies it is recommended to also use additional safety equipment to suppress voltage peaks from the power supply.
Important: If you are using a power supply other than the one included with the device, ensure that it provides at least the same power output (W) as the original power supply. Using a power supply with insufficient power may prevent certain device features from functioning correctly. Refer to the device portfolio page under Power Consumption to verify the required power supply specifications.
Disclaimer: If additional USB devices or peripherals are connected to the device, their power consumption must also be taken into account. In such cases, a higher-capacity power supply may be required to ensure reliable operation of both the device and all connected USB accessories.
