Note:
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 30 VDC peaks, high voltage power supplies can harm the device.
