Automotive DC Power Cable with Cigarette Adapter
The SF-3040 receiver is protected from reverse polarity with an inline diode. It will operate on any DC voltage between 9 and 30 VDC, 6 W typical. The recommended voltage is 12 Vdc.
**Vehicular electrical systems that create voltage spikes in excess of 30VDC will benefit from providing power protection during vehicle engine power-up. This can be accomplished through a relay power-on sequence and/or power conditioning (such as a DC to DCconverter). Do not connect equipment directly to the vehicle's battery without in-line protection(such as a DC to DC converter).**
