On/Off Perko required. See diagram for wiring instructions. Get the best performance on your forward scan units with this voltage regulator setup to deliver a steady clean supply of 28 volts to all your forward scan modules. This unit meets the specs of Garmin LiveScope and Lowrance Active Target forward facing sonar devices. This unit is only for the black boxes and cannot be used on head units. This unit is designed to run off of existing 24v and 36v volt trolling systems in the boat and steps the current down or up to 28v. Increasing the voltage from 12v to 28v on your black box will yield better performance resulting in clearer, crisper imaging. This unit also reduces the amp draw of the units down over 60% causing lower operating temperatures so running units in packed rod lockers will help with temperature issues. Specs: Operating range input: 20v-45v Output voltage 28.4 at 10amps 10awg wiring Compatible with Garmin Livescope and Lowrance Active Target View hi-res versions of our wiring diagrams here and here.
