3.1. General
The Secraft power converter is an optional accessory, that may be ordered with any new
Seacraft scooter model FUTURE or GHOST or retrot to scooters from serial number 129 on.
Note!
Retrotting a scooter with the power converter requires that DPV is equipped

Look out for the e/o cord symbol in the scooter’s main screen. It tells you, that
the scooteris equipped with a power converter.
The power converter is integrated into the scooter’s electronic compartment and converts the
battery voltage down to 6-12 V.
You can choose during the dive between 5 levels of voltage output, tuned to correspond with
20%, 40%, 60%, 80% and 100% heating power of 12V systems.
It corresponds with voltage steps of 6.0V, 7.5V, 9.4V, 10,7V, 12V.
Power converter adapter cable
You may connect external devices to the power converter by means of the included adapter
cable (70 cm, from the DPV’s charging port to standard e/o):
Caution!
Only connect compatible external devices to the power converter:
• Operating voltage: 6-12 V
• Max. power drain: 140 W
