IMPORTANT SAFETY INSTRUCTIONS
INTRODUCTION
Your eFUEL switching DC Power Supply is designed to use mains electricity to power equipment that requires
DC power. The eFUEL converts standard household power 100-240V AC to 12-18V DC power and can supply
up to 30 amperes of continuous power.
Thank you for purchasing the eFUEL 30A Switching DC Power Supply. We are confident that you will be
delighted with its performance because our Switching DC Power Supply is designed and manufactured by skilled
professionals using the highest standard in workmanship.
Dual DC output ports are converted from banana connectors to XT60 battery connectors. It gets more
convenient & safe for charging the most popular battery with XT60 connector and avoid the possibilities of
reverse polarity.

Ensure that the power switch is OFF before connecting to the mains power socket. If the switch is ON,
your Power Supply may be damaged due to power surges.
Adjust the voltage by rotating the dial according to the loads. ( 12-18V)
Connect the loads. Please check the current of loads should not exceed 30 amperes. When the
current is over 30A, the Overload protection procedure will be activated. The Power Supply will cut off
the DC output and indicate "OCP" on the display. If you want to reset your Power Supply, TURN OFF
the Power Supply, reduce the loads after "OCP" disappear, then TURN ON.
Caution: Remove the output connections after use.
Caution: Place your power supply in a well ventilated open, and cool area. Do not block the fan
on both sides.
Caution: Your power supply might cause TV or radio interference even when it is operating
properly. To check whether your power supply is the reason causing the interference, turn off
your power supply. If the interference goes away, your power supply is causing it.
Try to eliminate interference by:
Keep distance between the power supply and TV or radio.
Connect the power supply to an outlet on a different electrical circuit from the TV or radio.
Contact a qualified technician for help.
