WARNING AND ERROR MESSAGE

INTRODUCTION

Thank you for purchasing the eFUEL 50A AC/DC Switching Power Supply. We are confident that
you will be very pleased with its performance because our AC/DC Switching Power Supply is designed
and manufactured by skilled professionals using the highest standard in workmanship. You can be
assured of many years of trouble free service.

1200W,

Your eFUEL AC/DC switching Power Supply is designed to use household AC power source to power
equipments that required DC power. The eFUEL converts standard household power 100-240V AC to 15­30V DC power and can supply up to 50 amperes of continuous power.

Active PFC: smaller AC input current less interference, and Conform to CE Regulations
One main DC power outputs, up to 50 amperes, three output(up to 10 amperes each) with ON/OFF switch.
Output voltage adjustable 15-30V
LCD indicates voltage and current amperes output
AC 100-240V worldwide operation: need not any alternative switcher, worldwide safe operation.
Two USB ports, 5 volts, 2100mA total for iPad, mobile phone, digital cameras and etc.
Smart cooling fans turned on upon the temperature automatically
Over current, over voltage, over load and over temperature protection
Short-circuit protection on output, safer and more reliable.

FEATURES

CONNECTIONS

Caution: Make all other connections before you connect the power supply to standard AC power

Turn the sleeves of the red and black binding output posts counterclockwise to expose the wire hole.
Insert the device's positive wire (usually red) into the red binding post's wire hole, then tighten the
binding post's sleeve to secure the wire in place.
Insert the device's negative wire (usually black) into the black binding post's wire hole, then tightening
the binding post's sleeve to secure the wire in place.
If you are using the banana plugs connection, insert the plugs into the terminal's jack.

Warnings: To avoid damage to both the power supply and the device:

Follow the correct polarity when connecting the power supply and the device.
Do not let the ends of the positive and negative wires touch each other.

OPERATION

To use the power supply after you connect the device to it, set POWER to turn it on with the power switch.
Please check all connections and confirm the wall AC outlet has power before you switch on the power
supply.
The LCD will display actual output voltage, current. If the voltage is NOT suitable for your charger or other
load, using the dial rotary to change the output voltage.

Your power supply's overload protection circuit automatically shuts down the power supply when it is
overload and resets by turning POWER to OFF.
If OCP or OPP shows on LCD screen, set POWER to OFF, reduce the load (by using a device that does
not require more than 1200 watts), then set POWER to ON.

To take advantage of eFUEL 1200W’s full power capability, the output voltage should be 24V DC or
higher. Per Ohm’s law, 24V x 50A = 1200W. Therefore, if you want to attain 1200W of output power, the
output voltage must set to 24V DC or higher.
The actual amount of output current feeding to the loading is also limited to 1200 Watts. If output voltage
is 30V, the max current is 40A.

Do not operate the power supply if it has been dropped or damaged in any way. Take it to a qualified
service technician for repair.
The power supply should be operated only from a standard AC outlet that provides 100-240V, 50/60
Hz. If you are not sure of the type of power supplied to your home, consult your local power company.
To protect the power supply during a lightning storm or when it is left unattended and unused for long
periods of time, unplug it from the AC outlet. This will prevent damage to the power supply from
lightning and power surges.
Unplug the power supply from the outlet before attempting any maintenance or cleaning. Do not use
liquid or aerosol cleaners. Use a damp cloth for cleaning and then wipe it dry immediately.
If your power supply does not operate normally, in particular if any unusual sounds or smells come
from it, unplug it immediately and contact a qualified service technician for repair.

Caution: To reduce the risk of damage:

IMPORTANT SAFETY INSTRUCTIONS

Danger: To reduce the risk of fire or electric shock, carefully follow these instructions. This manual
contains important safety and operating instructions for this power supply. Before you use the power
supply, read all the instructions and cautionary markings in this manual, on the power supply, and on the
product that you will connect to the power supply, to reduce the risk of injury:

Do not use the power supply near water (for example, a bathtub, washbowl, kitchen sink, laundry tub,
wet basement, or swimming pool).
Do not place the power supply on an unstable cart, stand or table. If the power supply falls, it could
injure a person or cause serious damage to the power supply.
Do not overload power outlets or extension cords. An overload can result in fire or electric shock.
Do not disassemble this unit; take it to a qualified service technician when service or repair is required.
Improper reassembly may result in a risk of electric shock or fire.
Do not use an attachment not recommended, this could result in a risk of fire , electric shock, or injury
to persons.
Never push any object into the slot in the power supply. It could touch dangerous voltage points or
short out parts resulting in a fire or electrical shock.

Caution: Your power supply might cause TV or radio interference even when it is operating properly. To
determine whether your power supply is causing the interference, turn off your power supply. If the
interference goes away, your power supply is causing it.

Try to eliminate the interference by:

Moving your power supply away from the receiver.
Connecting your power supply to an outlet that is on a different electrical circuit from the receiver.
Contacting a qualified service technician for help.
