WARNING AND ERROR MESSAGE
INTRODUCTION
Thank you for purchasing the eFUEL 1200W, 50A AC/DC Switching Power Supply V2. 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.
Your eFUEL AC/DC switching Power Supply is designed to use household AC power sources to power
devices that demand DC power. The eFUEL converts standard mains power of AC 100-240V to DC 15-
30V power and can supply up to 50 amperes of continuous power.
Dual DC output ports are converted from banana connectors to XT90 battery connectors. It gets more
convenient & safe to charge the most popular battery with the XT90 connector and avoid the possibilities
of reverse polarity.

AC 100-240V worldwide operation: need not any alternative switcher, worldwide safe operation.
Two USB ports: 5V/2.1A total for iPad, smart phone, digital cameras and etc.
Smart cooling fans: automatic temperature control.
Over-current, over-voltage, over-load and over-temperature protection.
FEATURES
Over temperature protection.
Over current protection.
Over power protection.
The power supply's overload protection circuit automatically shuts down the power supply when overloaded. To reset the
power supply, please TURN OFF the power supply, reduce the load after warning signs disappear, then TURN ON.
If OCP or OPP shows on the LCD screen, switch off the power, reduce the load after warning signs disappear, then turn
on again.
Helpful Tip:
When this unit is working with Revolectrix Cellpro Power Lab 8, to maximize its efficiency without damaging eFuel
1200W and Power Lab 8, please set the Power Source of Power Lab 8 as following:

To take full advantage of eFUEL 1200W’s 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 be set to 24V or
higher.
The actual amount of output current is also limited to 1200 Watts. If the output voltage is 30V, the max current is 40A.
Warning: Don’t adjust the output voltage when the power supply is working.
Or damage may occur to the charger.

Press and hold the rotary dial for 3 seconds, and the output voltage value will start to blink, then turn the dial clockwise
or counter-clockwise to change the value, press the dial rotary once to confirm the desired value.
If you don’t press the rotary to confirm for 5 seconds during the process, the power supply will take the present
value as your selected automatically.
NOTE:
How to Adjust the Output Voltage?
1. Ensure the power switch is OFF
2. Connect the load to the POWER SUPPLY
3. Plug the Power Supply into an AC outlet
4. Turn the power switch ON
