INTRODUCTION
Thank you for purchasing the eFUEL 1200W, 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.
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 15-
30V DC power and can supply up to 50 amperes of continuous power.

CONNECTIONS
Caution: Make all other connections before you connect the power supply to standard AC power
1. Turn the sleeves of the red and black binding output posts counterclockwise to expose the wire hole.
2. 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.
3. 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.
4. 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.

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.

WARNING AND ERROR MESSAGE
In case of an error the screen will display the cause of error. |
|
|
Over temperature protection. |
Over current protection. |
Over power protection. |
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.
