™

The ElectriFly™ Power Supply is great for a wide range of applications as it is capable of maintaining 12 amps output current at
12V DC. This power supply delivers clean, smooth, reliable power and is directly compatible with the entire line of ElectriFly Triton
chargers, as well as other chargers and a huge variety of other DC devices.

™

IMPORTANT PRECAUTIONS

• Do not allow water, moisture or foreign objects into the power supply.

• Do not cover the air intake, fan, and other vent holes. This will cause the power supply to overheat.

• Do not exceed 120V AC input.

• Do not leave the power supply connected to AC when unused.

• Do not open or attempt to repair the power supply at any time. Contact Hobby Services for any and all repair needs .

• Keep out of reach of children.

AC INPUT POWER

The ElectriFly 12 Amp Power Supply accepts po wer from a 110V A C source. This is a “switching” pow er supply as opposed to a linear
power supply which employs a high frequency switch-mode design to convert 110V AC input to a fi xed 13.8V DC output. This state­of-the-art technology allows the power supply to operate entirely without a big, heavy internal transformer and results in a very small,
and lightweight device that can deliver a tremendous amount of power. This technology also generates highly effi cient and clean DC
output. This is especially valuable today as many R/C chargers utilize peak detection designs which are very sensitive and demand
the cleanest power sources possible in order to maintain error-free operation.

POWER SWITCH

The power switch has a red LED to clearly show when the switch is in the on position. The LED does not illuminate when the switch
is in the off position. It’s recommended to turn the power supply off when not in use to extend its lifespan.

COOLING FAN

The cooling fan is controlled by a sensor and will switch on and off as needed as heat within the power supply rises and falls. The fan does
not operate at all times when the power switch is turned on.

CASE

The case is vented to allow suffi cient air-fl ow for proper cooling. ALWA YS hav e at least one inch of unobstructed area around the case
to allow the fan to properly cool the power supply.

WARNING: NEVER set any objects such as nuts, scre ws, w ashers, etc. on top of the case because they could very easily fall through
the vents and cause permanent damage to the power supply.

WARNING: NEVER stack a charger or an y other device on top of the case as it will prohibit proper cooling and could cause permanent
damage to the power supply.

CONNECTING EXTERNAL DEVICES

Always connect the red (+) positive lead from y our charger or other external device to the red (+) positiv e terminal on the power supply,
and the black (-) negative lead from your charger or other external device to the black (-) negative terminal on the power supply.

Note: The black and red terminal caps can be unscrewed and removed if needed.
WARNING: Do not allow wires or other metal objects to accidentally make contact simultaneously with both terminals, as a short

circuit condition will exist.
WARNING: ALWAYS ensure polar ity is correct when connecting external devices to the power supply. Reverse polarity will not

damage the power supply but it may damage the external device.
WARNING: NEVER attempt to connect batteries directly to the output of the power supply!

SAFETY FEATURES

The Electrifl y 12 Amp Power Supply has a 12 amp solid-state current limiter for overload protection, plus short circuit protection. If
either of these conditions occur, disconnect the supply from the A C input, w ait appro ximately 15 seconds to allo w the device to reset,
and then re-connect to the AC input.

A built-in top mounted cooling fan keeps electronics cool to help maintain optim um effi ciency and e xtend the life of the power supply.
WARNING: Do not b lock the air v ents on the po wer supply. Make sure there is ample room f or air to enter and lea ve the po wer supply

so heat can dissipate effi ciently.
