Kensington 150 manual Fuse Replacement, DC Power Source Requirements, AC Power Draw Guidelines

Fuse Replacement

Warning! Ensure that your Inverter is disconnected from the 12V DC power source before replacing the internal fuse. Failure to do so may cause electrical shock!

1.Your Inverter’s fuse is located inside the Inverter. Do not disassemble the cigarette plug adapter. Open the Fuse Door located on the bottom of your Inverter to gain access to the fuse.

2.Using a pair of needle nosed pliers (not included with your purchase) as demonstrated above, carefully remove the automotive blade type fuse.

3.Replace the fuse with a fuse of equal rating (20A 32VDC) and type. Do not use a fuse of a higher rating as this could result in damage to the portable electronic device you are powering or the aircraft/vehicle your Inverter is drawing DC power from.

4.To check or replace the fuse of the vehicle providing DC power to your Inverter please refer to your vehicle’s Owner’s Manual. Kensington recommends closely following the instructions and warnings provided by the vehicle’s manufacturer.

5.Determine the cause of the overload/short circuit before restarting your Inverter.

DC Power Source Requirements

Your Inverter must be connected only to vehicles with a DC power source rated at a nominal output voltage of 12 Volts. Your Inverter will not operate from a 6 Volt battery and will be damaged if it is connected to a 24 Volt battery. The power source must provide between 11–15.5 Volts DC. The power source may be a battery or other well-regulated 12Volt DC power supply. Check your vehicle’s Owner’s Manual.

The power supply must also be able to deliver the current necessary to operate the load created by the portable electronic device that you are intending to power. As a rough guideline, divide the power consumption of the device (in Watts) by 12 (the nominal input voltage) to obtain the current (in Amps) the power source must deliver. Example: If a device is rated at 120 Watts; the power source must be able to deliver:

(120/12) = 10 Amps. Most vehicular 12 Volt cigarette lighter outlets have fuses that will permit the outlet to draw between 15 and 20 Amps.

AC Power Draw Guidelines

Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in Amps or Watts. Be sure that the continuous power consumption of the device you wish to power is rated at 120 Watts or less. If the power consumption of the device is rated in Amps, simply multiply by the AC volts (115) to determine the wattage. For example, a power drill rated at 1 Amp will draw 115 Watts. Do not use your Inverter to operate a device that requires more than 120 Watts of continuous power.

Troubleshooting

“Buzzing” sound in audio systems—Some inexpensive stereo systems and “Boom Boxes” can emit a buzzing sound from their speakers when operated from your Inverter. This occurs because the power supply in the electronic device does not adequately filter the modified sine wave produced by your Inverter. The only solution to this problem is to use a sound system that incorporates a higher quality power supply.

Television interference—Your Inverter is shielded and filtered to minimize interference with TV signals. In some cases, some interference may still be visible, particularly with weak TV signals. Try the following corrective measures:

•Position your Inverter as far as possible from the television, the antenna and the antenna cables.

•Adjust the orientation of your Inverter, the antenna cables, and the TV power cord to minimize interference.

•Make sure that the antenna feeding the TV provides an adequate (“snow free”) signal and that high quality, shielded antenna cable is used.

Lack of AC power output—Some vehicle’s electrical systems require that when the vehicle’s engine is off the ignition key must be in the “on” or “accessory” position in order to power the cigarette lighter.

Blown fuse in your Inverter or in your vehicle’s 12V outlet circuit—Replace your Inverter’s fuse as directed in the fuse replacement section of this instruction guide. Refer to your vehicle’s Owner’s Manual for instructions on replacing blown fuses. Be sure that the Inverter is connected to a power source with correct voltage and polarity and the portable electronic device that you are intending to power does not require 120 Watts or more of AC power continuously.

Battery voltage below 11 Volts DC—Charge or replace your vehicle’s battery.

Equipment being operated draws too much power—Reduce load to maximum 120 Watts.

Inverter in thermal shutdown condition—Unplug your Inverter from the power source and allow it to cool down. Ensure there is adequate ventilation around your Inverter. Ensure that the device you are intending to power does not require more than 120 Watts of AC power for continuous operation.

Inverter not adequately warmed up—Plug your Inverter into your vehicle’s power source without the portable electric device plugged into the AC receptacle and allow your Inverter to warm up for 5 minutes in the ON position. Plug your portable electronic device into your warmed up Inverter. Repeat if necessary.

Inverter is overloaded—Reduce load to 120 Watts maximum to maintain regulation.

Low input voltage—Keep input voltage above 12 Volts DC to maintain regulation.

Low battery/Poor battery condition—Charge or replace your vehicle’s battery. See starting and running the vehicle’s engine section of this instruction guide.

Inadequate power or excessive voltage drop—Check the condition of your vehicle’s battery clips and terminals. Clean or replace, as necessary.
