Lenmar offers innovative products for consumers and encourages the safe and proper use of each power accessory to achieve the maximum performance of the product and the devices it powers. Read these instructions carefully to safely use your N-Verter.

Lenmar’s N-Verter is an electronic device that converts low voltage DC (direct current) electricity from a battery to 110/120VAC (alternating current) standard household power.The AC output of this product is a modified sine wave with a voltage of 110/120 volts. With your Lenmar N-Verter you can power your laptops, computerized games, cell phones, camcorders, power tools, reading lamps, fans, and more.

Important: Before using your N-Verter, read and understand this owner’s guide. Save these instructions–this owner’s guide contains important safety instructions.

Troubleshooting

 

 

 

Symptom

Problem / Solution

An AC device is connected

The AC device has higher wattage demands or requires

and turned on causing the

a larger start-up surge current than the N-Verter’s

N-Verter to shut down

maximum rating can allow.The N-Verter unit is too

immediately.

small for this device. A higher rated N-Verter is needed

 

to deliver the power that the AC device demands.

 

Otherwise, use only lower power AC devices.

 

 

Green LED on the N-Verter

On many vehicles, the ignition key must be “on” for

unit does not light and/or the

power to be present at the cigarette lighter socket.

AC device does not operate

Make sure the key is on.

 

 

 

The N-Verter plug tip may be fitting too loosely. Use the

 

slide control on the plug tip to adjust and ensure a snug

 

fit and re-insert.

 

 

 

Battery voltage may be too low. Recharge the vehicle’s

 

battery and attempt again.

 

 

 

Vehicle fuse may be blown. Replace the vehicle’s fuse

 

with the same type and rating. Make sure you are not

 

overloading the socket or the fuse will blow again.

 

 

Buzzing sound in

Many inexpensive stereos or portable players will buzz

audio systems

when connected to the N-Verter because the modified

 

sine wave of the N-Verter is not properly filtered by the

 

electronic device’s power supply. Higher quality devices

 

will not buzz with the N-Verter.

 

 

Television

If the television signal is weak, the use of the N-Verter

interference

will cause a visual disturbance. Move the N-Verter away

 

from the TV, antennae and/or the antennae cables.You

 

may attempt to merely adjust the placement of the

 

antennae or cables. Inferior antennae and cables will

 

also cause TV interference during operation of the

 

N-Verter.

Safe Operating Guidelines

WARNING! Shock hazard The N-Verter generates the same AC power as a normal household wall outlet.

Operate only in ventilated area away from flammables, flames and accumulating dangerous or explosive fumes

Do not expose unit to water, rain or snow

Always turn OFF unit by removing it from the DC cigarette lighter outlet when not in use

Avoid exposure to direct sunlight and extreme temperatures (60-80°F or 15-25°C)

Do not insert foreign objects into the outlet.

Do not open the unit: no replaceable parts inside

Consult motor vehicle’s manual to determine cigarette lighter socket’s maximum power rating and fuse rating before attempting use in vehicle.

Unit will not and should not operate heat-generating appliances such as hair-dryers, microwave ovens, electric blankets, toasters, etc.

Compatible only with vehicles that have 12VDC Negative Ground electrical systems Failure to follow the above may result in personal injury or damage to the N-Verter.

Special Features:

NVD150S – A swivel tip design allows you to adjust the N-Verter’s position and avoid interference with the gear shift, cup holders, etc., in vehicles where the DC socket location causes problems with standard units.

NVD175X – An auxiliary DC socket is provided to allow the use of an additional 12VDC accessory. Be careful that the power requirements of the N-Verter and the additional DC accessory plugged into the auxiliary socket do not exceed the maximum power output of the vehicle’s DC socket.

Operating your N-Verter

1.Plug the N-Verter into your vehicle’s lighter socket. If the socket is too wide and the plug tip of the unit fits loosely, use the slide control on the plug tip to adjust the negative connectors and ensure a snug fit.The green LED will light up when power is present.

Note: Many vehicles remove power from the cigarette lighter outlet when the ignition key is turned off!

2.Plug an AC device into the three-prong AC receptacle and then turn it on. Ensure your

device draws less than the continuous power rating of your N-Verter. To avoid discharging the battery, always remove the N-Verter from the lighter socket when not in use.

WARNING! When using you N-Verter with the vehicle’s engine turned off, the battery is being drained. Be careful to re-start the engine or otherwise recharge the battery periodically to aviod draining the battery too deeply. The internal “low voltage shut-off” of the N-Verter does not guarantee that the remaining power left in the battery is enough to start the vehicle.

WARNING! Hot surface The N-Verter housing may become uncomfortably warm, reaching 65°C (150°F) under extended high power operation. During operation, keep the N-Verter from materials that may be affected by high temperatures.

Modified Sine-Wave Output

THE OUTPUT OF THE N-VERTER IS NON-SINUSOIDAL.This type of output can typically be incompatible with small battery-operated products such as rechargeable flashlights, some rechargeable shavers, and nightlights that plug directly into an AC receptacle to recharge as well as certain battery chargers for battery packs used with power tools. If you wish to use one of these types of items with the N-Verter, monitor its temperature for the first ten minutes to insure excessive heat is not produced.The production of excessive heat indicates the device is not suitable for use with the N-Verter. The overheating does not occur with most devices which use their own AC adapters.The N-Verter is compatible with most of these chargers and AC adapters.
