DC to AC Power Inverter User’s Guide
150W/200W/350W/500W/1000W
Thank you for purchasing the WELLSEE power inverter. The WELLSEE power inverter is an ultra compact and highly portable power inerter from WELLSEE, the leader in the field or high frequency inverter design. Form the 12-votlet in your car or boat. The WELLSEE POWER will reliably Power a wide variety of household AC products and mobile phone charges. The WELLSEE POWER is designed to provide years of trouble free operation and includes automatic safely monitoring circuitry safety to protect it, and your battery. From inadvertent overload conditions.
Read this guide before installing or using the WELLSEE Power it for future reference.
1. Placement Guidelines
For optimum operation, the WELLSEE inverter should be placed on a flat surface such as the floor or a car, THE LOCATION SHOULD BE:
■Dry. Do not expose to water drip or spray
■Cool. Operate only in ambient temperatures between
32。F(0。) and 104。F(40。)keep away from heating vents
■Well ventilated. Allow at lease 2 inches (5 cm) clearance above and on all sides of the WELLSEE inverter for proper cooling
2.Inverter operation
■Turn the WELLSEE inverter ON/OFF switch ON.
■Connect the electric cord with the product to the correct terminal , for example , the red wire goes to the positive terminal . Except for the inverter which power is below 120W, because it only has the socket for lighting cigarette.
■Should a defective battery charging system cause the battery voltage to rise to dangerously high levels, the WELLSEE inverter automatically shuts down. The red FAULT light will turn on.
3. CAUTION!
Although the WELLSEE inverter incorporates protection against over-voltage, it may still be damaged if the input voltage exceeds 16 volts.
■In the event of an overload, low battery or overheating, the WELLSEE inverter will automatically shut down.
Interference with Electronics Equipment
Generally, most AC products operate with the WELLSEE inverter just as they would with household AC power. Below is information concerning two possible exceptions Buzzing Sound in Audio Systems. Some inexpensive stereo systems and“boom boses” have invedequate internal power supply filtering and “buzz” slightly when powered by the WELLSEE inverter. Generally , the only solution is an audio systems with a higher quality filter.
Television interference
The WELLSEE inverter is shielded to minimize interference with TV signals. However, with weak TV signals interference may be visible in the form of lines scrolling across the screen. The following should minimize or eliminate the problem.
■Use an extension cord to increase the distance between the WELLSEE inverter and the TV antenna and cables.
■Adjust the orientation of the WELLSEE inverter, television, antenna and cables.
■Maximize TV signal strength by using a better antenna and use shielded antenna cable where possible.
■Try a different TV Different models of televisions vary considerably in their susceptibility to inter ference .
Battery Operating Time
When using the WELLSEE inverter. operating time will vary depending on the charge level of the battery. Its capacity and the power level drawn by the particular AC load . With a typical vehicle battery and a 50-watt load(such as a portable stereo/CD player). an operating time of 5-6hours or more can be expected.
When using a vehicle battery as a power source, it is strongly recommended to start the vehicle every hour or two to recharge the batter before its capacity drop that occurs during starting may trigger the WELLSEE inverter’s low voltage shutdown feature.
Because the WELLSEE inverter draws less than 0.15 amps with the ON/OFF switch in the ON position and with no AC products connected, it has minimal impact on battery operating times.
4. Trouble shooting
■Problem: AC product will not operate, no inverter lights are on
Possible cause: suggested Remedy
Poor contact with lighter Press plug firmly into socket, clean
Socket or 12-volt outlet plug or socket if necessary
Lighter socket or 12-volt Turn key to accessory position
Outlet may require ignition
To be switched on.
Cigarette lighter or 12-volt Check vehicle fuses and replace blown
Outlet fuse is blown fuse with correct value
Inverter has been connected Probable inverter damage has occurred.
With reveres Dc input polarity Have unit repaired.
■Problem: Measured inverter output is too low.
Possible cause: suggested Remedy
Standard “average leading” Inverter’s
AC voltmeter used to output
measure output voltage. requires “true RMS”
resulting in an apparent voltmeter, for occur are
reading 5 to 15 volts too low. measurement
Battery voltage is too low. Recharge battery
■Problem: Battery run time is less than expected.
Possible cause: suggested Remedy
AC product power Use a larger battery to make up
Consumption is higher for increased power requirement
Than rated
Battery is old or defective Replace battery
Battery is not being Have vehicle electrical systems
Properly charged checked by a qualified technician
