SmartAC 425W Power Inverter by Wagan Tech
(Pure sine wave)
This modified sine wave has a root mean square (RMS) voltage of 115 volts. Most
ordinary AC voltmeters are calibrated to read "average" voltage and assume that
the AC waveform will be a pure sine wave. These meters will not correctly read
MSW voltage, and will display about 20 to 30 volts too low. Any multi-meter
identified as "TRUE RMS" will accurately read MSW correctly.

PRODUCT USAGE

Maximum Power from Vehicle Accessory Sockets
Most vehicle accessory sockets that are controlled through a vehicle's ignition
switch are fused at 15 amps. This limits inverter output to approximately 180
watts.
To Power 425 Watt Appliances: For temporary use, connect a battery clip
adapter cord to the inverter and follow the procedure located under the
"Connecting the Inverter" section.
There is no danger in leaving the inverter directly wired to the battery if the
inverter is turned off after each use. The inverter will shut off when the vehicle's
battery level drops down to 9.5 volts to protect the battery from draining
completely.

Determining Maximum Appliance Wattage

… Do not exceed the 425 watt maximum AC load or the inverter will shut
down.
