7 Operating 115 Volt AC
Products and Equipment
7.1 General Information
The PORTAWATTZ 400 is capable of powering most 115-Volt AC
products that use 400 Watts or less. Its AC output waveform, called
“modified-sine wave” is designed to function similarly to the sine
wave shape of utility power. Most AC products rated for 400 Watts or
less will operate normally with the PORTAWATTZ 400.
The power, or “wattage”, rating of AC products is the average power
they use. When many AC products are first switched on, they initially
consume more power than their power rating. TVs, monitors, and
electric motors are examples of products that have high “surge”
requirements at start up. Although the PORTAWATTZ 400 can
supply momentary surge power as high as 800 Watts, occasionally
some products rated less than 400 Watts may exceed its surge
capabilities and trigger its safety overload shutdown feature. If this
problem occurs when attempting to operate several AC products at
the same time, try first switching on the inverter with all AC products
switched off, then one by one switch each on, starting with the high
surge product first.
Although the PORTAWATTZ 400 can also be powered from a
cigarette lighter or 12-Volt outlet in a vehicle, these outlets are only
designed to safely supply a maximum of 150 Watts.
7.2 Interference with Electronic
Equipment
Generally, most AC products operate with the PORTAWATTZ 400
just as they would with household AC power. Below is information
concerning two possible exceptions.
Buzzing Sound in Audio Systems and Radios
Some inexpensive stereo systems, “boom boxes”, and AM-FM radios
have inadequate internal power supply filtering and “buzz” slightly
when powered by the PORTAWATTZ 400. Generally, the only
solution is an audio product with a higher quality filter.
