inverter. The series provides big power in small pack-
ages. High efficiency designs make each model ideal for all mobile
environments where space is at a premium.
Inverter is the proper term for any device that turns DC (direct
current) into AC (alternating current). The inverter takes
12 volts DC from your battery and converts it to 115 volts AC to run
appliances. Just like utility power, the frequency is held constant at
60 Hertz, and the output voltage is regulated between 110 and 120
volts true RMS, despite changes in load and battery voltage.
The energy delivered by the inverter comes from the battery which
powers it. And that energy was put into your battery by your
battery charger, which might be a vehicle alternator or an electronic
power supply.
The most appropriate use of an inverter system is for light, long-
term loads, such as TVs, VCRs and small computers, or for heavy,
short-term loads such as vacuum cleaners, microwave ovens and
hair dryers.
Heavy, long-term loads like electric heaters and air conditioners
require a great deal of energy. While they wonÕt harm your inverter,
they would need an extremely large battery to run continuously
overnight, and then a very heavy charger to recharge that battery
the following day.
There really arenÕt a lot of doÕs and donÕts to remember. Your
inverter is designed to protect itself and your battery.
NOTE: While the inverter does not mistreat your
appliances, it cannot protect them. A light bulb can burn out, or an
appliance can fail, just as it might when plugged into utility power.
Please take a few moments to read this owners manual. It contains
important safety information as well as practical application tips.
