Champion Global Power Equipment 2000W Inverter
The world of inverter generators (commonly referred to as inverters) is full of facts and fi gures that are often confusing and
sometimes misleading. This paper will focus on four often misunderstood characteristics:
What is a True Sine Wave?
A true sine wave (TSW) describes the perfect, smooth waveform of electrical output. Alternating current (AC) produced by a TSW
inverter, such as a Champion 2000W Inverter, has a smooth waveform. This differs from the modifi ed sine wave (MSW) of square
wave and modifi ed square wave inverters.
The waveform of these types of inverters
is a rough, stepped, digital approximation
of a TSW. See the graph to the left.
MSW power can cause problems with
certain electrical equipment, such as
variable speed motors, drills, sensitive
electronics, power supplies, transformers,
battery chargers and dimmer switches.
Consult the equipment manufacturer
before using MSW power sources.
Devices that depend on TSW output for
proper operation (i.e. sensitive to voltage
peaks or zero crossings) could be damaged or experience problems with MSW output. Radio operators may experience radio
frequency noise from these power sources. Inverters with MSW output may produce a hum or buzz in the audio of TV’s, radios and
satellite systems. These applications should be powered by TSW sources.
Noise Levels Explained
Noise level (technically, sound pressure level) is measured in decibels (dB) which
is a logarithmic unit. The noise level of a device decreases over distance. A
noise source will “sound” louder from 1 meter away than the same source would
“sound” from 7 meters away. As a rule of thumb, the noise level decreases 6 dB
when the distance from the source is doubled. Many manufacturers measure the
noise level of their inverters from a distance of 7 meters (about 23 feet).
Noise level measurements can be diffi cult to accurately reproduce. Sound
refl ecting and sound absorbing surfaces (ground surface, walls, vegetation), as well as ambient noise (wind, cars) are two factors
that may infl uence dB measurements.
The Champion 2000W inverter noise level (shown in Table 1) is measured under the following conditions following conditions:
• Distance of 7 meters (23 feet) from inverter
• Inverter placed on concrete surface
• 30.4 meters (100 feet) from refl ective surfaces (walls)
• Ambient noise level 45 dB
