specify these products is in Watts (W), which is power the inverter
can actually deliver. If Exeltech inverters were specified in VA, Our
1100 Watt inverter could be rated at 1375 VA at .8 power factor,
1570 VA at .7 pf, or an incredible 2200 VA at .5 pf. It is confusing to
specify a product in VA because the power factor must also be
specified. Exeltech's XP-Series inverters can output their full rated
o
o
power continuously up to 30 C (86 F).
The inverter can maintain a spectrally pure output with any load due
to a specially designed non-linear control loop in the primary DC-to
-DC converter. This circuitry is one of three circuits that protect the
inverter from any overload condition.
These inverters
are capable of exceeding their rated power by 10%
for a limited time. The inverter's capability at this level is primarily
dependant upon temperature. If output power is exceeded, output
voltage is reduced to a level that will provide the inverter's rated
power to the load by clipping tops of the waveform. The inverter can
operate safely in this mode indefinitely. Should the overload condition
clear, the inverter will again provide the cleanest sine-wave in the
industry.
