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 @ 0.8 power factor,
1570 VA@ .7 pf, or an incredible 2200 VA @ 0.5 pf.; and our 2000
watt inverter could be rated at 2500 VA @ 0.8 pf., 2857 VA @ 0.7
pf, or an incredible 4000 VA @ 0.5 pf. It is confusing to specify a
product in VA, because the power factor must also be specified.
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 which
protect the inverter from any overload condition.
XP-600, XP-1100 and XP-2000
These inverters can supply twice their rated output power for 3
seconds, in order to start motors or supply in-rush currents to
electronic loads. If output power is exceeded for greater than 3
seconds, output voltage is reduced to a level which 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 Exeltech’s XP-Series inverters can output their full
rated power continuously at 30 C (86 F). The inverter is derated

capacity at 40 C, 60% at 50 C . . . Etc. .
