2. Specifications
Specifications shown are valid over an ambient temperature range of 25 5 C and apply after a
30 minute warm-up time. Unless otherwise noted, all specifications are per phase for sine wave
output into a resistive load. For three phase configurations or mode of operation, all
specifications are for Line to Neutral (L-N) and phase angle specifications are valid under
balanced load conditions only.
Specifications for Ls models are identical to those for the Lx except where noted.

configurations, currents are per chassis.

Note that operation below 208V L-L AC input is available with the following derating considerations:
1) If operating at less than a 5000 VA output power there will be no affect on the output.
2) If operating in 3-phase mode, with a full-scale output voltage and a frequency less than three times the line
frequency, the voltage distortion may exceed specification between 5500 and 6000 VA output.
3) If operating in 1-phase mode above 5000 VA, above 85% of full-scale output voltage and an output frequency
less than three times the line frequency, the voltage distortion may exceed specification and the output may fault
with a crest factor load more than 2.
In most applications, these conditions are not likely to exits. At AC input voltages of 208 V or higher, the 6000Lx/Ls
meets specifications under all conditions.
