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 2253i models are identical to those for the 2253iX except where noted.
