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.
