Note: Specications are subject to change without notice. Specications are warranted over an ambient temperature range of 25°± 5° C. Unless otherwise noted, specications are per phase for a sinewave with a resistive
load and apply after a 30 minute warm-up period. For three phase congurations, all specications are for L-N. Phase angle specications are valid under balanced load conditions only.
