For transformer loads, the thyristor power unit operates in burst-firing mode
with a cut-back (retarded) phase-angle for the first half-wave. The factory set-
ting is an angle α = 90°. This value can be altered on the front panel over a
range α = 0 — 90°.

We recommend that this setting is not changed!
