As of v0.200.231 (and newer) weapons seem to draw their full charging power continuously and never revert to the lower resting state power draw. Firing the weapons works fine but does not increase power draw at all. Unlike weapons, salvage arrays do correctly use the charging and resting power draw.
Dev builds v0.200.228 and earlier do not have this problem.
