Motor speeds of 60, 30, 15 and 5 seconds full range travel time are available depending on the transformer size. Available motor speeds can be selected above. All motors are 120VAC 50/60 Hz rated. Motor speeds are shown are for 60 Hz operation. Motors will run 20% slower when operated on 50 Hz. A separate 120VAC 50/60 Hz source is required if transformer is used on a 400 Hz source.
