1.Supply voltage: ac, single phase, 230v, 50hz. 2.Power consumption: 20 watts. 3.Stroke: factory set at 900, 1600 or 2700. (field adjustment in steps of 30 is possible). 4.Auxiliary switch (optional): 2.5a, 250v, 50hz, no or nc. (operated at only one fixed point). 5.Feedback potentiometer: 135Ω standard matched to stroke angle of either 900, 1600 or 2700. (the maximum permitted power dissipation is 1w for 900, 1.5w for 1600, & 2w for 2700). 6.Torque-speed capabilities: total gear ratio is adjusted at factory to obtain the following combination of torque and speed.
