Note: 66% setting and 100% setting require voltage supply minimum values as follows:
-
Supply voltage needs to be min 24vDC for battery fail-safe models.
-
When operating above 20VDC and 66% power, Duty cycle is reduced to 50% - 25% maximum.
At these levels, the electronics produce more heat which must be dissipated (depending on
environmental temperature)
Note: Digital potentiometer functionality is disabled for supply voltages below 18VDC, so the
actuator position will not be retained on power-loss, on power-up the actuator will need to be
re-zeroed every time. For the battery fail-safe model, upon loss of power, the actuator will
move to the defined fail position and track the movement.
Battery fail-safe models will not operate below 18vDC
Operating torque is 100%. These torque values are for valve seating.
