SLEEP is a new function available in the ICON3000 electric actuator which reduces power
consumption from the electronics when the actuator is not moving.
This function is useful when the actuator is powered via battery and solar panel, and if few
valve travel events are expected. In these applications, electrical power is absorbed from
the battery when the motor is running, and when the motor is off the solar panels recharge
the battery and power the actuator’s electronics.
Since the run time of the motor is a small percentage of the total time that the actuator
will spend in the eld, the energy necessary to power the electronics during the motor’s
rest phase is a high percentage of the total energy needed. Reducing energy requirements
when the motor is OFF allows a smaller solar panel to be used.
The gure below demonstrates the utility of the SLEEP function.
