Electronic Damper ActuatorsTBT3060 ATBT3080 Afor dampers up to 45 square feetor 4 square metersbased upon 4 in.lb. per square footDescriptionThe TBT3060 A and TBT3080 A are digital actuators that operateon 24 volt AC nominal power supply. Both models deliver a minimumof 180 in.lb. or 20 Nm. torque at rated voltage. The direction of rotationis reversible and the angle of rotation may be mechanically limited.These actuators are equipped with the patented Enerdrive System,The Electronic Spring* which is an emergency operating device thatpowers the actuator at full rated torque to its safety position. TheEnerdrive System may be used as the means of closure in 2 wire/2position installations. The TBT3080 A is also equipped with 2mechanical auxiliary switches.Model SelectionTBT3060 ATBT3080 ADigital Actuator with the Enerdrive SystemDigital Actuator with Enerdrive & Auxiliary SwitchesActuator SpecificationsPower SupplyMaximum Power ConsumptionElectrical ConnectionsInlet BushingControl SignalTorque24VAC +/-10% or 30VDC +/-10%24VA at 26VAC Peak at Start-up8VA at 26VAC Operating at Full Load18 AWG Minimum, 25 ft. or 7.6 m.

Electronic Damper ActuatorsTBT3060 ATBT3080 ADimensionalSchematicA data sheet with more detailed dimensionalinformation and part nomenclature is availableupon request.Wiring SchematicsIt is recommended that all NEPTRONIC products be wired to a separate transformer and that thattransformer shall service only NEPTRONIC products. This precaution will prevent interference with,and/or possible damage to, incompatible equipment of other manufacture. CAUTION! Whenmultiple actuators are wired on a single transformer, polarity must be respected! Long wiring runscreate voltage drops which may affect the actuator's performance.ADFS DIR/REVDIR/REVTBT3060 ATBT3080 A2 Position ControlDrive CWEnerdrive CCWFS DIR/REVDIR/REVTBT3060 ATBT3080 A2 Position ControlDrive CCWEnerdrive CWDIM.BINCHESCCENTIMETERSA 1.333.38U CLOSED 80-90U CLOSED 0-80U COMMONL CLOSED 0-10L CLOSED 10-90L COMMONTBT3080 AONLYU CLOSED 80-90U CLOSED 0-80U COMMONL CLOSED 0-10L CLOSED 10-90L COMMONTBT3080 AONLYB 5.2013.21C 9.1323.19D 3.398.61DIP SWITCH POSITIONSFS DIR/REVDIR/REVDRIVE CW22-26VAC28-32VDCCOMMONTBT3060 ATBT3080 A3 Point Floating ControlEnerdrive CCWFS DIR/REVDIR/REVDRIVE CCW22-26VAC28-32VDCCOMMONTBT3060 ATBT3080 A3 Point Floating ControlEnerdrive CWThe dip switches are factory set in the"OFF" position.Dip Switch #1 controls the direction ofrotation.
