Abstract
An actuator includes a solenoid including a coil and a plunger, a switch circuit coupled to the coil, and a control circuit coupled to the switch circuit. The control circuit is configured to receive a feedback signal representative of a plunger position. The control circuit is also configured to provide power to the solenoid via the switch circuit and reduce power to the solenoid via the switch circuit in response to the feedback signal being representative of the plunger being in a full travel position.
Claims21
An actuator comprising:
- a solenoid comprising a coil and a plunger;
- a switch circuit coupled to the coil;
- and
- a control circuit coupled to the switch circuit, where in the control circuit is configured to receive a feedback signal representative of a plunger position, the control circuit being configured to provide power to the solenoid via the switch circuit and reduce the power to the solenoid via the switch circuit in response to the feedback signal being representative of the plunger being in a full travel position.
A solenoid system, comprising:
- an alternating current input configured to receive an alternating current input power within a voltage range from 24V to 480V;
- a solenoid comprising a coil and a plunger;
- a switch circuit coupled to the coil;
- and
- a control circuit coupled to the switch circuit, wherein the control circuit is configured to receive the alternating current input power and provide solenoid power to the solenoid via the switch circuit.
A heating, ventilation, or air conditioning (HVAC) actuator, the actuator comprising:
- a solenoid comprising a coil and a plunger, wherein the coil comprises an aluminum conductor;
- a switch circuit coupled to the coil;
- and
- a control circuit coupled to the switch circuit, where in the control circuit is configured to receive a feedback signal, the control circuit being configured to provide power to the solenoid via the switch circuit and reduce the power to the solenoid via the switch circuit in response to the feedback signal to reduce power consumed after in-rush current is received.
