PUMP CONTROL SYSTEM WITH ISOLATED AC VOLTAGE DETECTOR |
| 摘要 |
A pump and a method of operating the pump at a duty-cycle based on the input voltage of the power source energizing the pump. The pump includes at least a first opto-coupler electrically coupled, to the power source. The method includes detecting at least a first opto-coupler state transition; determining a zero-crossing of the input voltage; determining an elapsed time between the zero-crossing and the first opto-coupler state transition; and operating the pump by energizing a power switch at a duty-cycle based on the elapsed time. |

1. A method of operating a pump, the method comprising:
detecting at least a first opto-coupler state transition of a first opto-coupler electrically coupled to a power source coupled to the pump; determining a zero-crossing of an input voltage of the power source; determining an elapsed time between the zero-crossing and the first opto-coupler state transition; and operating the pump by energizing a power-switch at a duty-cycle based on the elapsed time. |
