| Title: |
Automatic Transfer Switch |
| Abstract: |
Automatic transfer switch for switching an electrical load between two
power sources. In one example, the automatic transfer switch includes
four latching relays and an electronic controller. A first power source
line connection is connected to an electrical load line connection via a
first latching relay. A first power source neutral connection is
connected to an electrical load neutral connection via a second latching
relay. A second power source line connection is connected to the
electrical load line connection via a third latching relay. A second
power source neutral connection is connected to the electrical load
neutral connection via a fourth latching relay. The electronic controller
connects the second power source to the electrical load when a voltage of
the first power source is less than a first threshold, and connects the
first power source to the electrical load when the voltage is greater
than a second threshold.
