Abstract

A power transfer system includes four relays for switching power from a primary power supply to an auxiliary power supply having a starter motor and a kill switch. A first relay couples the primary power supply to the load. A second relay is responsive to the failure of the primary power supply and activates the starter motor and deactivates the kill switch. A third relay is responsive to power supplied by the auxiliary power supply and couples the auxiliary power supply to the load. A fourth relay is responsive to power supplied by the auxiliary power supply and decouples the primary power supply from the load and deactivates the starter. An optional time delay relay is provided for delaying the activation of the starter motor upon the loss of power supplied by the primary power supply.

Claims

1. A power transfer system for connecting a load normally connected across a primary power supply across an auxiliary power supply having a start means and a stop means upon a failure of the primary power supply comprising:

a first two pole--single throw relay for coupling the primary power supply to the load;

a first two pole--two throw relay responsive to the failure of the primary power supply, said first two pole--two throw relay for activating the start means and deactivating the stop means;

a second two pole--single throw relay responsive to power supplied by the auxiliary power supply, said second two pole--single throw relay for coupling the auxiliary power supply to the load;

a second double pole--double throw relay responsive to power supplied by the auxiliary power supply, said second double pole--double throw for decoupling the primary power supply from the load and deactivating the start means;

a time delay relay responsive to the failure of the primary power supply, said time delay relay for activating the start means after a predetermined time delay period from the time of failure of a primary power supply.

2. The power transfer system of claim 1, further comprising a trickle charger coupled to the primary power supply, said trickle charger for charging a starter battery coupled to the start means.

3. The power transfer system of claim 1 further comprising a switch interposed between the primary power supply and the load, said switch for decoupling the primary power supply from the load.

4. A power transfer system for connecting a load normally connected across a primary power supply across an auxiliary power supply having a start means and a stop means upon a failure of the primary power supply, the power transfer system comprising:

a first double pole--single throw relay for coupling the primary power supply to the load;

a first double pole--single throw relay responsive to the failure of the primary power supply, said first double pole--single throw relay for activating the start means and deactivating the stop means;

a second double pole--single throw relay responsive to power supplied by the auxiliary power supply, said second double pole--single throw relay for coupling the auxiliary power supply to the load;

a second double pole--double throw relay responsive to power supplied by the auxiliary power supply, said second double pole--double throw relay for decoupling the primary power supply from the load and deactivating the start means;

a time delay relay responsive to the failure of the primary power supply, said time delay relay for activating the start means;

a trickle charger coupled to the primary power supply, said trickle charger for charging a starter battery coupled to the start means; and

a switch interposed between the primary power supply and the load, said switch for decoupling the primary power supply from the load.
