Abstract: A dual-input, automatic-switching power supply comprises a primary power input, a secondary power input, and a power output. Included are first and second DPST mechanical relays and a third DPDT mechanical relay. A first relay input is connected to the primary power input and a corresponding first relay output is connected to a third relay input. A second relay input is connected to the secondary power input and a corresponding second relay output is connected to a different third relay input. The third relay output is connected to the power output. The relays in combination provide a relay moving contact gap spacing, source to source, of at least three millimeters. A first under voltage control module maintains the first and third relays in states causing the primary power input to be connected to the power output as long as voltage from the primary power input remains above a preestablished primary voltage dropout level.

Abstract: An electronic switched-output controller apparatus comprises a plurality of relays for providing a plurality of controlled switched outputs, the relays being selected from the group consisting of power relays, signal switching relays, dry contact closing relays and combinations thereof, each of the relays having a corresponding relay operating coil. A power section is configured for receiving AC line power and for providing internal operating DC voltage and is connected for providing line AC power to any power relays and thereby to corresponding outputs when the corresponding power relay coils are actuated, and for providing DC voltage to any signal switching relays and thereby to corresponding outputs when the corresponding switching signal relay coils are activated.

Abstract: A one time programmable (OTP) electronic switched-output controller apparatus comprises a plurality of switched-output relays which may be power relays, signal voltage relays, dry switching relays or any combination thereof. A power section receives AC line power and provides at least one internal operating DC voltage and provides line AC power to any power relays and to the related power outputs when the relay are actuated. An A-D converter provides DC voltage for internal operation and to any DC voltage relays. A one time programmable microcontroller, which has outputs connected to the relay coils, is programmed before installation in the switched-output controller apparatus to cause actuation of the relay coils in accordance with a preestablished operating protocol. The apparatus is shown connected for receiving RS232 signals and has an internal modem for receiving external signals over a telephone line. A relay enables switching between the RS232 and modem inputs.

Abstract: A power controller comprises a manually-on circuit breaker having an electrically-actuatable trip coil which enables the circuit breaker to be tripped-off electrically. The circuit breaker is connected to a voltage source and provides operating voltage to a power outlet. A line voltage monitor provides a voltage indication to a logic control circuit when operating voltage moves outside a predetermined range established by setting upper and lower operating voltage limits. In response to receiving such a voltage indication, the logic control circuit deenergizes a relay, thereby connecting a charged capacitor to the tripping coil of the circuit breaker to cause the breaker to be tripped-off even when the voltage to the circuit breaker drops to zero volts. Other signals provided to the control logic circuit also cause the deenergizing of the relay controlling the circuit breaker tripping capacitor.

The energizing coils of the relays in odd numbered stages are connected to ground and of even numbered stages to the D.C. bus. The timing stages are connected so that the timing out of one stage starts the timing of the next-in-sequence stage, the timing of the first-in-sequence stage being started when the apparatus is turned on.
