Abstract: Multi-time delay power controller apparatus for providing time delayed power-up and power-down for associated electrical equipment, such as computer systems, comprises a power stage configured for connecting to a conventional power outlet, a D.C. power supply connected to an internal D.C. voltage bus, an output stage having a plurality of time delayed outputs and a plurality of time delay turn-on timing stages connected in electrical series with one another between the D.C. bus and ground. Each such stage comprises an R-C circuit and a type 555 integrated circuit which together function as a timer. Included in each stage is a control relay. 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. The control relays, which provide voltage to the time delayed output stages are energized, in sequence, when each stage times out. Timed delay turn-off means are provided for sequentially removing the voltages to the outputs in the reverse order in which voltage is applied by operation of the control relays. The time delay turn-off means include relays through which the time delay turn-on relays are energized and which cause deenergizing of the control relays in the turn-off sequence.

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. A logic control timing circuit enables the circuit breaker to latch on when it is manually turned on and while the operating voltage is stabilizing in the line voltage monitor. The power controller apparatus may include at least one switched power outlet connected for receiving operating voltage from the circuit breaker and includes a switch for enabling the switched power outlet to be selectively turned on and off while the circuit breaker is tripped on.

Abstract: Multi-time delay power controller apparatus for providing time-delayed power or control signals to associated electrical equipment, such as computers and disc drives, comprises a power stage configured for connecting to a conventional power outlet, a D.C. power supply connected to an interval D.C. voltage bus, an output stage having a plurality of time delayed outputs and a plurality of time delay timing stages connected in electrical series to one another between the D.C. voltage bus and ground. Each such timing stage includes a timing means, and a normally open control relay. Coils of odd numbered timing stages are connected to ground and of even numbered stages to the D.C. voltage bus. The timing stages are connected so that the timing out of one stage starts the timing of the next-in-sequence stage, timing of the first-in-sequence timing stage being started when the apparatus is turned on. The control relays are actuated when a stage times out, thereby causing a time delayed control signal to be provided to the output stages. When time delayed power outputs are provided, the time delayed control signal energizes a normally open power relay which connects the associated power output to the power stage.
