摘要： An apparatus in an electronic control system allows two or three wire operation. A power supply can supply power to the enclosed circuitry in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two and three wire installations. Both zero cross detectors are monitored and are used to automatically configure the electronic control. Over voltage circuitry senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuitry senses when the current through the MOSFETs has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuitry is employed to keep the protection circuitry in effect even after a fault condition has cleared. Lockout circuitry is used to prevent one protection circuit from tripping after the other circuit has already tripped from a fault condition. The protection circuitry output is desirably configured such that it can bypass and override the normal turn on and turn off impedance and act virtually directly on the gates of the MOSFETs. Preferably, the system has a high efficiency switching type power supply in parallel with a low frequency controllably conductive device.

摘要： Power distribution systems that have a limited peak power capability or a high source impedance, such as site supply generators, are often susceptible to abnormal operation in response to the current drawn at power up from the loads connected to the power distribution system. The present invention provides a method of configuring a lighting control system to power up a plurality of the lighting loads in sequence to reduce stress on the power distribution system. The lighting control system includes a plurality of load control devices for controlling the electrical loads. The method comprising the steps of enabling a startup-delay mode in the load control devices, and determining a startup sequence having a plurality of event times for the electrical loads to turn on after the power distribution system has stabilized. A graphical user interface may be used to create a database defining the operation of the startup sequence.

摘要： A power supply with a capacitor providing an output voltage. A switch is connected between a voltage source and the capacitor. A control terminal of the switch has a switching threshold. The switch conducts a charging current from the voltage source into the capacitor. A control circuit controls the switch on when the voltage source is below a predetermined level and off when the voltage source is above the level. A control voltage supply circuit provides a control supply voltage. A control terminal voltage for the switch derived from the control supply voltage with a magnitude in excess of the switching threshold drives the switch on in a saturated region of operation.

摘要： A linear slide selector switch for multiple channels for selecting between several switch positions. Specifically, there is a housing having a hinged door with a latch lock, the door rotates to a closed position and is held in a closed position by the latch lock. The housing also contains a slide and a printed circuit board. The printed circuit board has rows of contacts. A contactor is mounted to the slide. As the slide is moved linearly, electrical connections are made and broken on the printed circuit board.
