摘要： The present invention relates to a device for the automatic shut-off of equipment's stand-by power which can switch on or off the power for a set of electric and electronic appliances and can reduce the power consumption in a state of waiting for use. The invention provides a device for the automatic shut-off of equipment's stand-by power which particularly comprises a first relay for switching contacts of the first line, a second relay for switching contacts of the second line, and a power switching controller for detecting whether the light is present and for sequently switching the contact states of the first relay and the second relay depending on the result of the light detection to thereby allow or cut off the commercial alternating current through the first and second lines.

摘要： An active protection circuit for a MOSFET isolated switched power supply system operates to control the switching of the MOSFET isolation switches. A monitoring circuit operates to sense and turn off the isolation switch of the currently active power supply if it senses reverse current flowing through the switch. Simultaneously, a controller receives indication that the active power supply is out of specification, and actively switches the system voltage source to the other power supply. The controller actively ensures that the isolation switch of the out-of-specification power supply remains off until it determines otherwise.

摘要： A backup power-source module that controls a backup power source for supplying power from a battery charged by an AC input to an electronic device when the AC input is cut off. The backup power-source module includes a selection which generates a selection signal for selecting power supplied by a battery when the electronic device is kept in an electrified state until the electronic device is shifted to a power cutoff state and there is no AC input. I.E., the selection signal causes the power supplied by the battery to be selected only when the electronic device is kept in a power cutoff state and there is no AC input.

摘要： A time switch includes a circuit board equipped with a time switch circuit operated by a commercial power source, a battery board to which a back-up battery for supplying a back-up power to the circuit board in case of an interruption of a power supply from the commercial power source is mounted, and a casing in which the circuit board and the battery board are mounted. The battery board is a member separated from the circuit board, or integrally formed with the circuit board by way of an easy-to-break portion having a relatively weak mechanical strength. Thus, the battery board can be detached from the circuit board so that the back-up battery is disposed apart from the circuit board.

摘要： A circuit configuration for a direct-voltage power pack of an electronically controlled switching device, particularly of a small programmable control system, which is externally supplied with voltage, having an arithmetic-logic unit, signal inputs and signal outputs. This circuit has a back-up supplier for the backup supply of the supply voltage and a detector for detecting the input voltage which is not backed up, the detector interacting with the arithmetic-logic unit in such a way that, in response to any voltage failure, the signal inputs are reliably prevented from being read in.

摘要： A power system includes a battery back-up unit (BBU) having back-up battery circuitry which provides battery back-up support for a plurality of power supplies each having a respective power factor correction circuit front-end with a boost stage. The voltages output from the boost stages of the power supplies are monitored and compared with respective reference threshold voltages to derive a signal which is used to bring battery back-up power on-line when a monitored voltage falls below a threshold voltage, which may be indicative of a loss of AC mains input voltage. AC mains input voltage is also monitored to detect a restoration and disconnect the battery back-up power. In the event that battery back-up is brought on-line due to a faulty power supply rather than a loss of AC mains input voltage, the faulty power supply can be masked and reported for repair.

摘要： In a semiconductor integrated circuit device and a contactless electronic device, an AC voltage is applied to first and second input terminals. A rectification transistor having a drain (or collector) connected to a second input terminal and gate (or base) and drain (or collector) connected to each other through a first resistor supplies a rectified current between the first and second input terminals. A first voltage detector means produces a control voltage so that the rectified voltage obtained on the source (or emitter) side of the first rectification transistor is equal to a predetermined reference voltage. The first voltage controlled current source can produce current in accordance with the control voltage and supply the current to the first resistor. Such a power supply circuit is mounted in the contactless electronic device.

摘要： The supply of power from a battery to a load is controlled by the charging current output status of a solar cell, such that when the solar cell receives light, the load is cut off; and once the solar cell no longer receives light, the battery is charged to a preset saturation level and the solar cell no longer supplies charging current to the battery, or the charging current falls short of a predetermined level, the battery will revert to an output mode with suspension of the charging function.
