Abstract: A DC/AC adapter assembly has a DC/AC adapter and a cable. The cable transmits a power-overloading signal to the DC/AC adapter indicating whether power-overloading is occurring in the cable. The DC/AC adapter includes a controller circuit for controlling and adjusting an output alternating current of the DC/AC adapter based on the power-overloading signal to reduce power-overloading occurring in the cable.

Abstract: A cable clamp has a body, at least one front binding hole, at least one rear binding hole, multiple front connecting elements, multiple rear connecting elements, a first lateral connecting element and a second lateral connecting element. The front and the rear connecting elements are formed on the body, and the rear connecting elements correspond respectively to the front connecting elements. The first lateral and the second lateral connecting elements are formed on the body, and the second lateral connecting element corresponds to the first lateral connecting element. Each cable clamp is capable of attaching to another cable clamp rather with connecting the front connecting element of the cable clamp to the rear connecting element of another cable clamp or with connecting the second lateral connecting element of the cable clamp to the first lateral connecting element of another cable clamp.

Abstract: The power saving uninterruptible power supply (UPS) has a first and second switches, an energy spared switch, a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. When the utility power is stable, the first and second switches are connected together to supply the utility power to a load. At the time, the energy spared switch is physically disconnected with the utility power and the transformer and the AVR. Therefore, the transformer and AVR do not consume more energy of the utility power and the transforming efficiency of the UPS is increased.

Abstract: The power saving uninterruptible power supply (UPS) has a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. The transformer has a primary side and a secondary side. The primary side is coupled to an alternating current (AC) power source. An AC input terminal of the AVR is coupled to the secondary side of the transformer to acquire an inducted AC power source to regulate the inducted AC power source to output to a load. The charger-and-inverter is coupled to the secondary side of the transformer to acquire a recharged power source to convert to a recharged current. The normal mode determination unit is coupled to the AC power source and the battery to detect a power supply status of the AC power source and battery capacity, so as to further determine whether current operation is normal.

Abstract: An auxiliary device for a connector has a body, a wire unit and plug. The wire unit is mounted securely in the body and extends out of the body from a first end of the body. The plug is formed on a second end of the body and is perpendicular to the wire unit. Therefore, the position of the wire unit is fixed when the plug is inserted into a socket.

Abstract: A voltage regulating circuit has a first switch, a transformer and a second switch. The first switch has an input node, a first node and a second node. The transformer is connected to the switches has a first coil and a second coil. The first coil and the second coil respectively have an end, and the second coil is connected to the first coil in series at a node. The node between the first and second coils is connected to the second node of the first switch. The second switch is connected to the transformer and has a first node, a second node and an output node. The first node is connected to the end of the first coil. The second node is connected to the first node of the first switch. The transformer will not heat up when the transformer needs not to be used.
