Power supply equipment includes an adapter which converts power from a power source to DC power for powering an electronic device. The power supply equipment includes circuitry which produces a data signal for use by the electronic device to control power drawn by the electronic device. A cable extends from the adapter. The power supply equipment further includes a tip which has an input side and an output side. The input side of the tip is detachable mateable to the cable. The output side of the tip is detachably mateable to the electronic device. The tip output side has a shape and size dependent on the shape and size of a power input opening of the electronic device. The tip provides the data signal, as well as the DC power, to the electronic device. Different tips may be used to provide appropriate data signals to different electronic devices.

As paths for a current flowing through a conductor, a first current path through which a current flows from a first conductive portion to a second conductive portion, and a second current path through which a current flows from a third conductive portion to the second conductive portion are provided. Each of the first conductive portion, the second conductive portion, and the third conductive portion has a plate shape, a point P1 is located on a plate surface of the first conductive portion, and a point P2 is located on a plate surface of the second conductive portion. A current detecting circuit detects a value related to a potential difference between the points P1 and P2, and outputs a voltage value corresponding to a values of a current flowing through each of the first current path and the second current path.

A control circuit applied to a lifting platform controls a motor to adjust the height of a platform. The control circuit includes an AC/DC conversion circuit, a DC/DC conversion circuit, a detection unit, and a control unit. The detection unit detects an output end of the AC/DC conversion circuit and provides a detection signal. The control unit provides a PWM signal according to the detection signal to control the DC/DC conversion circuit so that the DC/DC conversion circuit converts a DC voltage to an output voltage. When the control unit realizes that the DC voltage or a DC power provided by the AC/DC conversion circuit is less than a power supply threshold according to the detection signal, the control unit decreases a duty cycle of the PWM signal to maintain the DC voltage or the DC power to be greater than or equal to the power supply threshold.
