Example

[0020] See Figures 1 to 2As shown, a dual-tone dimming power supply applicable to both two-wire and three-wire circuits includes a U-shaped base shell 1 and a cover 2 disposed on top of the base shell. A dual-tone dimming circuit board 3 is fixed inside the base shell. Input terminals 4 and output terminals 5 are fixed at both ends of the base shell, and both the input and output terminals are connected to the dual-tone dimming circuit board. In this embodiment, the output voltage of the dual-tone dimming circuit board is 24V. The dual-tone dimming circuit board is a conventional structure in the prior art, and is only used in a simple application, so it is not described in detail. Both the base shell and the cover are metal structures, specifically aluminum profiles or stainless steel structures.

[0021] Meanwhile, the input terminal 4 includes a positive terminal 41, a negative terminal 42, and a ground terminal 43; and the output terminal 5 includes a positive output terminal 51, a first negative output terminal 52, and a second negative output terminal 53, with the positive output terminal positioned between the first and second negative output terminals. This structure enables three-wire or two-wire input and also supports dual-tone dimming output, improving ease of use and stability / reliability.

[0022] Furthermore, in practical applications, both ends of the base shell are provided with wire clamp supports 6, and the top surface of the wire clamp supports is provided with several U-shaped grooves 7; the top surface of the wire clamp supports is fixed with a wire pressure plate 8 by screws; the wire clamp supports are located outside the input terminals and output terminals. The wire clamp supports can be fixed to the base shell by welding, or they can be integrally formed or fixed with screws, and their height matches the input terminals or output terminals.

[0023] Meanwhile, in practical applications, rubber pads are glued and fixed at the connection between the wire clamp support and the pressure plate. This protects the wires from damage and prevents them from loosening or falling off, improving the stability and reliability of use.

[0024] Furthermore, in this embodiment, heat dissipation slots 9 are provided on the side wall of the bottom shell, which helps to improve its heat dissipation effectiveness.

[0025] This utility model has positive effects: The structure of this utility model is reasonable. Its input terminals include a positive terminal, a negative terminal and a ground terminal. It can be connected with three or two wires as needed, thereby improving its versatility. In addition, the positive output terminal is located between the first negative output terminal and the second negative output terminal, which is also conducive to meeting dual-tone dimming control and improving the control effectiveness and stability reliability.

[0026] Furthermore, both ends of the bottom shell are equipped with wire clamp supports, and the top surface of the wire clamp supports is fixed with a wire pressure plate by screws, which can clamp and position the input and output wires, thereby improving tensile strength, ensuring the stability and reliability of the connection point, making it less prone to loosening or falling off, and making it highly applicable.

[0027] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
