This power entry module, series DC21, is designed to save space and minimize time and cost during the assembly of electronic devices. The AC inlet and on/off switch functions are internally wired and connect to a printed circuit board with 3-pins. The low profile design eliminates the handling of wires that may risk damage or electro-static exposure to sensitive, integrated circuits. A rear cover further insulates the module from other components. Connecting to a PC board also minimizes emissions that invariably result from the use of wire connections.
