Summary:
working principle
High operating ambient temperatures require higher efficiency of the power supply to reduce its own heat. TinySwitch-III devices are ideal for this type of application because they provide a high efficiency, low cost solution.
The flyback power supply as shown can operate from an input voltage range of 165 - 265 VAC. It is capable of delivering 9 V, 1 A output current, making it ideal for applications such as electric furnace control at high ambient temperatures.
The AC input voltage is rectified by D1-D4 and filtered by C1 and C2. Fuse F1 is protected in the event of a serious fault. Inductors L1, L3 and capacitors C1, C2 and C9 provide differential mode filtering. Y capacitor C4 provides common mode filtering.

Barrier Terminal Block
Terminal blocks are used to facilitate the connection of wires. In fact, they are a piece of metal sheet sealed in insulating plastic. There are holes at both ends to insert wires and screws to fasten or loosen them. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without having to connect them It's very convenient and fast to weld or wind together. And it is suitable for a large number of wire interconnection. In the power industry, there are special terminal blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. A certain crimping area is to ensure reliable contact and enough current.
