{"title":"Switching Power Supply","description":"\u003cp\u003eA switching power supply is an efficient electronic device designed to convert high-voltage alternating current (AC), typically 110V or 220V, into various levels of low-voltage direct current (DC) such as 5V, 12V, 24V, or 36V, depending on the application. It works by first rectifying and filtering the AC input into DC, then using high-speed switching transistors to rapidly turn the current on and off. This switched signal is passed through a transformer or inductor, which adjusts the voltage level and provides isolation. The resulting voltage is then rectified and filtered again to produce a stable DC output. Switching power supplies are highly efficient, compact, and widely used in electronic devices, industrial equipment, and systems where multiple DC voltages are required from a single AC source.\u003c\/p\u003e","products":[{"product_id":"switching-mode-power-supply-smps-s-120-24-24v-5a-120w","title":"Switching Mode Power Supply Smps S-120-24 - 24v 5a 120w","description":"\u003cp\u003eA 24v switching-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.
