ماژول پاور سوئیچینگ دارای خروجی 24 ولت 4 آمپر
هر سیستم یا مدار الکترونیکی نیاز به یک منبع تغذیه دارد که دارای خصوصیاتی مانند راندمان بالا، توان اتلافی پایین، سطح ولتاژ یا جریان کنترل شده و دقیق و ابعاد فیزیکی پایین و …باشد. خصوصیاتی که ترانس های سیم پیچ دار سنتی فاقد آن هستند. راه حل استفاده از
نابع تغذیه سوییچینگ (Switch Mode Power Supply: SMPS ) است. در این نوع منابع تغذیه تغییر توان الکتریکی از طریق تغییر سطح ولتاژ و یا تبدیل AC به DC ،DC به DC ,DC به AC و یا AC به AC میسر می شود.
پاور سوییچینگ ها توانایی تحمل بار زیاد را دارند و نویز بسیار کمی را ایجاد می کنند.
این ماژول پاور سوییچینگ که به صورت مبدل ولتاژ متناوب به ولتاز ثابت DC می باشد، دارای ولتاژ ورودی 85 تا 265 ولت متناوب و خروجی 24 ولتDC ، و جریان خروجی 4 آمپر می باشد. این ماژول دارای عملکرد پایدار و قابل اطمینان است که برای کنترل سیستم های صنعتی مناسب می باشد وابعاد آن 10.6× 5.7 × 2.8 سانتی متر است.
Description:
A switched-mode power supply SMPS or switcher is an electronic power supply that incorporates a switching
regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation
transitions, which minimizes wasted energy. A hypothetical ideal switched-mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time (also known as duty cycles). In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. This higher power conversion efficiency is an important advantage of a switched-mode power supply. Switched-mode power supplies may also be substantially smaller and lighter than a linear supply due to the
smaller transformer size and weight.
A basic isolated AC to DC switched-mode power supply consists of: Input rectifier and filter, Inverter
consisting of switching devices such as MOSFETs, Transformer, Output rectifier, filter, and Feedback and control circuit.
There are different circuit configurations known as topologies, each having unique characteristics, advantages, and modes of operation, which determines how the input power is transferred to the output. Most of the commonly used topologies such as flyback, push-pull, half-bridge and full-bridge, consist of a transformer to provide isolation, voltage scaling, and multiple output voltages. The non-isolated configurations do not have a transformer and the power conversion is provided by the inductive energy transfer. This power supply module exclusively adopts double-sided PCB design, the performance is more stable and more reliable! More suitable for power supply of industrial control system.
