AC/DC to DC Step Down Buck Converter AC 0-28V to DC1.25V-30V Voltage Regulator Board Volt Power Supply Module LM317/LM337

Features:1.Using high-quality materials and ensuring product quality2.The rectifier section adopts four independent rectifier diodes, each with an anti-interference capacitor in parallel, which can prevent useful signals (usually high-frequency signals) and power frequency signals (50 Hz) from being mutually modulated on the rectifier diode, resulting in interference signals that interfere with the normal operation of the machine, eliminate "modulated AC sound", and eliminate interference sources for subsequent circuits from the root.3.The entire circuit board is grounded at one point, even if multiple instruments and circuits share the same power board, there will be no power ground loop. Without a ground loop, there will be no AC sound. Solving the problem of ground wire loop from the source4.Compact appearance and beautiful arrangement of components5.Widely used, the product comes with output short circuit protection, overcurrent, and overheating protectionParameters:Input: AC0-28V (not exceeding 28V!)Adjustable output voltage as low as 1.2V. Ensure a 1.5A output current.The typical linear adjustment rate is 0.01%. The typical load adjustment rate is 0.1%. 80dB ripple suppression ratio.Voltage output range: DC1.25V-30V, continuously adjustable positive and negative voltagePackage include:Adjustable regulated power board * 1
