Ac-Dc 12V 300/450/1000Ma Converter Ac 220V To 5V Dc Step Down Transformer Power Supply Module With Multi Currents

Description: 1. Overcurrent Protection: Built-in high-precision current sensing electronic components + optimized circuit design, automatically cuts off power when current exceeds rated threshold, protects connected downstream devices from current surge damage and lowers equipment maintenance costs. 2. Over-temperature Protection: Integrated high-sensitivity temperature detection components, triggers protection mechanism once operating temperature exceeds safe range, prevents module burnout caused by overheating, effectively extends the service life of the module and connected equipment. 3. Overload Protection: Professionally tuned circuit process, activates protective intervention immediately when load exceeds rated capacity, avoids module damage under overload operation, ensures long-term stable power output for your devices. 4. Short Circuit Protection: Fast-response short-circuit protection circuit, stops power output instantly when output short circuit is detected, effectively avoids fire risk and device damage caused by short circuit, greatly improves power supply safety for all application scenarios. 5. High-efficiency Isolated Conversion: High-permeability magnetic core transformer with insulated shell, fully isolates input and output circuits, prevents electric leakage and signal interference, delivers stable regulated 12V DC output, compatible with most low-voltage electronic devices. 6. Mini Size Design: Miniaturized PCB integration process, occupies extremely small installation space, fits perfectly into compact equipment casings, meets the design requirements of miniaturized electronic projects and compact devices.
