12V 3A / 5A DC Power Adapter

Product Overview

This 12V Regulated Switch-Mode DC Power Adapter provides quiet direct current power from standard universal AC mains. It works with input voltages from 100V to 240V AC making it suitable for use anywhere in the world. Available in two output options—3A (36W). 5A (60W)—this external power supply delivers high-efficiency power conversion while keeping performance consistent and reliable.

The adapter comes with an industry- 5.5mm x 2.1mm barrel plug, which also fits 2.5mm connectors. The center-positive design makes it easy to connect to a range of electronic devices that need more power. It is especially well-suited for equipment that draws a lot of current such as analog audio amplifiers, CCTV security cameras, SMD LED light strips and embedded development boards.

Key Features & Benefits

• Stable Switch-Mode Regulation (SMPS): This power adapter uses pulse-width modulation technology to ensure a clean steady 12V DC output. The result is low ripple and minimal switching noise helping your connected devices run smoothly without interference.
• Universal AC Input: The power adapter accepts input from 100V to 240V AC at 50/60 Hz. This means you can use it anywhere in the world without needing voltage converters or adapters.
• Comprehensive Circuit Protection: Built-in safety systems automatically respond when problems occur protecting both the device and the power supply. The protections include:
• OVP (Over-Voltage Protection): Prevents damage from voltage spikes.
• OCP (Over-Current Protection): Stops current flow that could harm connected equipment.
• SCP (Short-Circuit Protection): Safeguards against circuits inside the circuit.
• OTP (Over-Temperature Protection): Shuts down the unit if internal temperature gets too high preventing overheating.
• Standard Barrel Termination: The connector uses a 5.5mm x 2.1mm center- barrel plug. Its made with materials and includes a molded strain relief to resist repeated bending and physical stress over time.
• Cool Silent Operation: Thanks to its solid-state design this power adapter runs quietly and does not need a fan. There’s no noise during operation. It uses less energy when idle making it ideal for long-term use in sensitive environments, like home studios or office setups.
