5V 600mA 3.5W switching power supply module

Description

Product Overview

The 5V 600mA Switching Power Supply Module is a compact, high-efficiency AC-DC converter designed to power your microcontroller projects, IoT devices, and embedded systems directly from a wall outlet. Rated at 3.5 Watts (5V @ 600mA), this tiny module eliminates the need for bulky power bricks by converting hazardous AC mains voltage (85V–265V) into a stable, regulated 5V DC output.

This encapsulated switching power supply is a perfect solution for powering Arduino, ESP32, STM32, relay modules, LED strips, and sensor networks. Unlike traditional linear transformers that are heavy and inefficient, this switching mode power supply (SMPS) achieves up to 74% efficiency while staying cool, thanks to its modern flyback topology .

Because the module uses a high-frequency transformer and complies with international safety standards, it provides complete electrical isolation between the dangerous high-voltage AC input and the low-voltage DC output. This ensures the safety of both your sensitive electronics and the person handling the equipment .

Its fully encapsulated plastic case protects against dust, moisture, and accidental contact, making it ideal for integration into home appliances, automation panels, and commercial electronics .

Key Features

• PCB Mount Design: Fully encapsulated plastic case can be soldered directly onto a printed circuit board (PCB), making it ideal for high-volume production and permanent installations .

• Universal AC Input: Accepts a wide input voltage of 85V to 264V AC (or 90-264V depending on the exact variant), making it compatible with mains power worldwide (110V, 220V, 240V) without any jumpers.

• Efficient Switching Topology: Features high efficiency (up to 74%) and low heat generation, minimizing energy waste and ensuring long-term reliability in enclosed spaces .

• Sufficient 600mA Capacity: Provides a steady 5V output with 600mA continuous current, capable of powering most low-power microcontrollers, wireless modules (ESP8266), and sensors simultaneously.

• Protected and Safe: Built-in overcurrent, short-circuit, and overload protections prevent damage to the module and your downstream devices during fault conditions .

• Low Output Ripple: Despite being a switching supply, it maintains low output ripple and noise, ensuring stable operation for sensitive analog circuits .

• Wide Operating Temperature: Rated for an ambient temperature range of -25°C to +60°C, suitable for a variety of indoor and light-industrial environments .

• Easy DIY Wiring: The module features standard through-hole pins (2.54mm pitch) for easy soldering to a PCB or for connecting wires manually using female jumper cables .
