12V 450mA 5.4W Isolation Switching Power Supply Module

Description

Product Overview

The 12V 450mA 5.4W Isolation Switching Power Supply Module is a compact, high-efficiency AC-DC converter designed to power industrial controls, embedded systems, IoT devices, and automation equipment directly from a wall outlet. Rated at 5.4 Watts (12V @ 450mA), this encapsulated module eliminates the need for bulky external power bricks by converting hazardous AC mains voltage (85V–265V) into a stable, regulated 12V DC output.

This module is an ideal power solution for relays, solenoid valves, LED lighting strips, wireless communication modules, PLCs, Arduino, ESP32, STM32, and various industrial sensors. Unlike traditional linear transformers that waste energy as heat, this switching mode power supply (SMPS) achieves up to 82% efficiency while maintaining a compact footprint.

The module features a built-in high-frequency transformer that provides 3kV galvanic isolation between the dangerous high-voltage AC input and the low-voltage DC output, ensuring the safety of both your sensitive electronics and the personnel handling the equipment. Its fully encapsulated design protects against dust, moisture, and vibration, making it ideal for integration into industrial panels, home appliances, and commercial electronic products.

Key Features

• Compact Encapsulated Design: Fully potted module protects against dust, moisture, and physical stress, ideal for industrial environments and PCB mounting
