HLK-2M05 AC-DC Power Supply Module 220V to 5V

Ultra-Compact PCB-Mount Power Module: Encapsulated mini power supply converts household AC grid voltage into a clean, regulated 5V DC output at up to 0.4A (2W max), designed for direct PCB through-hole mounting.

Wide Mains AC Input Range: Operates reliably on 100V–240V AC (50/60Hz) grid voltage, ensuring global compatibility with low standby power consumption and minimal heat dissipation.

Fully Isolated & Encapsulated Construction: Plastic shell potting provides electrical isolation ($3000\text{VAC}$ input-to-output), ingress protection, moisture resistance, and dustproofing for sensitive embedded electronics.

Silent Solid-State Operation: Fan-less, completely noiseless operation engineered for low output ripple and high energy efficiency in compact smart devices.

Integrated Safety Protections: Internal circuitry safeguards connected low-voltage microcontrollers against short circuits, continuous over-current, and input voltage surges.

Housing & Casing Style: Fully encapsulated, flame-retardant plastic potted housing engineered for compact PCB layout integration and thermal dissipation.

Contact & Terminal Style: Standard through-hole PCB pin contacts (AC, AC, -Vo, +Vo).

Technical Specifications:

Model: HLK-2M05.

Input Voltage: AC 100V–240V (50/60Hz).

Output Voltage: DC 5V.

Output Current: 0.4A Max (400mA).
