HLK-5M12 AC-DC Power Supply Module 220V to 12V

Compact 5W 12V Output: Encapsulated mini power supply module steps down AC grid voltage into a clean, regulated 12V DC output at up to 0.42A (5W max), designed for direct PCB through-hole mounting.

Universal AC Input Compatibility: Accepts a wide input voltage range of 100V–240V AC (50/60Hz) mains power with high conversion efficiency and low standby energy draw.

Fully Isolated & Encapsulated Body: Flame-retardant plastic shell potting provides $3000\text{VAC}$ input-to-output electrical isolation, ingress protection, moisture resistance, and vibration dampening for sensitive circuits.

Silent Solid-State Operation: Fan-less, completely noiseless operation engineered for low output ripple voltage, ideal for powering relays, sensors, and 12V control logic.

Integrated Safety Features: Built-in safeguards protect connected components against short circuits, continuous current overloads, and mains input voltage surges.

Housing & Casing Style: Fully encapsulated plastic potted housing engineered for compact PCB layout integration and optimal heat management.

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

Technical Specifications:

Model: HLK-5M12.

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

Output Voltage: DC 12V.

Output Current: 0A–0.42A Max (416mA).

Rated Power: 5W.

Cooling: Passive thermal dissipation via internal potting compound.

Color: Black shell with white pin identification legend.

Usage Advice: Calculate continuous load draw to remain within the 5W (416mA) rated threshold. Ensure proper PCB creepage and clearance distances between AC mains high-voltage traces and low-voltage DC traces.

Maintenance: Solid-state potted module requires zero routine physical maintenance. Ensure reasonable passive airflow inside small project enclosures.

Essential Embedded 12V Power Node: Position as the ideal PCB-mount step-down converter for 12V relay control boards, home automation nodes, smart valve controllers, access control hardware, and 12V sensors.

Highlight Compact PCB Integration & 12V Conversion: Emphasize its ability to convert mains AC directly into 12V on custom circuit boards without requiring external bulky wall adapters or open-frame supplies.
