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

Compact 5W Power Delivery: Encapsulated mini power supply module converts household AC grid voltage into a clean, regulated 5V DC output at up to 1A (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) grid power with high energy conversion efficiency and low standby loss.

Fully Encapsulated & Isolated Housing: Plastic shell potting provides 3000VAC input-to-output electrical isolation, moisture resistance, dustproofing, and vibration protection for sensitive logic components.

Silent Convection Operation: Fan-less, completely noiseless solid-state operation with low output ripple voltage, ideal for microcontrollers and sensitive digital circuits.

Integrated Circuit Safeguards: Features built-in automatic protection against output short circuits, continuous current overloads, and input voltage surges.

Housing & Casing Style: Flame-retardant plastic potted housing engineered for compact PCB layout integration and natural thermal dissipation.

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

Technical Specifications:

Model: HLK-5M05.

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

Output Voltage: DC 5V.

Output Current: 0A – 1A Max (1000mA).

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 operate within the 5W (1A) rated threshold. Ensure adequate PCB creepage and clearance distances between AC high-voltage and DC low-voltage traces.

Maintenance: Fully potted solid-state module requiring zero physical maintenance. Ensure reasonable ventilation inside tiny project enclosures.

Essential Embedded 5V Power Node: Position as the ideal step-up power choice over the 2W variant for power-hungry IoT nodes (ESP32 with display, Raspberry Pi Pico projects, multi-relay boards, and smart home actuators).

Highlight Direct PCB Mounting & 1A Capability: Emphasize its 5W (1A) output capacity housed in a tiny PCB-mountable form factor that replaces bulky external AC adapters.
