HLK-PM12 AC-DC Power Supply Module 220V to 12V

Compact 3W 12V Output: Encapsulated mini power supply module converts household AC grid voltage into a clean, regulated 12V DC output at up to 0.25A (3W max), designed for direct PCB through-hole mounting.

Universal AC Input Compatibility: Operates seamlessly across a wide input voltage range of 100V–240V AC (50/60Hz) grid power with high conversion efficiency and low idle standby loss ($<0.1\text{W}$).

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

Silent Solid-State Operation: Fan-less, completely noiseless operation with low output ripple voltage, ideal for driving 12V relays, sensors, and low-power control electronics.

Integrated Circuit Safeguards: Internal automatic protection shields connected low-voltage components against short circuits, continuous current overloads, and mains power surges.

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

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

Technical Specifications:

Model: HLK-PM12.

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

Output Voltage: DC 12V.

Output Current: 0A – 0.25A Max (250mA).

Rated Power: 3W.

Cooling: Passive thermal dissipation via internal potting compound.
