HLK-PM01 AC-DC Power Supply Module 220V to 5V

Compact 3W 5V Output: Encapsulated mini power supply module converts AC grid power into a regulated, low-noise 5V DC output at up to 0.6A (3W max), engineered for direct PCB through-hole mounting.

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

Fully Isolated & Encapsulated Body: Flame-retardant plastic shell potting provides high input-to-output electrical isolation (3000VAC), dust resistance, moisture protection, and vibration dousing for delicate microelectronics.

Silent Solid-State Operation: Completely fan-less, noiseless operation with low output ripple voltage, designed specifically for powering sensitive microcontrollers and logic boards.

Integrated Circuit Protection: Internal automatic safeguards shield connected low-voltage devices against short circuits, continuous current overloads, and mains power surges.

Housing & Casing Style: Flame-retardant plastic potted housing designed 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-PM01.

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

Output Voltage: DC 5V.

Output Current: 0A–0.6A Max (600mA).

Rated Power: 3W.

Cooling: Passive thermal dissipation via internal potting compound.
