Ultra-thin AC-DC power module, compact green PCB with solder pins

Manw

Manw HLK-20M12 12V 20W AC-DC Power Supply

SKU CH-PR5D-HZP0J

Compact 12 V 20 W AC-DC module accepts 90–265 V input with 3000 Vac isolation and built-in short-circuit protection

  • Ultra-thin module fits tight enclosures
  • Universal 90 ~ 265Vac input suits global mains
  • Low ripple and noise delivers clean 12V output
  • circuit and over-current protection with self-recovery
  • 3000Vac isolation withstands high-voltage transients

Compact AC-DC Module for Embedded Projects

The Manw HLK-20M12 converts mains voltage into a regulated 12 V rail rated at 20 W. Its ultra-thin profile suits tight enclosures in home-automation nodes, sensor hubs or custom IoT gateways where board space is at a premium.

Steady Output Under Continuous Load

Universal input accepts 90 V to 265 Vac so the module rides through brown-outs and regional voltage differences without shutting down. Low ripple and noise keep sensitive analog front-ends stable, while built-in short-circuit and over-current protection auto-recovers to maintain uptime in unattended installations.

3000 Vac Isolation Barrier Decides Fit

Input-to-output withstand voltage of 3000 Vac provides the safety margin required for mains-connected designs. If your schematic demands a lower isolation rating or a different output voltage, this module will not meet the specification.

Questions about this item

How much heat does the HLK-20M12 produce when running continuously at 20 W?

The module uses a compact, ultra-thin design with no fan, so heat is dissipated through the case. At full 20 W load the surface becomes warm but stays within the limits set by its 3000 Vac isolation rating.

What mains wiring and DC-side connections are needed to install this supply?

Connect the AC input pins to a 90–265 Vac source (220 V nominal) and the DC output pins to your 12 V load; no extra converters or cables are included in the package.

Will the 12 V output run legacy 12 V gear that draws up to 20 W without voltage sag?

The unit delivers a regulated 12 V with low ripple and built-in over-current protection that self-recovers, so older 12 V devices drawing up to the rated 20 W will operate steadily.
