Analog Technologies 300W 12V 25A Switching Power Supply

SKU CH-884K-VCE36

Enclosed 300W switching supply converts 90–264VAC to 12VDC at 25A with >85% efficiency

  • TypeSwitching Power Supply
  • Wide input range 90–264 VAC suits global mains
  • 12 V 25 A output delivers 300 W for demanding loads
  • Efficiency above 85 % cuts waste heat
  • All-metal 50 mm enclosure shields against EMI
  • Built-in fan maintains full-load performance up to 60 °C

Purpose & Audience

The Analog Technologies 300W switching power supply converts 110VAC or 220VAC mains to a stable 12VDC output at 25A. It suits builders of 3D printers, LED lighting installations, or custom computer projects needing a compact enclosed unit.

Decisive Specification

The supply delivers 12V at 25A for a total of 300W, accepting an input range of 90V to 264VAC. Efficiency exceeds 85 percent, and the unit withstands a 300VAC surge for five seconds. Operation is rated from 10°C to 60°C with a low-profile height of 1.97 inches.

Installation & Pitfalls

The all-metal enclosure includes a built-in long-life fan and mounts in a 50mm profile, but forced airflow must remain unobstructed for full-load reliability. Verify that the 25A limit covers peak inrush current of attached devices, and ensure wiring gauge matches the output current to avoid voltage drop.

Questions about this item

How much continuous 12 V current can this supply deliver inside a 3D printer or PC build?

It provides up to 25 A at 12 VDC, giving a full 300 W of regulated output for steady loads.

What AC input range does the unit accept and what does that mean for worldwide use?

The supply auto-ranges from 90 V to 264 VAC, so it runs on 110 V or 220 V mains without a selector switch.

Will the 1.97-inch tall metal case fit in a standard 1U rack slot or tight printer enclosure?

At exactly 50 mm (1.97 in) high, the all-metal enclosure matches a 1U profile and includes mounting flanges for secure installation.
