  • Delivers 120W stable power for demanding projects
  • Adjustable 12V output with dual channels for flexible wiring
  • Auto-switching 110V/220V input suits global mains voltages
  • Built-in overload, over-voltage and thermal cut-offs protect gear
  • Fanless metal case runs silent and stays cool

120 W desktop power supply

This 120 W switching supply converts 110 V or 220 V AC to a regulated 12 V DC output rated at 10 A. It is built for indoor projects such as CCTV cameras, LED strips, 3D printers and audio amplifiers. Two output channels and a 10 % voltage-adjustment range give wiring flexibility. The unit is new and ships in a compact metal enclosure.

Fanless thermal design and protection

A perforated metal case provides passive cooling with no moving parts, so operation stays silent. Built-in safeguards include automatic overload cut-off, over-voltage cut-off, thermal cut-off and short-circuit protection. An internal EMI filter helps reduce conducted noise. The supply has passed a 100 % full-load burn-in test and supports parallel or redundancy operation.

Voltage selector and upgrade fit

A side-mounted selector switches the input between 110 V/115 V and 220 V/230 V; it is pre-set to the lower range for US mains. The supply replaces smaller 12 W to 60 W units when a project needs more current or dual output channels. It is not suited for outdoor or wireless-communication installations.

Questions about this item

How do I set the voltage selector switch on the side for 220 V mains?

Slide the side selector to the 220 V / 230 V position before connecting to AC 220 V; the unit ships set to 110 V / 115 V for US customers.

What ongoing maintenance does the fanless metal case require?

Keep the ventilation holes clear of dust; no internal fans or filters need replacement.

At what load does the automatic thermal cut-off engage first during sustained use?

The thermal cut-off activates if the case temperature rises excessively under continuous 120 W output.
