SKU CH-RMYW-81XEG MPN S-120-12

Converts 110/220V AC to 12V DC at 10A with selectable input voltage and adjustable output for CCTV, LED strips and industrial use

  • AC 110 V or 220 V selectable by switch for worldwide use
  • DC 12 V 10 A output delivering 120 W for CCTV and LED strips
  • Built-in cooling fan activates automatically under load
  • Metal enclosure rated from -40 °C to 65 °C operating temperature
  • CCC, FCC and CE safety compliance for regulated installations

12 V 10 A 120 W Switching Supply

The Vszerda S-120-12 converts AC 110 V or 220 V mains into a regulated DC 12 V output rated at 10 A and 120 W. A built‑in selector switch sets the input range before power‑on. The metal enclosure measures 7.87 inch by 3.93 inch by 1.77 inch and weighs 479 g. Seven screw terminals handle AC input, DC output and a 15 % voltage adjustment. An automatic fan provides cooling.

Suits CCTV, LED strip and industrial automation

Installers running security cameras, LED lighting or broadcast equipment that demand stable 12 V DC will find the wide input range and CCC, FCC and CE compliance convenient. The unit operates from −40 °C to 65 °C with 20 % to 90 % non‑condensing humidity. Builders who need a different output voltage, a fanless design, a smaller enclosure or battery‑backup functionality should look at other power solutions.

Adjustable 12 V output with 15 % trim range

The +V/ADJ terminal lets you vary the DC output by roughly 15 % around the nominal 12 V, which is the single specification that determines whether this supply matches the load’s voltage tolerance. Input frequency covers 50 Hz and 60 Hz. Start‑up, rise and hold times are 200 ms, 100 ms and 30 ms respectively.

Questions about this item

Will the S-120-12 run from my existing 110 V mains wiring without rewiring?

Yes, the unit has a dual-input switch; set it to 110 V before powering on and it will accept your existing AC supply.

How can I verify the S-120-12 is delivering a stable 12 V after installation?

Measure the V+ and COM terminals with a multimeter; the output should read 12 V DC and the ADJ trimmer allows ±15 % adjustment if needed.

Does the S-120-12 include mounting screws or output cables, or must I source them separately?

The package contains only the power supply itself; mounting screws for the 2.5 mm holes and any DC output cables must be purchased separately.
