myVolts 12V 30A 360W Switching Power Supply for 3D Printer LED Lights

SKU CH-XVKQ-HRNHX

Converts 110V or 220V AC to 12V DC at 30A with short-circuit, overload and over-voltage protection plus independent PTC-fused outputs and LED status indicators

  • TypeAT
  • Converts AC 110V/220V to stable 12V DC 30A 360W output
  • Multiple protections include short circuit, overload 105%-150% and over-voltage 115%-135%
  • Independent PTC fuse per output with LED indicator keeps remaining channels running if one fails
  • Auto on/off cooling fan maintains low temperature operation in 0-40°C range
  • CCC, FCC and CE safety compliance with metal aluminium case for durability

360 W switching supply for 12 V projects

This 12 V 30 A switching power supply converts AC 110 V or 220 V mains to a regulated 360 W DC output. It targets builders running WS2812B or WS2801 LED strips, 3D printers, CCTV rigs or similar 12 V loads. The metal-cased unit measures 8.42 in by 4.44 in by 1.9 in and weighs 345 g. It carries CCC, FCC and CE compliance marks.

Dual-voltage input with independent fused outputs

A slide switch selects the 100–120 V or 200–240 V input range before power-up. Each output channel has its own PTC fuse and LED indicator, so a fault on one rail leaves the others running. The supply fits indoor benches or enclosures that can keep combustible material 50 cm from the air outlet and leave 5 cm clearance around the case for airflow. Professional installation is advised.

Auto-reset protection

Overload protection trips at 105–150 % load, over-voltage at 115–135 % (13.8–16.2 V), and short-circuit protection cuts the output instantly; all modes auto-reset once the fault clears. An auto on/off fan keeps the case cool during continuous operation up to 40 °C ambient, with storage tolerance down to -20 °C. The non-detachable shell stays hot under load, so direct contact must be avoided while running.

Questions about this item

How long can I run this 360W supply at 30A before the 40°C operating limit forces it to throttle?

The unit is rated for continuous operation up to 40°C ambient; an auto on/off cooling fan engages to keep internal temperatures in check during sustained 30A loads.

What noise and heat should I expect from the cooling fan when this supply runs all day at full load?

An automatic fan spins only when needed, so noise stays low at light loads and rises under heavy 360W output; the metal case and aluminium base spread heat across the 8.42×4.44×1.9 in enclosure.

Which AC mains cable and voltage selector setting do I need before this 12V 30A supply will power my 3D printer?

You must provide a standard IEC C13 mains lead and set the input selector to 110V or 220V to match your local supply before connecting the DC output terminals.
