myVolts S-350-5v 12V 29A 348W AT Power Supply

SKU CH-G118-KHSZH

12 V, 29 A AT switching supply delivering 348 W with over-temperature, short-circuit, overload and over-voltage protection plus a fan-cooled copper transformer

  • TypeAT
  • Universal 100–260 V AC input suits global mains voltages
  • 12 V / 29 A regulated output delivers 348 W for demanding loads
  • Over-temperature, short-circuit, overload and over-voltage protections safeguard connected gear
  • All-copper honeycomb transformer runs cool and maintains stable voltage
  • Built-in fan with 4500–5000 rpm speed and LED indicator ensures quiet, reliable cooling

AT Power Supply for CCTV and Projects

This 12 V AT switching unit delivers 29 A and 348 W for CCTV installations, radio equipment and custom computer projects. It accepts 100–120 V or 200–260 V AC input and includes short-circuit, overload, overvoltage, over-temperature and inrush-current protection. The silver alloy enclosure measures 215 × 115 × 50 mm and meets CE and RoHS requirements.

Installation and Common Issues

Mount the supply using its existing screw holes and connect the output leads to the 12 V load; the built-in fan runs continuously at 4 500–5 000 rpm to maintain airflow above 60 units. Ensure the input selector matches the local mains voltage before powering on. Builders who need adjustable voltage or ATX connectors will find this fixed-output AT unit unsuitable.

AT Interface Limits

The AT form factor provides a single 12 V rail without the standby or signal lines required by modern motherboards. Maximum continuous output is capped at 348 W, so loads exceeding 29 A will trigger overload protection. Systems that require multiple voltage rails, remote on/off control or higher power density must use a different supply topology.

Questions about this item

How do I confirm the 12 V 29 A output is stable after installation?

Check the LED power indicator on the unit; it lights when the 12 V rail is active and the fan spins at 4500-5000 rpm for cooling.

What comes in the box and what must I source separately?

The package includes one power supply unit only; you will need to provide an AC mains cable and any DC wiring or connectors for your load.

Which capacity should I choose for a 348 W 12 V project?

This single S-350-5v model delivers 348 W at 12 V 29 A, matching the stated requirement exactly.
