Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Tolerance : includes set up tolerance.
  3. 3. Derating may be needed under low input voltage. Please check the static characteristic for more details. Please connect L line to the positive pole and N line to the negative pole under DC input.
  4. 4. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
  5. 5. This product is not intended for LED lighting luminaire applications EU and China.(In the EU and China the LPF/NPF/XLG/XLC/XLN series are recommended.)
  6. 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
  7. 7. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

What is the APC-12-350 typically used for?

The Mean Well APC-12-350 is typically used for small constant-current LED lighting and moving sign applications. It delivers 350mA constant current with 12.6W rated power over a 9-36V output range, making it a fit for LED loads designed around a 350mA drive current.

Is the APC-12-350 a good fit for 350mA LED loads?

Yes. The APC-12-350 is built as a constant-current LED driver rated at 350mA, so it should be matched to LED loads designed for that current level. The connected LED load also needs to stay within the driver's 9-36V output range and 12.6W rated power.

Can the APC-12-350 be used for indoor sign or accent lighting projects?

Yes. Indoor sign lighting, light-duty decorative lighting, and small LED assemblies are typical uses when the electrical requirements match the driver's 350mA constant-current design and 9-36V, 12.6W output.

Will the APC-12-350 run on standard AC mains input?

Yes. The specified input range is 90-264VAC, so the APC-12-350 can operate from common 120V and 240V AC mains systems within that range. That makes it practical for a wide range of general lighting installations.

Is the APC-12-350 suitable for exposed outdoor installation?

No. The APC-12-350 has an IP42 rating, which means it should generally be used indoors or in a protective enclosure rather than in direct outdoor exposure. Its listed working temperature is -30°C to +70°C (with derating), but enclosure protection still matters.

How does the APC-12-350 compare with other APC models?

The APC-12-350 provides 12.6W at 350mA with a 9-36V output range, while the APC-12-700 provides the same 12.6W at 700mA with a 9-18V range. The main choice is whether your LED load needs 350mA or 700mA constant current and which output voltage range it requires.
