Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Please see "AC input voltage drop vs. output current characteristics" table.
4. Derating may be needed under low input voltage, please check the static characteristic for more details.
5. Constant current operation region is within 60% ~100% rated output voltage. This is the suitable operation region for LED related applications, but please reconfirm special electrical requirements for some specific system design.
6. 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)
7. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
8. The models certified by CCC (GB/T19510.1, GB/T19510.213, GB/T 17743 and GB17625.1) are optional models. Please contact your MEAN WELL sales for more information.

FAQ

Can I use the PLM-12-350 with a 350mA LED downlight?

Yes, if the downlight is designed for 350mA constant current input and its LED load fits the 22-36V CC range. This 12.6W model is for constant current LED loads, not for constant voltage fixtures.

Is the PLM-12-350 a good fit for LED signage modules with longer series strings?

It can be, provided the signage module assembly is built for 350mA constant current and the total forward voltage stays within 22-36V. That higher CC range makes it more suitable for longer series LED strings than the lower-voltage 12W PLM variants.

Can this driver power a small LED array that needs lower current and higher string voltage?

Yes, that is the kind of load this model is aimed at when the array is rated for 350mA constant current and falls within 22-36V. Its 12.6W output is better aligned with modest-power arrays than with larger LED assemblies.

What should I check before pairing the PLM-12-350 with an LED module?

Confirm that the LED module requires 350mA constant current and that the combined LED forward voltage is within the 22-36V CC range. The actual number of LEDs depends on each LED's forward voltage, so compatibility is based on current and total voltage, not a fixed count.

Can the PLM-12-350 be used across a wide ambient temperature range?

It is rated for -30°C to +50°C operation, which supports use in a broad range of indoor or protected applications. It is a Class II design rated IP30, so the surrounding enclosure and exposure conditions still matter.
