Certifications & ratings

Input Voltage: 110~295VAC

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-25-350 for a 350mA LED downlight?

Yes, if the fixture is built for constant current operation at 350mA and the LED load falls within the 42-72V constant-current range. This model is a constant current driver, not a constant voltage power supply.

Is the PLM-25-350 a good fit for long-series small LED arrays?

It is intended for constant current LED arrays that need 350mA and a higher forward-voltage span. The usable CC output range is 42-72V, with a 25.2W rating.

Can this driver power constant current signage modules with a higher total forward voltage?

Yes, if the signage module string is designed for 350mA constant current and its total forward voltage stays within 42-72V. It should not be used in place of a constant voltage supply for fixed-voltage signage products.

What makes the PLM-25-350 compatible or incompatible with my LED load?

The LED load must require 350mA constant current, and its combined forward voltage must remain inside the 42-72V CC range. The number of LEDs depends on each LED's forward voltage, so compatibility is determined by current and total voltage rather than a specific LED quantity.

Can the PLM-25-350 handle cold or warm operating conditions?

Its specified operating temperature range is -30°C to +45°C. That gives it a defined working range for temperature-sensitive LED driver applications; the unit is IP30 approved, so it is not intended for wet or dust-heavy environments.
