Description
PLM-25 is a 25W economical AC/DC LED power supply series. Incorporating a
built-in active PFC design, PLM-25 provides a high Power Factor value greater
than 0.9. In addition, with the low no load power consumption below 0.5W, and
the setup time less than 500ms, PLM-25 is complied with the ErP regulation
required by European Union for lighting fixtures. PLM-25 is a class II
(without FG pin) power unit housed with the UL 94V-0 rated flame retardant
plastic case. The 1/0 terminals are designed with screw-less clamp style
terminal block that greatly simplifies the wiring installation. Two types of
models with different input voltage range are offered: PLM-25 series, which
operates from 110~295VAC, and PLM-25E series, which operates from 180~295VAC.
These two series are both constant current output design, supplying models
with the current of 350mA, 500mA, 700mA and 1050mA, respectively.

NOTE|
- All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- Please see “AC input voltage drop vs. output current characteristics” table.
- Derating may be needed under low input voltage, please check the static characteristic for more details.
- 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.
- 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
- Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
