Overview
PLM-25E-500 is the model of this series: rated current 0.5A, rated power 25W, typical efficiency 86%.
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 I /O 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.

Test conditions and notes7
- 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.
- 7. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.

FAQ
What kind of LED application is the Mean Well PLM-25E-500 designed for?
The PLM-25E-500 is a constant current LED driver for fixtures that require a fixed 500 mA output. It is suited to LED assemblies operating within the model's stated current and output range, rather than constant-voltage loads. Its 25 W rating makes it a fit for lower-power commercial or architectural LED applications.
What are the main electrical specs of the PLM-25E-500?
This model is rated at 25 W with a constant output current of 500 mA. The product name identifies it as a 30-50 Vdc constant current LED driver. It is part of Mean Well's PLM enclosed LED driver range with built-in active PFC and short-circuit protection.
What input range does the PLM-25E-500 support?
The PLM-25E-500 is the E-type version in this series, which the product data lists for 180-295 VAC input. That makes it appropriate for 230 VAC markets rather than universal 110 VAC input applications. Buyers needing broader AC input coverage should check the non-E version in the same PLM-25 family.
Is the PLM-25E-500 suitable for enclosed or touch-accessible lighting products?
This model uses a fully isolated plastic case and is described as a Class II power unit, so it is built for isolated LED driver use. The plastic enclosure and free-air convection cooling make it suitable where a compact enclosed driver format is needed. Final suitability still depends on the fixture's thermal and compliance requirements.
What operating environment is this LED driver rated for?
The listed operating temperature range is -30 C to 45 C. Cooling is by free air convection, so it is intended for applications that can stay within that ambient range without forced cooling. It is a better fit for indoor or protected environments that match those thermal limits.
Does the PLM-25E-500 include dimming?
No. The product data lists dimming control as none, so this model is intended for non-dimming constant current LED applications. If dimming is required, a different driver series or variant would be a better choice.
What warranty comes with the Mean Well PLM-25E-500?
The specified warranty period for this model is 2 years. That aligns with the product description for the PLM series entry provided here. For procurement or project documentation, this gives a clear baseline warranty term for the driver.
