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-12-500 for a 500mA LED downlight?

Yes, if the downlight is designed for 500mA constant current and the LED load falls within the 15-24V CC range. This model is a 12W constant current driver, so it should not be used as a constant voltage source.

Is the PLM-12-500 suitable for constant current LED signage modules?

It is suitable for signage modules that are specified for 500mA constant current and whose forward voltage stays within 15-24V. That makes it a better fit for constant current modules than for 12V or 24V constant voltage signage products.

Would the PLM-12-500 work for a compact LED array in the 12W class?

Yes, if the array is designed for 500mA constant current and its total forward voltage is within 15-24V. Its 12W power level fits compact LED arrays better than higher-power assemblies.

How do I match the PLM-12-500 to the right LED load?

Match it to LEDs that need 500mA constant current and whose combined forward voltage fits the 15-24V CC output range. The number of LEDs depends on each LED's forward voltage, so there is no single correct LED count.

Is this driver meant for exposed outdoor conditions?

The operating temperature range is -30°C to +50°C, and the unit is a Class II design rated IP30. IP30 gives no protection against water, so it is not meant for exposed outdoor conditions; wet or dusty environments must be handled by the enclosure or fixture design.
