Product Usage Instructions

Installation:

Ensure proper ventilation around the power supply unit.
Connect the input power according to the specified voltage range.

Connect the output leads to the LED lights or devices as per the rated current and voltage requirements.

Operation:

Switch on the input power and verify the LED lights are functioning correctly.
Monitor the temperature of the power supply during operation to ensure it stays within the specified working temperature range.

Maintenance:

Regularly check for any loose connections or signs of damage.

Clean the power supply unit periodically to prevent dust buildup that can affect performance.

FAQ:

Q: What should I do if the power supply unit overheats during operation?
A: If the power supply unit overheats, immediately switch it off and allow it to cool down before resuming operation. Check for any obstructions to ventilation and ensure proper airflow around the unit.
Q: Can I connect multiple LED lights to one power supply unit?
A: The maximum number of LED lights that can be connected to one power supply unit depends on the total power consumption of the lights and the maximum load capacity of the power supply unit. Refer to the product specifications for guidance on this.

Description

PLM-12 is a 12W economical AC/DC LED power supply series. Incorporating a built-in active PFC design, PLM-12 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 of less than 500ms, PLM-12 has complied with the ErP regulation required by the European Union for lighting fixtures.

PLM-12 is a class II (without FG pin) power unit housed with the UL 94V-0 rated flame retardant plastic case. The 1/O terminals are designed with a screw-less clamp-style terminal block that greatly simplifies the wiring installation. Two types of models with different input voltage ranges are offered: the PLM-12 series, which operates from 110~295 VAC, and the PLM-12E series, which operates from 180~295VAC. These two series are both constant current output designs, supplying models with currents of 350mA, 500mA, 700mA, and 1050mA, respectively.

NOTE	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 the “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 the EMC Directive on the complete installation. (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. ※ Product Liability Disclaimer: For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx.
