MEAN WELL SPV-300 300W Single Output with PFC Function

Product Usage Instructions

• Ensure the power supply is disconnected before installation. Connect the input terminals to the AC power source following the specified voltage range. Connect the output terminals to the intended load.
• The output voltage can be adjusted programmable from 20% to 110% using a 1~5.5VDC external control signal. Ensure proper calibration based on your application requirements.
• The power supply features a built-in remote ON-OFF control for convenient operation. Follow the user manual to understand the remote control functionality and wiring.
• The built-in fan speed control helps in maintaining optimal operating temperatures. Monitor the fan speed and adjust as needed to ensure efficient cooling.
• The power supply offers protection against short circuits, overload, over-voltage, and over-temperature. Familiarize yourself with these protections and take necessary precautions during usage.

FAQ

• Q: How do I know if the power supply is operating within the specified voltage range?
• A: You can use a multimeter to measure the output voltage and ensure it falls within the specified range of 88 ~ 264VAC.
• Q: Can I connect multiple loads to the power supply?
• A: It is recommended to connect only one load per power supply to prevent overloading and ensure stable operation.
• Q: What should I do in case of a short circuit?
• A: If a short circuit occurs, immediately disconnect the power supply from the mains and troubleshoot the issue before reconnecting.

SPECIFICATION

NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25°C 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. Tolerance: includes set up tolerance, line regulation, and load regulation.
4.  The power supply is considered a component that will be installed into the final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.’ (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
