Test conditions and notes11
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Please refer to "DRIVING METHODS OF LED MODULE".
  5. 5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
  6. 6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
  7. 7. The power supply is considered a component which will be installed into a 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)
  8. 8. Heat Sink HS1,HS2 can not be shorted.
  9. 9. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  10. 10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
  11. 12. This product is not suitable for LED lighting applications in China.

FAQ

What is the output rating of the Mean Well HLP-80H-48?

The HLP-80H-48 is an 80W class open frame AC-DC power supply with a 48V DC output. Its rated output current is 1.7A, making it suitable for applications that require regulated 48V power within that power range.

What kinds of applications is the HLP-80H-48 designed for?

This model is intended for built-in LED lighting systems and other equipment that needs a compact 48V open frame power supply. Its 3-in-1 dimming, adjustable output current, and open frame form factor make it relevant for enclosed OEM and commercial lighting designs.

What input voltage range does the HLP-80H-48 support?

The HLP-80H-48 accepts a universal AC input range of 90-305VAC and also supports 127-431VDC input. That wide range helps it fit projects that need flexibility across different mains power environments.

Can the HLP-80H-48 be used in demanding temperature conditions?

Yes. This power supply is rated for operation from -40°C to +70°C, with derating at higher temperatures as noted in the product data. Working humidity is specified as 20-95% RH non-condensing.

What protection features are included in the HLP-80H-48?

The HLP-80H-48 includes short circuit, over current, over voltage, and over temperature protection. Depending on the fault type, it uses automatic recovery or requires re-powering after the fault condition is removed.

What makes the HLP-80H-48 different from a basic fixed-output power supply?

Compared with simpler fixed-output units, this model includes active power factor correction, 3-in-1 dimming, and an adjustable output current range of 1.36-1.7A. The datasheet also identifies it as an LED power supply meant to operate in its constant current region, which can matter for commercial product selection.
