Test conditions and notes12

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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Please refer to "DRIVING METHODS OF LED MODULE".
5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
6. A type only.
7. 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.
8. 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)
9. 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.
10. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
11. This product is not suitable for LED lighting applications in China.(It is recommended to use the LPF/NPF/XLG/XLC/XLN series in China)
12. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the HLN-40H-48A for 48V LED signage?

Yes, it can be used for 48V signage, either as a 48V constant-voltage supply or in constant-current mode for loads that operate within the 28.8-48V CC region. It supplies up to 0.84A with a maximum output of 40.3W, and signage is a typical application.

Is this driver suitable for 48V linear lighting fixtures?

It is suitable for 48V linear lighting fixtures that need up to 0.84A, whether they take a 48V constant-voltage supply or are driven directly within the 28.8-48V constant-current region. The fixture also needs to remain within the driver's 40.3W output limit.

Can the HLN-40H-48A power a 48V LED strip?

Yes, within its limits. The driver has a constant voltage + constant current characteristic, so it can run a 48V constant-voltage strip (output adjustable 44-53V) at up to 0.84A, or drive LEDs directly in constant-current mode within the 28.8-48V region. Keep the strip load within 40.3W.

Is the HLN-40H-48A okay for outdoor or washdown areas?

It is suitable for dust-exposed and splash-prone locations because the enclosure is rated IP64. That supports many sheltered outdoor uses, but IP64 covers splashing water rather than hose-down washdown or immersion, and the operating temperature range is -40°C to +50°C.

How do I calculate the maximum 48V LED strip length for this driver?

The driver's maximum output is 40.3W. To estimate length, divide 40.3W by the strip's rated power per meter, and check that the strip is a 48V product whose total current stays within 0.84A (or, for constant-current operation, within the 28.8-48V CC region).

What are the main output differences across the HLN-40H series?

The HLN-40H series spans 12V at 3.33A, 15V at 2.67A, 20V at 2A, 24V at 1.67A, 30V at 1.34A, 36V at 1.12A, 42V at 0.96A, 48V at 0.84A, and 54V at 0.75A. The HLN-40H-48A is the adjustable 48V version with 40.3W maximum output.
