Test conditions and notes12

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTICS” sections for details.
6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
7. The driver 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)
8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
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. 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
12. 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.
14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-150-48A be used to drive 48V LED strips in a covered outdoor pergola or canopy?

Yes. The ELG-150-48A carries an IP65 rating, protecting it against dust and low-pressure water jets, which suits covered outdoor environments such as pergolas or canopies where rain splash may occur. Its 150.2W at 48V supports substantial strip loads in these applications.

What does the adjustable feature on the ELG-150-48A allow me to do?

The A suffix indicates the ELG-150-48A has a built-in trimmer potentiometer that allows field adjustment of the output voltage (43.2–52.8V) and current (1.56–3.13A), without requiring any external control signal. This is useful for fine-tuning LED brightness or matching the driver to specific LED module forward-voltage requirements on-site.

How much 48V LED strip can the ELG-150-48A power?

The ELG-150-48A outputs 150.2W at 48V with a 3.13A maximum. For a strip rated at 12W/m, that is approximately 12.5 m (150 ÷ 12 ≈ 12.5); for a 20W/m high-output strip, about 7.5 m (150 ÷ 20 = 7.5). Always confirm your strip's actual rated power per meter and apply appropriate derating for continuous operation.

Is the ELG-150-48A suitable for powering 48V LED panels in damp indoor environments like commercial kitchens?

Yes. The IP65 rating on the ELG-150-48A provides full dust protection and resistance to water jets from any direction, making it appropriate for damp indoor environments including commercial kitchens or food-service areas where splashing or cleaning occurs.

Can the ELG-150-48A operate in cold storage or refrigeration lighting applications?

Yes. The ELG-150-48A is rated for a case temperature (Tcase) of -40°C to +90°C, covering the temperature ranges found in cold storage and refrigeration environments. The IP65 case protects against dust and water spray, but the sheet specifies 20–95% RH non-condensing working humidity, so mount it where condensation does not form on the driver.

How does the ELG-150-48A compare to the ELG-150-48 for an indoor commercial installation?

Both models share the same 150.2W, 48V, 3.13A output and physical dimensions. The ELG-150-48A adds a built-in trimmer for output adjustment, making it more flexible for commissioning. The trade-off is that the A variant is rated IP65 rather than the IP67 of the base ELG-150-48, so for fully outdoor or submersion-risk environments, the ELG-150-48 offers higher ingress protection.

Can the ELG-150-48A be used as a constant-current driver for 48V LED modules in retail display cases?

Yes. The ELG-150-48A operates in constant-current mode within its 24–48V CC region, which is compatible with 48V LED modules used in retail display cases and showcase lighting. The field-adjustable output also allows fine-tuning of light output during fixture commissioning without changing components.
