Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. Length of set up time is measured at cold first start. Turning ON/OFF the driver may lead to increase of the set up time.
4. Aux. 12V will be damaged with short circuit; It will not be available with dimming off or output no load condition.
5. 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.
6. 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).
7. 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
8. 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.

FAQ

Can I use the ODLV-45A-48 for 48V LED strip lighting?

Yes, this model provides 48V constant voltage output with 45.12W maximum power and 0.94A output current. It is intended for 48V LED strip systems whose total load stays within 45.12W.

Is the ODLV-45A-48 a good choice for 48V signage lighting?

It can be used for 48V constant voltage sign lighting, channel letter lighting, or light box systems that draw no more than 45.12W. The IP67 waterproof rating is useful where signage power supplies face outdoor exposure.

Can this driver power 48V linear or accent lighting in commercial spaces?

It is suitable for 48V constant voltage linear lighting or accent lighting where the fixture load is within 45.12W. With its IP67 rating and a working case temperature (Tcase) of -20°C to +85°C, with load derating at higher temperatures, it suits a wide range of indoor and outdoor installations.

How do I estimate the maximum 48V LED strip length for the ODLV-45A-48?

Use the driver's maximum output power of 45.12W and divide it by your strip's rated power per meter. The sizing formula is 45.12W ÷ strip W/m, and you should check your strip rated power per meter before deciding the final length.

Is the ODLV-45A-48 safe for outdoor or wet-location use?

Yes, the housing is rated IP67, so it is designed for waterproof use in wet or exposed locations. Its working temperature is specified as a case temperature (Tcase) of -20°C to +85°C, with load derating at higher temperatures, which supports outdoor lighting environments.

What are the main differences between the ODLV-45A-48 and the other ODLV siblings?

In the 45W range, the listed siblings are ODLV-45-12 at 36W 12V 3A, ODLV-45-24 at 45.12W 24V 1.88A, ODLV-45-36 at 45W 36V 1.25A, ODLV-45-48 at 45.12W 48V 0.94A, ODLV-45-60 at 45W 60V 0.75A, ODLV-45A-12 at 36W 12V 3A, ODLV-45A-24 at 45.12W 24V 1.88A, ODLV-45A-36 at 45W 36V 1.25A, ODLV-45A-48 at 45.12W 48V 0.94A, and ODLV-45A-60 at 45W 60V 0.75A. The ODLV-45A versions add a 12V auxiliary DC output rated at 50mA that the standard ODLV-45 versions do not have. This model's defining specs are 45.12W, 48V, and 0.94A in the ODLV-45A group.
