Test conditions and notes5
- 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 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. The power supply is considered a component which will be installed into a final equipment. 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. 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).

FAQ
What is the ADS-15548 typically used for?
The Mean Well ADS-15548 is typically used in higher-voltage DC systems that need a 48V main output and an auxiliary 5V output. With 154.2W of rated power and 2.9A on the main 48V output, it is a good fit for applications that need a higher-voltage rail while still benefiting from a dual-output power supply design.
Can the ADS-15548 support 48V DC system loads?
Yes. The ADS-15548 provides a main 48V output rated at 2.9A, making it suitable for systems designed around that voltage class when the demand stays within that 2.9A rating and the unit's 154.2W total rated power. It is the 48V option in this ADS group rather than a lower-voltage 12V or 24V unit.
Is the ADS-15548 a good fit for systems that need a 48V rail plus a 5V auxiliary output?
Yes. The ADS-15548 is useful in designs where the main equipment needs 48V DC and supporting electronics benefit from a separate 5V output. That dual-output structure can make it more practical for mixed-voltage system layouts than a supply that only provides a single 48V rail.
Can the ADS-15548 be used where a higher-voltage output is needed instead of 12V or 24V?
Yes. The ADS-15548 is intended for applications built around a 48V DC requirement, so it is the better fit when the system is designed for that voltage class rather than 12V or 24V. The correct choice still depends on matching the product's output voltage and available current to the load.
Will the ADS-15548 operate from common AC mains ranges?
Yes. The product data lists an AC input range of 88-264VAC, so the ADS-15548 can operate from common 120V and 240V AC mains systems within that range. That helps simplify use across different facilities and regions.
Is the ADS-15548 suitable for exposed outdoor installation?
The current product data does not list a waterproof IP rating, so the ADS-15548 should be treated as an indoor or enclosure-mounted power supply rather than a directly exposed outdoor unit. Its working temperature is listed as -10°C to +60°C with derating per the datasheet curve (full load needs 21.6CFM forced air), and the final enclosure still needs to match the environment.
How does the ADS-15548 compare with the rest of the ADS family?
The ADS-15548 delivers 154.2W at 48V and 2.9A on the main output. In the same ADS-155 series, the ADS-15512 provides 153W at 12V and 11.5A, and the ADS-15524 provides 154.2W at 24V and 5.8A, all with the same 5V 3A auxiliary output. The main difference is the output voltage class and the available current at that voltage.
