Test conditions and notes6
- 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. 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 720mm*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)
- 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).
- 6. This power supply does not meet the harmonic current requirements outlined by EN61000-3-2. Please do not use this power supply under the following conditions: a) the end-devices is used within the European Union, and b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal voltage, and c) the power supply is: - installed in end-devices with average or continuous input power greater than 75W, or - belong to part of a lighting system Exception: Power supplies used within the following end-devices do not need to fulfill EN61000-3-2 a) professional equipment with a total rated input power greater than 1000W; b) symmetrically controlled heating elements with a rated power less than or equal to 200W

FAQ
Can I use the SE-1500-48 for 48V industrial networking or telecom equipment?
Yes, if the equipment is designed for a constant-voltage 48V DC input, this supply is in the right class. It provides 48V output at up to 31.3A with a total rating of 1502.4W.
Is the SE-1500-48 suitable for a 48V automation or control power bus?
It can be used where a system is built around a regulated 48V DC bus and needs higher centralized power. The rated output is 31.3A at 48V, with 1502.4W available.
Can this power supply support a 48V embedded or communications rack?
It is appropriate for embedded, communications, or industrial rack systems that require constant-voltage 48V input. The supply's published capacity is 31.3A and 1502.4W, so the total rack load has to stay within that limit.
Is the SE-1500-48 suitable for outdoor cabinets?
The listed specifications do not include an IP rating, so the product data does not establish outdoor or weather-exposed use. It is rated to operate from -20°C to +70°C, but that temperature range does not define ingress protection.
What is different about the SE-1500-48 versus the other SE-1500 versions?
The SE-1500 family shown here includes 5V 300A 1500W, 12V 125A 1500W, 15V 100A 1500W, 24V 62.5A 1500W, 27V 55.6A 1501.2W, and 48V 31.3A 1502.4W models. The SE-1500-48 is the highest-voltage version in that group and has the lowest listed output current at 31.3A.
