Test conditions and notes10
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Peak current or peak power up to 3 seconds is provided.
- 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 4. Tolerance : includes set up tolerance, line regulation and load regulation.
- 5. Line regulation is measured from low line to high line at rated load.
- 6. Load regulation is measured from 0% to 100% rated load.
- 7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
- 8. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 9. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the 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 )
- 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).

FAQ
What is the output rating of the Mean Well ENP-180-48?
The ENP-180-48 is a 180W-class desktop power supply (182W rated) with a 55.2V output at 3.3A. It is designed for applications that need a higher DC output voltage with a compact external form factor.
Is the ENP-180-48 energy efficient for commercial or OEM use?
Yes. This model meets Energy Efficiency Level VI and has no-load power consumption below 0.15W. Its typical efficiency is 94%, which is useful for energy-conscious equipment designs.
What protections are built into the ENP-180-48?
The ENP-180-48 includes short circuit, overload, over-voltage, and over-temperature protection. Its overload behavior supports 110% to 125% of rated output power for more than 3 seconds before shifting to constant-current limiting, with auto-recovery after the condition is removed.
Can the ENP-180-48 operate in demanding temperature conditions?
This model has a specified operating temperature range of -30°C to +70°C. Output derating applies at higher ambient temperatures, so check the derating curve on the datasheet when planning operation near the upper limit.
What types of equipment is the ENP-180-48 suitable for?
The ENP-180-48 is suited to equipment that requires a regulated 55.2V DC output from a desktop-style external power supply. B2B buyers commonly consider this format for industrial, commercial, and battery-charging-related applications where efficiency, protection features, and a Level VI external supply are important.
What input range and compliance standards does the ENP-180-48 support?
This unit accepts a universal input range of 90 to 264VAC or 127 to 370VDC and includes active PFC. It is approved to IEC62368-1, UL62368-1, and EAC TP TC 004, and meets BS EN/EN62368-1 along with listed EMC standards including EN55032 Class B.
What are the physical size and warranty for the ENP-180-48?
The enclosure measures 192 x 178 x 45.5 mm and the product weight is listed as 1.15 kg. The datasheet does not state a warranty period, so please confirm warranty terms at the time of purchase.
