Test conditions and notes7
- 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 6. Heat Sink HS1,HS2 can not be shorted.
- 7. 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
Can I use the EPP-300-27 for equipment that specifically requires 27V DC?
Yes, if the load is designed for constant 27Vdc input and does not exceed 199.8W or 7.4A with convection cooling, or 300.24W or 11.12A with 20.5CFM airflow. This unit should be matched to equipment that explicitly calls for 27V rather than nearby DC voltages.
Is the EPP-300-27 suitable for 27V industrial control or embedded subsystems?
It can be used for 27Vdc control or embedded loads when the total requirement stays within 7.4A and 199.8W with convection cooling (11.12A and 300.24W with 20.5CFM airflow). The 90-264VAC input range can also help in mixed-site industrial deployments.
Can this power supply run a 27V instrumentation or test fixture load?
It is appropriate for 27V instrumentation, fixtures, or specialty electronics that need a constant-voltage output and stay under 199.8W convection-cooled or 300.24W with 20.5CFM airflow. The 27V output (adjustable 25.65-28.35V) is the key compatibility point, with current capacity up to 7.4A, or 11.12A with forced air.
Is the EPP-300-27 rated for outdoor service?
The unit is specified for operation from -30 degrees C to +70 degrees C, with output derating at higher temperatures per the derating curve. However, the provided specs do not list an IP rating, so they do not confirm outdoor, wet-location, or dust-exposed suitability.
