Frequently Asked Questions
Can I use the EPP-400-27 for a 27V industrial controller or HMI load?
Yes, this model is a constant voltage 27V power supply rated for 9.3A and 251.1W. It fits 27V control or interface equipment when the total load stays within those output limits.
Is the EPP-400-27 suitable for a 27V embedded system with multiple powered boards?
It can be a fit for a 27V embedded platform that needs a regulated constant voltage source and draws no more than 9.3A. The available 251.1W gives more headroom than lower-power 27V models in the same family.
Can this 27V power supply be used in factory automation equipment with universal AC input?
It is designed for 80-264VAC input, so it suits automation equipment that may be used across different AC mains ranges. On the output side, it provides 27V constant voltage up to 9.3A and 251.1W.
How does the EPP-400-27 compare with other Mean Well EPP series models?
Within the EPP family, 27V options are EPP-100-27 at 75.6W and 2.8A, EPP-120S-27 at 119.9W and 4.44A, EPP-150-27 at 100.17W and 3.71A, EPP-200-27 at 143.1W and 5.3A, EPP-300-27 at 199.8W and 7.4A, EPP-400-27 at 251.1W and 9.3A, and EPP-500-27 at 321.3W and 11.9A. Other family outputs include 12V models from 75.6W to 320.4W, 15V models from 75W to 319.5W, 18V models at 250.5W and 320.4W, 24V models from 76.8W to 321W, 36V models at 252W and 320.4W, 48V models from 76.8W to 321.6W, and a 54V model at 320.2W.
Is the EPP-400-27 appropriate for outdoor or harsh-temperature use?
The operating temperature range is -30°C to +70°C, so it covers a wide temperature span. No IP rating is listed in the provided specs, so the product data does not describe it as weatherproof or outdoor-rated.
