Frequently Asked Questions
Can I use the EPP-400-48 for a 48V industrial network or control system?
Yes, if the load requires constant 48V and stays within 5.3A. This unit is rated for 254.4W, making it suitable for higher-power 48V control and communications equipment.
Is the EPP-400-48 suitable for a 48V embedded or telecom-style DC bus?
It is a fit for systems built around a constant 48V bus when total demand does not exceed 5.3A. The available output power is 254.4W.
Can this model power a larger 48V automation assembly instead of a smaller EPP unit?
Yes, this version provides 48V at 5.3A and 254.4W, which is more output capacity than the lower-power 48V models in the same family. That makes it better suited to larger 48V loads than the 76.8W, 120W, 100.8W, 144W, or 200.2W 48V variants.
How does the EPP-400-48 compare with other EPP family choices?
The 48V versions listed are EPP-100-48 at 76.8W and 1.6A, EPP-120S-48 at 120W and 2.5A, EPP-150-48 at 100.8W and 2.1A, EPP-200-48 at 144W and 3A, EPP-300-48 at 200.2W and 4.17A, EPP-400-48 at 254.4W and 5.3A, and EPP-500-48 at 321.6W and 6.7A. The same family also includes 12V, 15V, 18V, 24V, 27V, 36V, and 54V outputs with power ratings ranging from 75W to 321.3W depending on the model.
Is the EPP-400-48 rated for outdoor use?
Its operating temperature range is -30°C to +70°C, so the temperature specification is broad. However, no IP rating is listed in the provided product data, so the specs do not describe it as an outdoor-rated power supply.
