Frequently Asked Questions
Can I use the EPP-120S-48 for 48V telecom or network equipment?
Yes, if the equipment is designed for constant 48V DC input and stays within 2.5A and 120W. That makes it more appropriate for lighter 48V loads than higher-current 48V systems.
Is this power supply a good fit for 48V industrial automation devices?
It can work well for automation hardware that requires a constant 48V supply rather than 12V, 24V, or 27V. The output is limited to 48V at 2.5A, so load sizing is the main compatibility check.
Can the EPP-120S-48 power embedded systems that run on a 48V DC bus?
Yes, for embedded or OEM equipment built around a 48V constant-voltage bus and drawing no more than 120W. Its compact 76.2 × 50.8 × 28.0 mm footprint also helps where enclosure space is tight.
How should I size a 48V load for this model?
This unit supplies 48V DC up to 2.5A, with a total power limit of 120W. If the application needs more than 2.5A at 48V, a higher-output sibling would be the better match.
Can I use the EPP-120S-48 in outdoor equipment?
The operating temperature range is -30°C to +85°C, but no IP rating is listed in the product specs. That points to use in protected indoor enclosures rather than direct outdoor exposure.
