Frequently Asked Questions
Can I use the EPS-15-3.3 for a 3.3V control board or embedded controller?
Yes, this is a constant voltage 3.3V power supply rated for up to 3A and 9.9W. It fits embedded or industrial control electronics that require a regulated 3.3V rail and stay within that 3A output limit.
Is this power supply suitable for 3.3V sensors or low-power automation electronics?
It can be a fit for 3.3V automation electronics when the total load stays within 9.9W and 3A. The wide 85-264VAC input also makes it practical for equipment that may be deployed across different AC mains ranges.
Can I use this in a compact industrial or IT enclosure?
Yes, the board measures 63.5 x 45.7 x 24.0 mm and weighs 0.057 kg, so it is sized for compact internal equipment layouts. It is best matched to enclosed devices that need a 3.3V constant voltage supply rather than higher-voltage loads.
Will the EPS-15-3.3 work for small 3.3V logic or interface modules in automation equipment?
Yes, it is intended for low-power 3.3V loads and provides up to 3A from a constant voltage output. That makes it suitable for logic, interface, and controller modules that need 3.3V and do not exceed 9.9W.
Is the EPS-15-3.3 suitable for outdoor or harsh-temperature locations?
The published operating temperature range is -30C to +70C, so it covers a broad temperature span for installed equipment. No IP rating is listed in the provided specs, so outdoor or washdown suitability is not established here and it is better evaluated as an internal power supply for protected enclosures.
How does the EPS-15-3.3 compare with the other 3.3V EPS models?
Within the 3.3V EPS range, the EPS-15-3.3 is 9.9W at 3A, the EPS-25-3.3 is 16.5W at 5A, the EPS-35-3.3 is 19.8W at 6A, the EPS-45-3.3 and EPS-45-3.3-C are 26.4W at 8A, the EPS-45S-3.3 is 26.4W at 8A, the EPS-65-3.3 and EPS-65-3.3-C are 36.3W at 11A, and the EPS-65S-3.3 is 33W at 10A. The main difference is available output power and current at the same 3.3V output.
