Frequently Asked Questions
Can I use the EPS-45-3.3 to power 3.3V logic boards or embedded controllers?
Yes, this model is designed for constant voltage 3.3V output and can deliver up to 8A, with a total power rating of 26.4W. That makes it relevant for embedded and digital electronics that require a regulated 3.3VDC source from a 90-264VAC input.
Is the EPS-45-3.3 suitable for FPGA, MCU, or industrial communication boards that run on 3.3V?
It can be used for 3.3V industrial and embedded boards when their combined demand stays within 26.4W and 8A. The key fit point is that the load must be specified for constant voltage 3.3V operation.
Can this power supply support multiple 3.3V control modules in one system?
It can, provided the total current draw of all 3.3V modules does not exceed 8A and the total output power does not exceed 26.4W. For AC-fed cabinets or equipment, the 90-264VAC input range gives flexibility on the supply side.
Is the EPS-45-3.3 meant for indoor electronics rather than outdoor exposed use?
The published operating temperature range is -30°C to +70°C, which supports a wide range of equipment-room and enclosure conditions. No IP rating is listed, so it should not be treated as an outdoor-exposed or sealed-enclosure power supply by itself.
How does the EPS-45-3.3 compare with other 3.3V EPS models?
In the sibling list, the 3.3V models are EPS-15-3.3 at 9.9W and 3A, EPS-25-3.3 at 16.5W and 5A, EPS-35-3.3 at 19.8W and 6A, EPS-45-3.3-C at 26.4W and 8A, EPS-45S-3.3 at 26.4W and 8A, EPS-65-3.3 and EPS-65-3.3-C at 36.3W and 11A, and EPS-65S-3.3 at 33W and 10A. The EPS-45-3.3 sits between the 35W-class and 65W-class 3.3V options at 26.4W and 8A.
