Frequently Asked Questions
Can the EPS-45-3.3-C be used for 3.3V industrial I/O or communications electronics?
Yes, it is a constant voltage 3.3V supply rated for up to 8A and 26.4W, which suits many low-voltage industrial electronics that require 3.3VDC. The input side accepts 90-264VAC, so it is intended for AC-fed equipment.
Is this model appropriate for embedded processor boards and digital control hardware?
It is appropriate when the hardware is designed for 3.3V constant voltage input and the total load remains within 26.4W and 8A. This makes it relevant for embedded control assemblies where 3.3V is the required rail.
Can I use the EPS-45-3.3-C for several 3.3V modules in the same enclosure?
It can support multiple 3.3V modules as long as their combined demand stays at or below 8A and 26.4W. Buyers should size the total 3.3V load against both the current and power limits, not voltage alone.
Will the EPS-45-3.3-C handle cold or warm indoor equipment conditions?
The specified operating range is -30°C to +70°C, so it is built for a broad span of indoor equipment temperatures. Since no IP rating is listed, it should not be assumed suitable for direct outdoor exposure or wet environments.
What 3.3V choices are available around the EPS-45-3.3-C in the EPS family?
The listed 3.3V siblings 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 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. This unit shares the same 26.4W, 3.3V, 8A rating as EPS-45-3.3 and EPS-45S-3.3.
