Frequently Asked Questions
Can I use the EPS-45-48 for a 48V industrial control or monitoring device?
Yes, if the device is designed for 48V constant-voltage input and draws no more than 1A. This supply provides up to 48W, which fits lower-power industrial control, monitoring, and interface equipment built around a 48V DC bus.
Is the EPS-45-48 suitable for small 48V telecom or network-support equipment?
It can be a fit for 48V telecom or network-support loads that need constant voltage and stay within 48W. The output limit is 1A, so it is best for lighter-duty 48V equipment rather than higher-draw systems.
Can this power a 48V embedded development or validation setup?
Yes, for embedded platforms, validation fixtures, or lab assemblies that require a stable 48V constant-voltage supply up to 1A. The 90-264VAC input is also useful when the same setup may be used on different AC input ranges.
Would the EPS-45-48 work for a compact 48V automation node?
Yes, if the automation node uses 48V DC and its load stays within 48W total. The smaller 101.6 × 50.8 × 29.0 mm form factor and 0.14 kg weight make it practical where space and weight matter.
Can the EPS-45-48 be used in outdoor or high-temperature locations?
The operating temperature range is -30°C to +70°C, so the temperature spec is broad. However, no IP rating is listed, so the published specs support indoor or otherwise protected use rather than direct outdoor exposure.
