I have used Mean Well HRP-100-48 for that application, in outdoor NEMA boxes, with good results. I like to spec the power a little over what is actually needed, but there is a 75 watt version as well. It is super reliable model with 105*C capacitors and no fans, might be overkill for an indoor application, but they don’t cost that much more.

Looking for recommendations on a -48 vDC power supply. 1.5 amps. Not expected to have any other radios on site or would at least be independent. No batteries or anything. ===== During the final installation, protect the ODU by a magneto-thermal switch (not supplied with the equipment), whose characteristics must comply with the laws in force in one’s country. The typical magneto thermal switch has characteristics at least 48Vdc @1.5A with overcurrent relay class “C” or “K” tripping curve. ===== I'm finding things with long lead times, things at a much higher amperage capacity or things that will require wire nuts to complete. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com
