Power Supplies


Darryl J Kelly
 

I have been running two Meanwell LRS-350-15's for over a year with no
problems. Also run two Superlight LH-350W. Cost of the Meanwells are
about $40 and the Superlights $20, four 30 amp supplies for about
$120. No noise and problems that I am aware of, fans almost never come
on.

The question is....if they were very RF noisy, would you know?  Have you checked?

Many switching supplies DO NOT have crowbar protection.  A friend lost his HF rig (not economical to repair) after his MFJ switcher zapped it with the unregulated Voltage.  Repeaterbuilder.com has numerous articles on the subject, mostly about Astron supplies.  They are worth reading.  Your gear is worth protecting!
