Only gotchas with these, you have to be careful not to exceed the output 
over-volt protection voltage or they will shut down and not come back on unless 
power cycled.  This would potentially happen if you had a lot of devices on 
tower and you where running the voltage adjustment very high.  This is a 
protection feature of the power supply to protect your equipment in the event 
something drawing a lot of amperage on the output circuit all the sudden dies.  
This sudden event would cause the voltage to increase and could potentially fry 
a sensitive piece of equipment.

    Why in the world would you not want to hit the thing with exactly 50 volts? 
 Get a variable voltage output power supply and once your under load then 
adjust respectfully.  Meanwell makes a $50 power supply that does this....the 
older versions where not defective technically....its just no one knew how to 
properly power the device and properly account for voltage drops.

      fyi the early versions (up until just recently) the input voltage range 
did not match the spec. The newer date codes match the spec. I cannot remember 
exactly but I think the early ones cut off at about 45-46v while the fixed 
models are about 39?

        I use this exact setup on all my FM towers.  Works awesome...although i
        still put them in a metal enclosure and put the cat5 in MC up on tower.
