I ran into a problem with one of these yesterday that makes me leery of using them again.
http://www.mouser.com/Search/ProductDetail.aspx?R=SD-25B-24virtualkey63430000virtualkey709-SD25B-24 If the amperage goes over the rated max (1.1A) it appears the unit continues to allow dc through, but does not regulate it any longer. So in my case, I had a well-charged battery powering a mikrotik rb450 as well as a couple Trango AP's (with the infamous heaters). When I plugged in the second AP on a cold day, it momentarily caused the draw to go higher than 1.1A. 28+ volts started flowing through the "regulator" and caused the RB450 to go into overvoltage protection mode (ie: dead in the water). Will be trying out the Tycon Power and the Packetflux devices shortly. If Mikrotik comes out with another Routerboard that has 28v overvoltage protection... What a waste.
