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. :: // Shawn Peppers :: // DirectlinkAdmin.com > On Mar 21, 2018, at 4:04 PM, Kees H. <wispau...@calbb.net> wrote: > > Do you have a model# handy? > > > From: Shawn C.
