these are the models we use PULS Power supplies. 24VDC power supplies 240Watt=10Amps QS10.241, 480Watt=20Amps QS20.241
48VDC power supplies 240Watt=5Amps QS10.481, 480Watt=10Amps QS20.481 good stuff...much better then I Don't Meanwell Jaime Solorza Wireless Systems Architect 915-861-1390 On Thu, Mar 10, 2016 at 8:06 AM, Josh Baird <[email protected]> wrote: > From PSUI: > > Traco TSP 360-148 (360w/48V) - $233 > Traco TSP-BCM48 - $126 > > Or, instead of the BCM48, you can use the: > > Traco TSP-BCMU360 (single 12V battery, selectable 24/48V output, less > charging current than the BCM48) for around the same price, I believe. > > Josh > > On Thu, Mar 10, 2016 at 9:57 AM, Gino Villarini <[email protected]> > wrote: > >> how much are you paying for this combo? >> >> On Wed, Mar 9, 2016 at 4:21 PM, George Skorup <[email protected]> wrote: >> >>> The AD-155 is 150W max load. >>> >>> What I would do is a Traco TSP 48v power supply (180, 240, 360 or 600W), >>> a TSP-BCMU360 in 48v mode and a Mean Well 48 to 24 RSD.
