Yes, we have moved to the Netonix to power all POE in the cabinet. Makes things really simple, but there is a limited amount of wattage you can get out of it. We use the 250 Watt model, which is more than double what we need, but then you can power all 24V and all 48V from that and have the ability to control power to any port individually so that you can power cycle any device hooked to it. Works really well, but probably more for lower wattage installations, however I see you can get them up to 500 Watts. Our biggest thing was to reduce the amount of stuff in the cabinet and reduce the cost. The big ticket item is the Netonix, so it doesn’t help with cost reduction as much, but really reduces clutter. We are fitting the two Meanwells, the Tycon TPDIN, Netonix, Mikrotik Router, two batteries, a fan and a heater inside a 20x16x8 inch cabinet. Biggest issue is all the wires running to the TPDIN to monitor voltage, current, and Relays for the Fan, Heater and Netonix.

If we do need 24V for whatever reason, we typically use a Netonix switch that can output 24V via PoE. What are you using on new sites that requires 24V?

Pretty much every site ends up needing both 48v and 24v anyway, so unless you do a complete DC plant for each voltage, you're going to end up needing some kind of a converter one way or the other anyhow, and that way you can do two batteries instead of four. Only problem being I haven't found a nice DIN rail 24v-48v converter (the meanwell one does the job fine, it's just not a proper DIN mount device). So the way I'm leaning for new sites is to do a nice big Meanwell DIN mount 24v power supply, with a DR-UPS and and a 24v to 48v DC converter, connected to two PacketFlux PDUs (one for 48v and one for 24v). That gives me five remotely controllable power outputs for each voltage that I can use to power whatever routers, switches, PoE injectors, or whatever I need. And there are contacts on those power supplies that can be connected to the Packetflux Base for monitoring purposes. Might be able to do things a bit more cleanly with a Rackinjector too... I haven't had time to play with that much yet though.

For small-ish sites, we have been running a Meanwell/Traco hybrid using the SDR-240-48 and a Traco TSP-BCM48A or BCMU360.

The DR-UPS can do 40amp on 24v, so your upper limit is almost 1kW. Just drive it with a bigger 24v supply as needed. What has held me back from that in the past is the DR-UPS is not available in 48v, and the biggest power consumers I have are 48V. I went to Traco to stay 48V. OTOH your rig is so much cheaper than Traco that adding an RSD-300B-48 for another $100 is not a bad deal. ------ Original Message ------ From: "David Coudron" <david.coud...@advantenon.com<mailto:david.coud...@advantenon.com>> To: "af@afmug.com<mailto:af@afmug.com>" <af@afmug.com<mailto:af@afmug.com>> Sent: 1/28/2018 10:39:56 PM Subject: Re: [AFMUG] Dc plant conversion Here is what we are doing, I think this is close to what Steve is asking for: Meanwell SDR-240-24 AC to DC power source: $84 Meanwell DR-UPS40 Battery Float/UPS: $37 Tycon TPDIN MonitorWeb2: $131 24 V of battery backup $70-120 depending on the runtime looking for Netonix 150 W or 250 DC switch: $250-350 (This is really the only expensive component) Heater: $65 Fan: $14 With this, we can run 5-8 hours on very small batteries, we figure we have several hours to get a generator to the site if power isn’t coming back. We run all POE from the Netonix, it works really well. Here are the other things we can do with the box: 1. Monitor temp in the cabinet 2. Monitor/alert on loss of AC line power through TP DIN 3. Monitor voltage of the batteries 4. Monitor voltage to the Netonix 5. Monitor Current to the Netonix 6. Monitor Current in/out of the batteries 7. Auto start the heater below 40 degrees 8. Auto start the fan above 80 degrees 9. Power cycle the netonix from the TP DIN 10. Power cycle any AP, Router, Backhaul from the Netonix We also put a Mikrotik router in this cabinet. Usually a Hex POE (for small sites) or a 3011 for larger sites. We have 13 in the field set up like this and are going 15 more right now. While it might be a little more than what you were thinking, it gives us a ton of control for pretty minimal investment per site. Best part is, no coding necessary. Doing all this with the Monitor Web2 settings and/or SNMP. Let me know if you are interested in pictures. For this second batch we have started using Terminal blocks to clean up the wiring, the cabinets look a little better, but we went to a smaller poly cabinet that makes things a little tight.

If I had to do it now I'd go with the IDC switch. When we did our design, the idc didn't exist so we just went down to 24V off of our A and B sides and run a redundant powered 24V bus which all the netonix switches run on. I better buy up another batch of Elteks before all y'all buy them all up. These are mostly decommissioned Sprint/Clearwire btw.

Id love you to do it out of the kindness of your heart, but i do have some advisory busget. Im just tired of the apc ups waste and super ghetto runtimes on batteries coupled with having to accept we are destroying runtimes by letting the apcs die..... please, somebody, please. Otherwise i have to go to the facebook groups, and thats like going to a mikrotik or ubnt forum.
