Nice Apex Power Backup Opportunity

gotcha..just have to ensure that your internet provider will be running during the black out.

I just ordered two of these power supply... one apex and the other for my Aquacontroller III pro.

Yes, that is key, hence the need for 4 of these for me. The large routers/switches I use will only last a short time but for average users, these will allow you to watch your tank go cold.

l need to build a DIY forum thread for detailed documentation on this build. But for those who want to do their own research... here you go.

My Cisco 5 port switch/ethernet bridge will draw a maximum of 2A at 5v. So I needed to go to my local Fry's Electronics (google them for shipping) and get an NTE 5 volt voltage regulator. Part # NTE1934. Then I needed a simple 47microfarad capacitor and I added a diode for polararity insurance. Finally a project box with pcb and some dc power jacks. Total spent was about $40, a lot incomparision to the 4 ups I got off ebay for $40 shipped.

If you google nte1934 there is a design .pdf document which nte puts out. It has a wiring diagram to give you what you need, but again here is a simple verison.


On the pcb install the regulator, pin 1(left looking at identification marks) is +5 VDC out. Pin 2(center) is +12 VDC input. Pin 3 is ground(right looking at identification marks.)

Wiring the capacitor across across 1 to 3 minding polarity and the diode across 1 to 2 minding polarity you are almost there.

I drilled a few 1/2" holes in the sides of the project box and installed the DC power jacks. A single 12VDC(input) on one side and a 12VDC(output) and 5VDC(output) on the other.

Connect all the gournds, connect VDC in and out and viola.

I'm traveling for a while, but drop me a pm for questions. Please if you have no idea how to proceed, be patient and wait for a DIY forum post.

If you are in the USA, there was a standard for 8 hours of battery backup for lan line offices(they usually lasted up to 4 hours.)

This lan line battery or generator backup will usually give you enought time, to match your UPS backup for you to get a MAYDAY message to your email to let you get home ASAP. Meanwhile your other UPS is keeping your powerheads going.

If more than your local lan office has a power outage, I'd imagine it would be in the news or you would know as this would be a very large outage.

Good luck, but by no means is this fool proof to power outages. Get a sugar momma/daddy to beat a power outage....

does that standard 8 hours apply for residential lines?

OT:One last tidbit;

***Don't use a cable comany to provide phone or internet service***

They are even worse than lan line companies, almost no battery backup in power outage events. You'll be S.O.L.

It did. Resendtial telephone lines provided by the origianl 7 Bell Company; ATT, southwest bell, uswest, and others companies all had the same standards. They still usually have some battery backup.
