[AFMUG] Sitemonitor question - different voltages

[Paul McCall]

Can the sitemonitor have two different voltages on the 2 inputs that it 
monitors / powers from?

We have a lot of them setup in the field with a 110vac – 24v wall wart to 
monitor commercial power.  And, the 2nd input is off the 24v battery array. 
Batteries are all 48v now, so wondering if I need to buy a bunch of similar 48v 
wall warts or whether the SiteMonitor can deal with the 2 different voltages 
and I don’t need to buy anything 😊

Yes - it can accept multiple voltages on PWR1 and PWR2.

[Josh Luthman]

That's exactly what we use it for.  Volts1 is utility (we use some random
wall wart) and volts2 is the battery.

[Bill Prince]

We use inputs from 12V to 56V as long as it's a Base II; mix and match. 
They all have to be negative ground too.

Re: [AFMUG] Sitemonitor question - different voltages

[George Skorup]

Be careful connecting +48VDC to a SiteMonitor. Verify it's a Base-II 
first. The old Base-I's are limited to 30 or 32VDC on both inputs.


I typically connect the pwr1 input to my main rail, usually 24-28VDC so 
it's safe for Base-I's or Base-II's. I've been recycling a lot of old 
Base-I's from site rebuilds the last year or so. Pwr2 gets the wall 
brick for utility monitoring. I try to dig out old SyncPipe power 
supplies if I can find them because they're linear. We're at many towers 
with crappy power, or those 3-phase sites that lose a phase and we end 
up with <100VAC and our UPS transfers to battery. Most switching bricks 
will operate down to 80-85VAC. Has happened more times that I can 
remember. Site goes down because the batteries ran down, yet we never 
got a utility power alarm. The linear brick lets you see the voltage 
situation. Problem is, they're getting pretty hard to find now.

Of course.  You'll also be able to monitor both at the same time.

Conversely an RB750 will only report the highest of the two voltages.

Re: [AFMUG] Sitemonitor question - different voltages

[Adam Moffett]

I think it draws current from whichever port has the higher voltage.
If you did +24 and -48 I bet that would be bad.

Yup, it works fine to mix... pwr1 and pwr2 definitely don't both have to be
the same. We typically have 24v on one and 48v on the other, on sites where
we're using both.

Re: [AFMUG] Sitemonitor question - different voltages

[D. Ryan Spott]

I have 2 differ t voltages on mine. 

On a 24VDC site I have Up to 31VDC on one input. It powers the unit and I 
monitor the sites status with it. 

Power supply 2 is a wall watt plugged into my remote genset. When the genset 
comes on I get 24.3VDC on that power input. This tells me the genset is 
running.

[Josh Luthman]

It works from like 6-56 volts.  -48 is a ways away from that...
