Will 12-250-dc really do 9 volts?

I'm thinking about cutting the LVD/regulator out of a DC box. This means the batteries go straight (through a relay) to the WS. Sites are usually <50 watts (Mostly AF5x + Epmp) so I have to assume that the 250 watt unit will safely do the "150 watts under 11 volts".

Should I be worried about anything or is this another situation of the WS just being amazing?

I don't care about the lifetime of my batteries. I want the tower equipment to powered.

If you have multiple batteries why not hook them in series?
Yes it will run on 9V but I think the budget is 100 or 150 watts at 9V.
I asked Dave to comment as I keep forgetting the volt budgets.

According to the chart Chris handed me yesterday, 150w available at 9v. (at room temperature)


We really do recommend powering these with 24v, though.

EDIT:: one caveat is the power supply will not turn on until a minimum of 10 volts is applied. At that point it will continue to operate down to 9v.

Beautiful. I figure 24vdc is easier to get to 50 (or whatever the regulator does inside) so that makes sense why you'd recommend 24v. It's also easier for me to always do 24vdc at sites.

I really doubt we'll lose power long enough to drop down to 9v but it's worth asking now and knowing in advance. If my 12v battery is putting out 4.5v it's pretty much toast anyway.

Love the product and love the support, thanks guys.

150 watts per the product page - https://www.netonix.com/ws-12-250-dc.html

250 Watt POE budget when input voltage is reater than 12V
200 Watt POE budget when input voltage is between 11V and 12V input
150 Watt POE budget when input voltage is below 11V
