Product Page

The mothership (amazon) has this for 64.95 with free shipping.

Not to mention the benefit of picking which UPS you want from a selection of products.

I wish if one were plucked off of the mothersite, there would be a discount.

Need a link, since I can’t find it at Amazon.
This looks like a discontinued model, per Home Depot, New Egg, Walmart.

Dell has it for $74.99

600VA is $65 on AZN, while the 825VA (offered here) is $79. Still only a savings of $9 for a discontinued product (including shipping).

Y’all are still confusing me, since I don’t see a sine-wave model at those prices and those levels at Amazon. Links please. I see other model lines with different prices.

Good eye. I searched the model, and other models came up. Failed to notice it was another model, and matched the price.

Yeah. Not impulse buy range.

I definitely need 2 or 3 UPSes at the moment. Just not sure what I want.

Any more info on sine wave model?

I replied above - I thought I was seeing the model I searched for (LE825DG) but in actuality other models came up.

Is sine wave model what I’m after if I’m worried about rapidly fluctuating power changes during electrical storms? (not enough to turn off equipment, but enough to screw them up).

Fyi, the manufacturers web page says it’s

  • discontinued
  • 825VA (volt amps)/450W (watts).

In my searching, perhaps on the page above, I read that the Simulated Sine Wave (or Modulated Pulse) helps with the brownouts & spikes and that it’s good for

(emphasis added). So thus is no good for dedicate equipment that needs a SINE Wave. Why the feature called a simulated sine then idk other than for trickery.
Ok, good bye.

tl; dr: This is NOT the good sauce

See, here’s the thing; there are PURE sine-wave inverters (the good ones) and MODIFIED sine-wave inverters (the usually-okay ones but not suitable for all uses).

I assume “Simulated” is a marketing term that has been seen close enough to “modified” by the lawyers as to allow them to consciously mislead consumers.

FYI on pure sine wave vs. simulated sine wave

What I’d like to know is how much juice I can expect to get out of the battery during any given outage (mainly, can it keep my router alive so my VOIP phone can still work), and how long the battery is good for (how soon would I have to replace this thing)?

It is on that page. Scroll down. That feature not about brownouts or spikes, just, well, nothing actually…
Now, really :

Rootnull - AC electronics require a sine wave (that’s what AC is).

Not sure what you mean.

The model being sold by Woot here will not be good for most modern computers. High-efficiency power supplies use something called “active power-factor correction” (of active PFC) to achieve that 80%+ efficiency rating. Unfortunately active PFC means that sine waves which deviate from “true” sine waves by more than 10% will often damage the power supply. I had a computer which caught fire about a two years into its lifetime due to using a “simulated sine-wave” uninterruptable power supply like this one.

I normally stick with models that have “pure sine wave” like this one:
Cheaper model here:

You’ll note that the model I linked to is also doing something which isn’t quite perfect (they call it “Adaptive Sinewave”), but the important part is that the distortion of the output sine wave is less than 10%, and your power company only guarantees 10% anyway so that’s what all your equipment is designed to handle!

I don’t know if the model will handle brownouts well, but the specs section seems to imply it will:

I have the 1500VA model I linked to earlier and it definitely deals well with brownouts/quick flickers of power!

Most of the spec page for this product (that was linked to earlier) talks about the same features, and claims this unit is good for these events (brownouts among them)

Just an FYI, Simulated Sine = Modified Square Wave Form. This kind of power Can cause irregular operation on highly sensitive equipment

calling it a simulated sine wave is quite mis-leading.

thanks, y’all. that’s why I like it when I can come back here occasionally. you teach me stuff I don’t know.
