Fsp Fp series and off-mode charging feature

by Katmai6 / November 16, 2017 4:09 PM PST

I am thinking about buying a ups from Fsp Fp series.The thing I notice when I look at it's features, it is written:

"Off-mode charging"

Does it mean that it can charge itself even when it's in off-mode( in addition to be able to charge itself while in on-mode/running) or it can charge itself only when it's in off-mode/turned off?

Also what do you think about Fsp ups products,are they reliable?(I want to ask especially to people who are using or have used an Fsp ups).

No sale? But why?

If a maker or seller does not give pre-sales answers it's a bad sign. Also FSP is https://en.wikipedia.org/wiki/FSP_Group or a group of names we know for low cost only seems to be mid to low quality power supplies.

Let's see that model so we can read the manual about this.

I should ask for that since https://www.google.com/search?q=Fsp+Fp+600 didn't show one model.

I'll read http://www.fsplifestyle.com/PROP161000125/ since it's the first hit that noted off-mode.

There is no manual. That's strange. On to their other site.
http://fsp-europe.com/download/ finds the manual. I get the feeling I'm reading something from Douglas Adams about the plans were clearly on display at the bottom of the stairs behind the door marked "beware of the Leopard."

Sure enough the product manual omitted definition.

Let's see what another maker defines as off-mode charging. This from APC:

"The UPS will charge when powered off when connected to AC source."

So while FPS failed to supply the answer I think they need to fix this omission.
I don't work for them but as an Electronics Designer, I think this would be fairly easy to test.

Thanks for your answer. I noticed I got a reply from Fsp to my email.They say the unit recharges itself both in off-mode and running.

So I think Apc means that their model charges only when powered off and connected to AC source?

As to your APC question.
by R. Proffitt Forum moderator / November 17, 2017 12:24 PM PST

I think we have to think for ourselves on this one. If there is no AC source, how can it charge?

"I think we have to think for ourselves on this one. If there is no AC source, how can it charge?"

In APC case, I meant if the Apc unit is turned off but connected to AC source, it recharges but if the APC unit is turned on and connected to AC source, it can't recharge?

To determine that.

It's on a model by model check. But no unit I've seen today does not pass up a chance to charge when AC is present. Now what is ON and OFF?

I think we are dwelling too long on this. Every UPS we ever deployed was never turned off. We plugged it into the mains, turned it on and plugged in the gear that needed to not lose power. We never thought about them again for years.

I used to deploy UPS's at the office.

But we don't today. Why? The fleet is all laptops which means no reason to duplicate what a laptop offers.

As to which, I don't know your criteria, price or why you would choose one over another.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
