Just stick to the point.
Two members here have expressed doubt about your claim.Don't you see it is in itself trollish in the present context?
Two members here have expressed doubt about your claim.
Why don't you explain your reasoning for making it?
Post #14 is a statement. Not an explanation.I already explained my reasoning in post #14.
An email to the people who's business it is to sell the kit?Since the members expressed doubt,I sent a email to the concerned company to explain themselves.
Fine. Please explain without further prevarication.But if you want me to explore more based on my own technical knowledge,I am ready.
Let us refrain from snap judgments,
A UPS may be fed from a power conditioner to enhance the battery life.
Except maybe this from post #14?
All I'm asking is for you provide a basis for that claim you, yourself already made.
If you can't, that's fine.
Just say so.
Read link in post#14.Therein lies the basis for my proposal.
Typical Factory ConfigurationThe AVC2 protects UPS operation and gives extended battery life.

Just remember, when you do, that their business is to sell their product.I quit from this thread till I get some information from that company.
I don't see how this is possible. The one of the purposes of a UPS is to take cruddy power and deliver clean. The batteries aren't involved unless there isn't enough energy coming in to make the energy going out (+overhead). Are you/they suggesting that by removing momentary draws on the batteries the life is improved measurable? How much?
This doesn't pass the sniff test here. Can someone else explain?
A UPS is not a device to clean power, unless additional components are added.
So long as there is power, the power goes through a transfer relay to the output of the UPS, taking the UPS out of the power circuit. Any 'crud' will just pass through the relay to the output, so long as the transfer relay remains closed on the POCO side. When power drops, the transfer relay opens on the POCO side, switching over to the position that delivers power from a battery fed inverter.
Some units are built with power conditioners, and some units are isolated, meaning the inverters are always the source of the output power and the POCO feed is cut down to the voltage required to charge the batteries. Those will provide some protection, but those features are not required for simple uninterrupted power.
There is some efficiency issues with isolated UPS devices that need to be considered due to the efficiency of the inverters, which will be on all the time, vs. a standard UPS in which the inverters only are used during an outage.
I was trying to remember the proper terminology for the UPS systems. I knew there are some that are straight through devices that more or less have an electronic version of a transfer switch. I think they transfer in about a 1/4 wave.
But then again, this place is a sewage or wastewater plant. I don't see it as having a serious percentage of it's load as computerized. And I really doubt it has PQ issues to begin with.
Maybe, maybe, maybe if there are a lot of pumps running on poorly designed VFDs.
I really think the engineer that got sold on this has egg all over his face.
BTW, I consider banging up salesmen who sell stuff like this as sport lol. I put them in the same category as the people selling PF correction devices for homeowners.
Hey K8MHZ,
Isn't there another UPS that runs as isolated, but should there be a problem they switch to straight through? Or is that pretty much all "isolated UPS" designs?
