SmartUPS 1500 - how to adjust LOWEST voltage allowed!!!

[Anonymous user]

I am using my APC SmartUPS 1500 SUA1500RM2U unit on my home theater system due to its AVR and wattage rating.

Here is the issue: My Amp is very voltage sensitive. When large devices in my home come on, it creates a hiccup in the sound (sound goes away for a fraction of a second and then returns).

Someone suggested that I configure the unit to be more strict with its lower voltage limit.

I got Powerchute Business Edition, but it will NOT let me up the lower voltage any higher than 106!

I am going to be very sad if there is nothing that can be done about this.

Any suggestions?

PS - I have dealt with a variety of electrical solutions, now I am on this last one.

If your equipment is that sensitive, the Smart-UPS product line may not be good enough for you. While they are line-interactive meaning they will compensate for high and low line voltage, they will only do that when voltage drops below 106 or goes above 127.

You may need a double-conversion UPS, such as the Smart-UPS RT series. As you may know, these always power the load through the inverter so you always get perfectly stable voltage to the load regardless of line voltage.

Stew - What would be a comparable RT model to the SmartUPS 1500 I have?

I don't mind if it is an older unit or not. In fact I would prefer an older unit that I can replace the batteries on etc.

The Smart-UPS RT 1500 looks to have similar VA ratings

I suppose ebay would be as good a place as any to look for used ones.

Thanks for your help and time!

I never knew about this voltage craziness.. 🙂
