Difference between Back-UPS & Back-UPS PRO

This was originally posted on APC forums on 7/3/2017


Hi. I'm trying to figure out what UPS is best for my setup which basically consists of my PC computer (tower + 23'' lcd monitor) + a pair of active studio monitors (speakers, these are the delicate part of the setup and the reason I'm getting the UPS).

Really all I need to know is the difference in features between those two families of UPS, since I'm trying to get the best in terms of performance that I can that will protect the speakers in case of surges or spikes as well as under or over voltage. Specifically the models I'm looking at are the BR900G vs the BX1100CI, which I can get at the same price. Both accommodate the total power draw perfectly, but I prefer quality and performance over things like autonomy, or overhead for future additions to the system.

Any insight is greatly appreciated.

Tomas

Thank you for your answer.

I would actually recommend that you look at a Smart-UPS model. The inverter circuit used in the Back-UPS and Back-UPS pro may cause your speakers to buzz or produce other undesirable sounds.

Yeah, that was my main concern, unfortunately the smart ups are out of my budget. I suppose the best answer is to get the back-UPS Pro and keep the speakers connected to the 'surge only' outlets (the non-pro models have no separate surge only outlets, only battery), that way they will still be protected but won't be getting the square wave from the battery. Do you think that should work or am I missing something?

For the current Back-UPS and Back-UPS Pro product line, I don't believe there is much difference beyond what gets printed on the front panel. (The Back-UPS Pro may add the ability to regulate both high and low line voltage, and may also provide for simple signaling over an RS-232 serial port as compared to the regular Back-UPS. I'm not 100% sure. Here in the US we don't have anything like the BX1100CI design.)

Since you mentioned a desire to have the best protection for your monitor speakers, I would actually recommend that you look at a Smart-UPS model. The inverter circuit used in the Back-UPS and Back-UPS pro may cause your speakers to buzz or produce other undesirable sounds. Damage to the speakers would be very unlikely. The 750 VA and larger Smart-UPS products have a true sine wave inverter whose output is of very high quality and would match exactly what you get from your electrical utility.
