Maybe Michal Soltys has some additional insight into these models, but my first guess is that they are old enough (pre-2009) to work with the 'apcsmart' driver, and they should support normal low-battery shutdowns:

One way to do power control with your existing UPS is to add a Power Distribution Unit (PDU). NUT supports several:
It's difficult for us to recommend specific UPS models, since it seems like every time we find a good one, the manufacturer changes hardware under the hood (using the same model number), or they change to a new, incompatible proprietary protocol (APC did this in ~2009 with their Microlink protocol). My recommendation is to buy from a distributor with a good return policy.
