Quick take
When you're shopping for used UPS critical power monitoring hardware, the decision usually comes down to a specific model number and what you're willing to pay for a used unit. In this group, the listed price range runs from USD 49.29 to USD 249.99, and the four units fall into two part-number families: 102553-OA and 102198-0F. The MGE / VERIS 102553-OA system and the 102198-0F interface display open at the low end, while the MGE UPS Systems 102553-OA AK sits at the high end. A Z102198-0F system unit is priced close to the low end and gives you a different same-family part number.

Product notes
MGE / VERIS 102553-OA KMGM UPS Systems Critical Power Monitoring System

This is the lower-priced 102553-OA route in the group. The model number is 102553-OA, the brand is listed as VERIS, and the unit is used. Cosmetically, it shows minor scuffs and scratches, and it comes in non-original packaging. It was removed from decommissioned equipment and has not been tested, and no manuals, cords, or cables are included. If you want a 102553-OA without paying the high end of this comparison, this unit is the starting point. Just factor in the used condition and the untested note.
MGE UPS Systems Critical Power Monitoring System 102553-OA AK

Here is the same 102553-OA model number with MGE UPS Systems branding and the highest listed price in this comparison. Upstate Breaker Wholesale provides a one-year warranty on this unit, which makes it the one to compare if you want a formal warranty promise rather than the lowest price. The unit is used and the price tag is far larger than the other 102553-OA option in this group. If the budget has room and the MGE-branded 102553-OA part number matters, this is the one to look at.
MGE UPS SYSTEMS Z102198-0F Critical Power Monitoring System

This unit gives you the Z102198-0F part number in a system format rather than a display-only part. It is listed at a price just above the group's lowest, and it is used in excellent working condition, with origin United States. One thing to keep in mind: if several items are available, the unit you receive may not be the exact one pictured, but it will have the same part numbers and similar condition. That makes it a reasonable choice if you need the Z102198-0F system and can accept minor cosmetic variation.
MGE UPS Systems 102198-0F Critical Power Monitoring System Interface Display

This is the unit titled as an interface display, matched to the 102198-0F part number. It is priced in line with the lowest listed price in this group, and the condition is used. The part shows scuffs and scratches from regular industrial use, and it was removed from decommissioned equipment and not tested. No manual, cords, or cables are included. If all you need is the display/interface portion, this unit lets you buy only that piece rather than paying for the full Z102198-0F system. The untested condition is the main caveat.
Final recommendation by use case
- If you want a 102553-OA system at the lowest listed price, start with the MGE / VERIS 102553-OA KMGM UPS Systems Critical Power Monitoring System.
- If the MGE-branded 102553-OA part and a one-year warranty from the merchant are more important than price, choose the MGE UPS Systems Critical Power Monitoring System 102553-OA AK.
- If you need a Z102198-0F system unit close to the low price end, go with the MGE UPS SYSTEMS Z102198-0F Critical Power Monitoring System.
- If your system only needs the interface display, the MGE UPS Systems 102198-0F Critical Power Monitoring System Interface Display is the match.
