CyberPower UPS

Owners of CyberPower’s CP1350PFCLCD and CP1500PFCLCD uninterruptible power supply (UPS) units, beware, as these UPSs can pose a potential fire hazard, according to user feedback on Reddit.

Based on preliminary data and online reports from users, the CP1350PFCLCD and CP1500PFCLCD, which are the rev 1 and rev 2 variants respectively, apparently contain a yellow adhesive as the primary adhesive that can eventually become conductive and corrosive due to aging and may cause a short circuit. circuit and may even cause a fire.

The issue with CyberPower’s UPS units was first noted in January 2022 on Canada’s RedFlagDeals forum by user “bluesun” who cited a YouTube video posted in May 2021 by computer engineer and YouTuber Mark Furneaux. However, the issue has resurfaced online after Reddit user “into_devoid” posted a video of their CP1500PFCLCD catching fire when it was turned on.

Shortly after the CyberPower UPS issue resurfaced, more users came forward to report their similar issues. For example, a Redditor uploaded a video of smoke coming out of his CP1000PFCLCD immediately after he replaced the battery as per CyberPower’s recommendation.

While it is common for manufacturers to use yellow glue, typically in the electronics industry, to bond bulky components, it can become partially conductive if it begins to change from yellow to brown or black over time. The duration of the adhesive also fluctuates and depends on the ambient temperature.

When Tom’s Hardware contacted CyberPower, a company representative told them that they cannot identify the issue on the Reddit video due to the lack of information. The company has recommended that the affected user or users send in their devices so that they can determine the cause of the problem.
