Here we can see the main difference between the CP1500 AVR LCD and the CP1500 PFC LCD. In order to test the waveform outputted by the UPS, we connected an oscilloscope to the UPS and took some screenshots of the waveform both with AC power connected simulating normal running conditions and without AC power connected simulating a power outage. These are expensive, but they are almost guaranteed safe for even the most sensitive power supplies. High end UPSes generally feature true sine wave inverters which generate power either exactly or almost exactly the way you’d get from the electrical grid. Some power supplies such as those with active power factor correction may have issues with the stepped sine wave. Some units may produce one more step in the middle, some may not. Stepped sine waves are generally safe for most modern systems with high quality power supplies, but it’s not ideal. Power here goes from one extreme to zero to another extreme back to zero. Most entry level to mid-range UPSes generate a stepped square wave which looks something like this. These tend to cause problems with electronics and may even damage sensitive electronics so you typically won’t see these on newer UPSes. Here are examples of a few of the different types of waveforms generated by different inverters.Ĭheaper UPSes contain square wave inverters which are very cheap, basic inverters that simply swings voltages from one extreme to the other.
Cheaper power inverters take the easy way out and simply swing between extremes of voltages while more expensive inverters are able to fully emulate a true sine wave provided by the electric company. Like all products, there are different levels of quality between power inverters. Since batteries in a UPS are DC and computer power supplies are designed to use AC power, UPSes require onboard inverters to convert DC to AC power. For a typical system load of 200W, the CP1500 AVR was able to achieve 25 minutes of runtime while the CP1500 PFC was able to achieve 24 minutes of runtime which should be more than enough to save your work and shut off the system.

Runtime on both the CyberPower CP1500 AVR and PFC units were quite a bit better than expected, especially when compared to the APC Back-UPS Pro 1500 reviewed previously. After charging up the UPS to maximum capacity, we plugged in the measured load until the power ran out, then recorded the time it took for power to run out. By chaining the bulbs together, we could load the UPS to a fairly precise amount of power draw.

In order to test the runtime of the UPS, we devised a test using a series of 50w fluorescent lightbulbs. CyberPower CP1500 AVR LCD, CP1500 PFC LCD UPS Performance Runtime This includes schedules, the configuration of notifications/alarms, how the UPS should react in the event of a power outage, at what voltages does the UPS intervene, self testing, and the sensitivity to input voltage. Under the configuration section, a number of configuration and testing options are available. Here’s a look at the packaging for the CyberPower CP1500 AVR LCD. A Closer Look at the CyberPower CP1500 AVR LCD We’ll be sure to take a closer look at that later in the review. While the CP1500 AVR LCD features the ability to output a simulated sine wave, the CP1500 PFC LCD features the ability to output a true sine wave, which is necessary for more sensitive electronic equipment as well as systems with special active PFC power supplies. The main difference between the CyberPower CP1500 AVR LCD and the CP1500 PFC LCD is in their electrical output wave form.
Looking at the specifications, both the CyberPower CP1500 AVR LCD and CP1500 PFC LCD feature a line-interactive topology and both are rated at 1500VA, which is the highest capacity in their respective lineups. Today we’ll be reviewing two UPSes from CyberPower, the CyberPower CP1500 AVR LCD and the CyberPower CP1500 PFC LCD, both of which are designed to protect PCs and other sensitive electronic equipment from common issues in the power grid. This is especially important if you’ve spent thousands of dollars for the best system possible since at the end of the day, it really only takes a single surge, brown out, or power outage from the utility company to wreak havoc on your precious semiconductors.

If you own a PC and you’d be quite bummed if it died because your utility company sucks, a UPS (Uninterruptible Power Supply) is practically a must.
