Depending on the manufacturer and cost of the product, designers will make the corresponding effort to simulate a true sine wave as much as possible.Īs expected from a UPS at this price point and with such a high power output, the output quality while on battery backup is quite poor. The better the circuitry design, the more the steps, thus the better the approximation to a true sine wave output. This approximation typically is a ladder wave with a few steps. What that means is that the output will not be close to the standard sine wave that we receive from grid, but an approximation of it. The CyberPower ValuePro VP1600ELCD 1600 VA is a unit with a “modified sine wave” output. These figures are achieved with the batteries fully charged while they are still brand new. These times are great considering the UPS also lacks any active cooling.

In theory, the UPS can hold a lightly loaded typical PC for over than half an hour. The runtime is well over two hours with a load of 50 Watts, a little over 10 minutes with a load of 500 Watts, and slightly less than 2 minutes with the UPS fully loaded. Our load testing reveals that CyberPower’s running charts are quite accurate. There are minor frequency variations but these are exceptionally small.
The RMS voltage and frequency output look to be extremely close to the expected 230V/50Hz output. The transfer times are exceptional, with the unit requiring less than 4 ms to switch while fully loaded. The basic electrical figures of the CyberPower ValuePro VP1600ELCD 1600 VA UPS are quite good – unexpectedly so, in fact.
