The software supports local notifications of faults, but it can also be set to send an email on major events. This option can be an effective energy-saving measure for workspaces and areas where the connected equipment is supposed to operate only within a certain range of hours every week. Weekly timing schedules can also be programmed into the UPS, allowing the powering of equipment only for a certain time period every day. Users may also enter their region and the kWh price for the UPS to calculate the monetary cost and estimated CO2 emissions of the energy used. It also calculates and displays the energy consumption of the UPS and its connected devices across a user-defined time period. It records the number and the length of all electrical faults and also monitors the AVR. The software performs quite well for event recording - as long as the system is powered on. Those that would like to keep track of events across multiple systems and/or after system upgrades, CyberPower offers paid cloud-based solutions. For example, if installed on a new computer, the number of events will be zero regardless of how much time the UPS has previously been in use. Note that the Personal version of the software is PC-based and will only record events locally. It is a simple but functional software package that can adjust the basic functions of the UPS and logs its events. The SoftwareĬyberPower supplies the PowerPanel Personal software package for free. The parasitic power draw of the UPS when the batteries are charged is extremely small, at less than 1.5 Watts when the LCD is also turned off. Once turned off, there is no voltage on any of the outputs of the UPS. It does not really affect the RMS output of the unit over time but the instability of the timing circuitry on a brand-new unit is peculiar. Every 1.5 second or so, the output voltage is slightly boosted, reaching up to nearly 1200V peak-to-peak for less than 100ms. One undesirable effect we noticed regarding the output of the CyberPower ValuePro VP1600ELCD 1600 VA is that the output is not perfectly stable over time. The RMS voltage value of the output always remains stable at 230V.īattery Output Waveform - 20% load, 3 second period The output waveform shifts greatly as the load increases but it basically always remains a two-step square wave. The peak-to-peak voltage of this waveform is over 1000 V due to these peaks but they are too short to cause any kind of damage.īattery Output Waveform - 50% load (left) / 100% load (right)Īs is the case with such designs, the circuitry of the CyberPower ValuePro VP1600ELCD 1600 VA adjusts the timing of the MOSFETS to maintain a stable output. There is a momentary peak at the front of the second step, which is extremely high but also very short. It does not even resemble a sinewave – it is but a two-step square wave that ultimately produces a 230 V RMS output. 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.
