Simulated or stepped sine wave power, provided by entry-level UPS systems, may be problematic or incompatible with Active PFC devices. If you run equipment that is purely AC or is sensitive to AC fluctuations, then you probably need a pure sine wave UPS.

Patented GreenPower UPS advanced bypass circuitry reduces UPS energy consumption by up to 75% compared to competitive models. Participant must not disclose any CyberPower information labeled as confidential while participating in the Program and for five (5) years thereafter.

Product name and photography are for identification purposes only and may differ from the actual product. Others have unofficial comments from PSU manufacturer tech support saying that in 120V areas, there shouldn't be a problem with non-sine UPS.

All outlets feature surge protection to divert excess voltage away from sensitive electronic equipment during a utility power surge or power spike to prevent damage. Color icons clearly communicate UPS status: green for normal, yellow for warning, and red for alerts that may require action. Sine wave output is necessary for devices that require Active Power Factor Correction (Active PFC) power source compatibility.Automatic Voltage Regulation (AVR) in line interactive UPS systems stabilizes the incoming AC signal to maintain output power at a nominal 120 volts by controlling high and low voltages without resorting to battery power. CyberPower GreenPower UPS™ technology represents multiple advanced energy-saving designs that improve the operating efficiency and eliminate waste energy consumption. Advanced efficiency design (reduced fan operation), high-end system components, and GreenPower UPS technology help minimize sound emissions. The better your problem and question is described, the easier it is for other CyberPower owners to provide you with a good answer.

The "dirtier" looking one might be switching more aggressively (faster rise/fall times on the switching elements) or might have a less aggressive snubber - both of which might result in better efficiency. Anyway, kudos to CyberPower for going above and beyond, instead of simply giving me the “sorry, the unit is out of warranty, nothing we can do” line. Without sine wave power output, microprocessor-based equipment can become inoperative or sustain damage from power signal distortions.

CyberPower was recognized by CRN, a top news source for solution provider and the IT channel, to be one of the significant vendors of data center service provider supporting backup tools, virtual solutions, and cloud hosting from the aspects of efficient and environmental friendly manners.

Other added LCD control functions allow you to set up sensitivity levels, mute the alarm, monitor power vitals, and more. The CP1500PFCLCD has six battery backup and surge protected outlets and six surge protected outlets. Some point out that inrush current on active PFC PSUs could be another issue aside from the waveform. However, it was uncertain whether the issue was the charging system itself or a dead battery unable to be charged. Featured data line protection guards phones, networks, and communication equipment against surges/spikes and other power irregularities.You should plug your computer and monitor into these outlets and any externally powered critical data storage device.
