Fact
Protecting equipment that uses an Active PFC power supply with a non-sine wave UPS can cause data loss, hard shutdowns or a catastrophic failure!
Why does this happen?
Over the last 10 years, power supply unit (PSU) manufacturers have transitioned to focusing on efficiency issues by increasing Power Factor in addition to reliability, quality and capacity. Problems can occur when using simulated sine wave UPS systems with more sensitive devices and electronic equipment. When on battery power, higher-end workstations and computer systems that incorporate Active Power Factor Correction (PFC) power supplies may unexpectedly shut down or crash entirely when used with a simulated sine wave UPS.
Critical Factor
Simulated sine wave output wave form produces a zero-output state during the phase change cycle resulting in a power "gap." This gap may cause power interruption for equipment with Active PFC power supplies when switching from AC power output to simulated sine wave output (battery mode).
The Solution
The PFC Sinewave Series from CyberPower ensures equipment utilizing Active PFC power supplies do not unexpectedly shutdown or experience harmful stress when switching from AC power to UPS battery power.
With pure sine wave output, the PFC Sinewave UPS systems provide continuous output during the phase change cycle and support equipment that utilizes Active PFC power supplies.
Pure sine wave is better 100% of the time
100% compatible with new Active PFC power supplies
A clean output waveform produced by electrical utility
Best power source from high-end electronics to small servers
Top computer manufacturers –HP, Lenovo, Dell and Acer– recommend Uninterruptible Power Supplies (UPS) based on pure sine wave output.
"Since its introduction, Active PFC technology has yielded significant improvements in computer power supply efficiency. The technology continues to improve over time but as efficiency improves, sensitivity to the waveform output of power sources increases. As a result, UPS solutions that worked with early Active PFC power supplies may be incompatible with later, more efficient, Active PFC power supplies."
