It is designed and timed to draw power only at the very peak of a smooth sine wave. When you feed an Active PFC power supply a clunky, stepped waveform from a cheap UPS, it gets confused.
Utility power supplies electricity in the form of sine wave alternating current. When the UPS is in normal mode, it passes the same electrical sine wave to your connected devices.
When the wave has been cleaned up, it''s called a “pure” sine wave, since the wave has been smoothed out. However, cleaning up the wave isn''t always needed, and it costs more than
There are appliances that rely on the shape of a sine wave to operate (such as certain kind of speed/power controllers for motors or light dimmers), these won''t work on a square-ish wave.
When it comes to uninterruptible power supply (UPS) systems, the type of sine wave output plays a crucial role in determining efficiency, compatibility, and overall power quality. There
A pure sine wave uninterruptible power supply (UPS) delivers clean, stable electricity resembling utility power, critical for sensitive electronics like medical devices or servers.
Our pure sine wave UPS provides improved protection for your appliance, ensuring consistent, safe power. Learn more about our pure sine wave UPS here.
A pulse width modulated squarewave (also called simulated sine wave) is considerably easier to produce in a UPS. This type of waveform is quite suitable for virtually all electronic business
Waveform Output: A pure sine wave UPS inverter generates a waveform that closely resembles the sine wave produced by utility companies. It''s a smooth, continuous, and consistent
Because power runs through an online UPS continually, output is a perfect sine wave. This type of UPS protects the critical load from virtually all power disturbances, including subtle harmonics and
