The ideal form for AC (Alternating Current) devices is a sine wave. Most of the UPSs on the market (including the computer UPS) generate the so called Modified Sinewave, which actually is comprised of rectangular impulses and the output voltage is totally different, compared to the mains voltage.
All inductive loads (electrical motors, pumps, transformers) and and most of the specialized electronics are designed to work only with sine wave voltage. The non-sinewave power makes these loads work inefficiently (higher power consumption, heating up) as the precise electronics might even not work at all (gas boilers, pellet boilers, etc.).
SineUPS can be used to power domestic and industrial devices:
- circulation pumps
- gas & pellet boiler controls
- audio, TV
