Family of UPS (uninterruptible power supply) or English UPS (UNINTERRUPTED power supply) Prosine Series.

For a slightly higher cost you get a UPS with performance similar to a UPS On-Line in the waveform of the UPS output. They have a controller based on PWM or MAP (pulse width modulation) that allows a sine wave output. Compact in size come in different versions that vary according to capacity and the type of output jacks you have. Besides this series of UPS can be managed from a computer with USB port and using compatible software.
