Supreme Audio Power AC Regeneration With Battery Backup

The ProPower 490 battery back-up power re-generator quietly generates a new, clean, 120 volt 60 cycle sine wave right beside your audio or home theater system, so there is no opportunity for outside influences to introduce unwanted waveform distortions. It features 2 pass-through high current receptacles for larger power amps but the 490′s output of 750 watts on short duration and 1000 watts peak is more than enough for mid-sized stereo amps and high powered 7.1 channel home theater receivers in a normal sized room. The 490′s on-board battery system provides the reference voltage, and provides total isolation for your system from the utility power, regardless of whats occurring on the utility line, even in a black-out.



  • 1000 VA/490 watts continuous load, 750 watts short duration, 1000 watts peak
  • 10 amps RMS, 14 amps short duration, 18 amps peak
  • 6 Hubbell NEMA 5-15 outlets / 2 Hour Battery Back-up
  • Ideal for 2 channel and mid-power home theater, DAC’s, Headphone Amps
