Thread: Back up Power solution

  1. #1

    Default Back up Power solution

    I am looking to install back up generator wired to my DB. Will run lights and plugs only however I am concerned about Voltage fluctuation when it comes to my computers and TV.
    I realise online UPS's are very expensive, anyone have other options in this regard. Would offline UPS work or perhaps a voltage regulator.

    I am not concerned about battery life on UPS.

    You'd be fairly safe with the PC and TV if they use switch mode power supplies.

    You do get line-interactive/offline power supplies that can perform active voltage regulation - like the APC SMart-UPS 1000VA (SUA1000i), but it's still fairly expensive: ~R3000 @ Rebeltech.

    I use the Intellipower 4, i have my Pc three drives 32 inch monitor woofer and speakers, headphones and modem - so when power goes i can still surf net, email, work in photoshop etc, it smoothly crosses over to the back up supply and lasts for about 7 hours, about two years ago i bought it for R1700 delivered

    @Ripykin:
    I hope you do realize that the Intellipower 4 takes 150Hz or 60Hz input, where as our Eskom electricity is at 50Hz.
    Secondly, it's transfer time is rather slow at 15-20ms to 40ms, compared to the 2-4ms of the APC Smart-UPS units.

    I certainly won't use something like that (Intellipower 4) to power my PC or any other sensitive/expensive electrical equipment!
