  • Page 34: Operation Modes

    7. Operation Modes Uninterruptible Power Supplies (UPS) have an important function in the protection of the critical and sensi- tive loads from the irregular mains electricity conditions and they are used to supply uninterruptible energy to these loads. In such irregular mains electricity conditions, the user can provide an artificial energy supply to the equipment present in the office or at home by using an UPS.

  • Page 35: Online Mode (Norl)

    KEOR S 3-10 kVA 7.1. Online Mode (norl) Energy is drawn from the mains input. Loads are supplied through the rectifier and the inverter. The AC volt- age at the input is converted to a DC voltage by the rectifier. The inverter converts this DC voltage to an AC voltage with a stable sinusoidal waveform, amplitude and frequency.

  • Page 36: Bypass Mode

    Eco Operation mode does not provide perfect stability in frequency/waveform/rms value of the output voltage like in Online Operation. Thus, the use of this mode should be carefully executed according to the level of protection required by the application. Eco Operation mode does not provide electronic short circuit protection like in Online Operation.

  • Page 37: Battery Mode

    KEOR S 3-10 kVA Keor S 3kVA The mains voltage is required to be in certain range for Bypass Operation. Bypass range is 176VAC~ 264VAC or 187VAC~264VAC (It can be adjustable). In case the mains is out of the limit it cannot switch to Bypass Operation even if a fault occurs.

  • Page 38: Maintenance Bypass Mode (For 6-10Kva)

    The adjustment of frequency converter settings should be done by authorized Technical Personnel. 7.6.
