    Bypass Function, Utility Mode to / from battery mode The UPS uses the input AC line as its stand-by source. in case of an O/L condition, the UPS will automaticallly transfer to the bypass line, if healthy input conditions exist, within 4 msec (2.5ms type.) to ensure that the critical load(s) continue to operate
    Auto Restart Yes
    Cold/Black Start Yes
    Over Load, Transfer to Bypass

    > 110% of FL: 30 seconds delay,

    150% of FL: 200 msec. delay

    Protections Input or Output UV/OV conditions. Inverter shutdown protection, Short Circuit on output. The UPS shuts down and won't transfer to bypass mode, will work normally once short circuit codition is removed
