Description
faulty, an interruption (less than
20 ms) occurs when the UPS
transfers from normal mode to
bypass mode. If Output freq.
track rate (Hz/s) is fast, the
inverter frequency is unstable.
Description
When the difference between the
bypass voltage and the rated
voltage exceeds the upper
threshold for the bypass voltage,
the system determines that the
bypass voltage is not normal and
that the bypass is unavailable.
When the difference between the
