CONTROL (PROTECTION) PART

Note 4 : Short circuit protection works only for the N-side. Please select the external shunt resistance such that the SC trip-level is up to 1.7

times of the current rating.

5: Fault signal is asserted only corresponding to a SC or a UV failure at N-side, and the Fo pulse width is different for each failure modes.

For SC failure, Fo output is with a fixed width of 40

µs(min), but for UV failure, Fo outputs continuously during the whole UV period,

however, the minimum Fo pulse width is 40

µs(min) for very short UV period less than 40µs.
