T-peak represents the period during which the output current is at 110% to

150% of nominal (shown as I-peak). Curve B shows the relationship between

the percentage of peak current (I-peak) and the allowable duration (T-peak).

If the peak current takes longer than the allowed duration indicated by curve

B, the output current will drop to a constant limited current of 105% of

nominal. The unit between peak currents (T-normal) is dependant upon the

output current drawn between the peaks (I-normal) and curve A shows the

relationship between the two. The higher the percentage of normal current

(I-normal) is of the nominal current, the longer the interval (T-normal) before

the next peak current can be drawn.
