See Curve “B” for the variation in T-Peak between output current and hold-up time. If T-peak is more than the time setting in Curve “B”, the output current will drop to the constant limit (I-normal) that is 105% of the rated power. Meanwhile, I-normal and T-normal will be presenting. See Curve “A” for the timing back to I-Peak of T-normal and this mode can be used for easy 2-stage battery chargers.
