T-peak
I-peak
T-peak presents while the unit is working within 110%~150% raterd output power.
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.
CURVE BCURVE A
T-peak presents while the unit is working within 110%~150% rated output power.
See Curve “B” for the variation of T-peak between output current and hold-up time.
If T-peak is more than the time setting in Curve “B”, the output voltage sill be shut
down for 3~4 seconds and then auto-recover.
