Normally works within 105 ~ 150% rated output power for more than 3 sec and then shutdown
O/P voltage with auto-recovery, >150% rated power or short circuit is constant current limiting,
if o/p drop to 40% rating output voltage then shutdown and auto-recover 5 time, if fault condition
not remove in this 5 time, the system well be shutdown and re-power on to recover.

1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
2.Derating may be needed under low input voltages. Please check the de-rating curve for more details.
3.Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47 uf parallel capacitor.
4.Tolerance: includes set up tolerance, line regulation and load regulation.
5.The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed
that it still meets EMC directives.

T-peak
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 is taken for longer that the allowed duration indicated by curve B,
the output current will drop to a constant limited current of 105% of nominal, then.
The unit between peak currents (T-NORMAL) is dependant up on 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.

* Place an additional capacitor to have a better
performance of auxiliary power operation.
* The grounding of "AUX" power should be
connected to "GND" port. If " V-" is connected
as Grounding, make sure to short the GND
and V- ports.
