Operation
Undervoltage Alarm Indicator and Output Function
(All Models Except for S82K-24024/P24024)
If the output voltage at the output terminal drops to 75% to 90% of the rated voltage, the red indicator of the S82K (DC LOW indicator) will be lit. In
the case of the S82K-10024/24024T, a voltage drop alarm will be output via the relay available in the models (DC LOW output).
Note:
This function detects the voltage at the output terminal of the Power Supply. To check the precise output voltage, measure the voltage
at the terminal of the load.

If the voltage at the output terminal is more than 90%
of the rated voltage, the green indicator will be lit.

If the voltage at the output terminal is 75% to 90%,
the red indicator will be lit.
Green:
DC ON
Red:
DC LOW
If the voltage at the output terminal is 0 V, both the
green and red indicators will not be lit.
Note:
1. The more the voltage at the output terminal drops, the darker both the green and red indicators will be.
2. The relay contacts have a capacity of 0.1 A at 24 VDC.
