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.
Indicator
Green: DC ON
Red: DC LOW
Green: DC ON
(see note 1)
Red: DC LOW
Green: DC ON
Red: DC LOW
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.

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.
If the voltage at the output terminal is 0 V, both the
green and red indicators will not be lit.
