■ Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by short-circuit
and overcurrent.
When the output current rises above 105% min. of the rated current,
the protection function is triggered, automatically decreasing the out-
put voltage. When the output current falls within the rated range, the
overload protection function is automatically cleared.

■ Overvoltage Protection
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the Power Supply fails. When an excessive
voltage that is approximately 140% of the rated voltage or more is
output, the output voltage is shut OFF, preventing damage to the load
due to overvoltage. Reset the input power by turning it OFF for at
least three minutes and then turning it back ON again.

The values shown in the above diagrams are for reference only.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or other overcurrent state continues dur-
ing operation.
Do not continue an overload state for longer than 30 sec-
onds. Eliminate the overcurrent state as soon as possible.
2. Internal parts may possibly be deteriorated or damaged if the
Power Supply is used for applications with frequent inrush cur-
rent or overloading at the load end. Do not use the Power Supply
for such applications.
Note: 1. Do not turn ON the input power again until the cause of the
overvoltage has been removed.
2. The overvoltage protection function may be activated when
the output voltage adjuster (V.ADJ) is set to a value that
exceeds +20% of the rated output voltage.
3. When the +S and −S terminals are opened with the short-
bar removed, the overvoltage protection function is
activated and the output voltage will be cut off.
■ Undervoltage Alarm Function (Indication and Output)
(Only S8VM-@@@24A@/P@)
If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an
output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@).
Transistor Output: Sinking type:
(NPN) (S8VM-@@@24A@)
Sourcing type: (PNP) (S8VM-@@@24P@)
30 VDC max., 50 mA max., Residual voltage when ON: 2 V or less, Leakage current when OFF: 0.1 mA or less

• Undervoltage Alarm Function 1 (DC LOW1)
Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V
lower than the voltage output at an output voltage of 24.0 V).
During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is
used as a latch holding function.)
• Undervoltage Alarm Function 2 (DC LOW2)
Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V).
During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights.
Note: 1. This function monitors the voltage at the Power Supply output terminals.
To check actual voltage, measure voltage on the load side.
2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1).
3. Once a voltage drop in the output voltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status
of the LED (6: Yellow) light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON
again.
4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output
hold status for detection may be reset.
