When output voltage drop is detected, an alarm (
a01
) and lowest
output voltage value are indicated alternately. The preset value of
detection voltage can be changed in the setting mode.
(From 18.5 to 27.5 V in 0.1-V steps. The value is fixed at 20.0 V for
the S8VS-06024A
/
S8VS-06024B.)
Further, an output (undervoltage output terminal (DC LOW)) to an
external device is given from the transistor to notify of the error
(excluding S8VS-06024A/S8VS-06024B/S8VS-

(Output voltage drop = OFF, i.e., no continuity at the undervoltage
output terminal (DC LOW).)

In the case that the
output voltage drops
below the set value (19.0 V)
and an alarm is issued
Note: 1. Operation begins after about three seconds since the AC
power is supplied.
2. The alarm is not indicated in the setting mode.
3. Press the
(Mode Key (8)) after the output voltage is
restored, to reset alarm indication.
4. The undervoltage alarm function may also operate when an
interruption in AC input is not restored within 20 ms.
5. The undervoltage alarm function monitors the output
terminal voltage of the Power Supply. To check the voltage
accurately, measure the voltage at the load end.
Note: Operation begins after about three seconds since the AC
power is supplied.
