QUINT-PS/ 1AC/24DC/40
Floating contact
Output 24 V DC
The floating signal contact opens and indicates that the set
output voltage has been undershot by more than 10 %.
Signals and ohmic loads up to a maximum of 30 V AC/DC and

currents to a maximum of 1 A (or maximum of 60 V DC with a
maximum of 0.5 A) can be switched. For heavily inductive
loads such as a relay, a suitable protection circuit (e.g.,
damping diode) is necessary.
DC OK
Active signal outputs
Output 24 V D C
The 18 ... 24 V DC signal is applied between the "DC OK" and
the "-" connecting terminal blocks or between "I < I N " and "-"
and can carry a maximum of 20 mA. By switching from "active

high" to "low", the DC OK signal output signalizes when the
set output voltage is fallen short of by more than 10 %.
The DC OK signal is decoupled from the power output. It is

thus not possible for devices connected in parallel to act as an
external power supply.
The POWER BOOST signal output I < I N signalizes that the
nominal current is exceeded. The power supply is then in
POWER BOOST mode. Thanks to this preventive function
monitoring, critical operating states can be responded to at an
early stage, prior to a voltage dip occurring.
The 18 ... 24 V DC signal can be directly connected to a logic
input for evaluation.

of malfunctioning, a common alarm is output. Any number of
devices can be looped in. This signal combination saves
