QUINT-PS/ 3AC/24DC/20
Floating contact
Output 24 V DC
The floating signal contact opens and indicates that the set
output voltage has undershot by more than 10%. Signals and
ohmic loads of up to maximum 30 V and currents of maximum
max.

For heavily inductive loads such as a relay, a suitable
protection circuit (e.g. damping diode) is necessary.
Active signal outputs
Output 24 V D C
The 18 ... 24 V DC signal is applied between the "DC OK" and
the "–" connection terminal blocks or between "I < I N " and "–"
and can carry up to 20 mA. By switching from "active high" to

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

ensures that an external supply does not enter from devices
connected in parallel.
The POWER BOOST signal output I < I N signalizes that the
nominal current is exceeded. The power supply unit is then in
the POWER BOOST mode. Using this preventive function
monitoring, critical operating statuses can be governed at an
early stage before it results in a voltage dip.
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
