QUINT-PS/3AC/24DC/20
103132_en_00 PHOENIX CONTACT 11
Output
The connection is established using screw connections on
the screw connection of the DC output:
24 V DC: "+" and "–"; DC OK switching output active: "DC
OK" and "–"; DC OK output floating: "13" and "14"; POWER
BOOST switching output active: "I < I
N
" and "–".
At the time of delivery, the output voltage is 24 V DC. The
output voltage can be set on the potentiometer.
Protection of the secondary side
The device is electronically protected against short circuit
and idling. In the event of a malfunction, the output voltage is
limited to 35 V DC.
ATTENTION
Make sure that all output lines are
dimensioned according to the maximum
output current or are separately protected. The
cables on the secondary side must have
sufficiently large cross sections in order to
keep the voltage drops on the lines as low as
possible.
Signaling
The active signal output, the floating signal contact and the active POWER BOOST switching output are provided for
function monitoring. The DC OK-LED and the BOOST-LED also enable the function evaluation of the power supply unit
directly on the operation site (refer to the output characteristic curve).
