Printed circuit board LON node 8 A (SPS)

24 VDC LON node for smoke pressure systems (SPS).
Stabilised output voltage with ripple component < 1%
for a rated current of up to 8 A for supplying 2 drive
or control groups or for use as a power supply unit for
providing a constant supply of power.
Connection options for 10 automatic detectors type MSD
523 or UTD 523 and one wind/rain sensor.
230 VAC power supply and emergency power supplied by
maintenance-free 12 V emergency batteries for
operational readiness when the system is switched to
emergency power.
Optical signalling and maintenance-friendly fault
monitoring with error flashing code and forwarding to
the LON network.
Design and function in accordance with the series of
standards for smoke and heat extraction control systems
prEN 12101-9 and EN 12101-10 for functional safety and
power supply.
