The power supply unit DCU 2401 R2 is the successor
model of the previous version DCU 2401 in the same
design and thus interchangeable. The DCU 2401 R2 is
used for the uninterruptible power supply (UPS) of
alarm devices, signal generators and linear fire
detectors according to EN 54-4. The device includes an
input power supply, UPS and battery charging function
and complies with the safety standard DIN EN 62368-
1. One of the advantages of this device is that the relay
card - which reports the status by means of integrated
potential-free contacts - is already integrated.
The energy storage unit is not included in the scope of delivery and must be purchased separately.
