Product Description
The DCU 2401 R2 is the successor model to the DCU 2401, with an identical design, and is therefore directly interchangeable. It ensures an uninterruptible power supply for alarm devices, signalling devices and linear fire detectors in accordance with EN 54-4 and complies with the safety standard DIN EN 62368-1. The input power supply, UPS and battery charging functions are integrated – as is a relay board that reports the status via potential-free contacts.
