    Dycon DX24  24V Switched Mode Power Supplied with Optional Battery Charging

    Dycon D240X and D241X Series units are 24Vdc switched-mode 1-3A power supplies, ideally suited for use with fire alarm door retainers, access control applications and general power applications.

    The D240X units have a normally closed (NC) volt-free output for remotely signalling the status and service ability of units. This output can be used to indicate problems either locally using or remotely via a suitable signalling device. The D241X versions do not have this output but do have full standby battery charging capability. The switched output of all these units is designed for highly inductive loads (magnetic door retainers and releases) eliminating the need for additional control relays and circuitry and eliminating the chance of an ‘electrical spike’ causing a door to remain closed or open, a frequent cause of personnel delays and expensive engineer call outs.

    Using Dycon’s unique protective technology, the range features intelligent and capacitive load switching surge protection and snubbing. All units are protected by Dycon’s unique intelligent electronic fuse technology with automatic reset to reduce system downtime.
