The Dycon D2401-A is a 24Vdc switched-mode 1A power supply ideally suited for powering magnetic fire alarm door retainers, access control applications and general 24VDC power applications which do not need battery backup. This unit is designed for highly inductive loads such as magnetic door retainers and releases, eliminating the need for additional control relays and reducing the chance of an ‘electrical spike’ causing problems, which is a frequent cause of personnel delays and expensive engineer call outs. These units, additionally, have a normally closed (NC) volt-free opto-relay outputforremotely signalling the status and serviceability of units. This output can be used to indicate problems either locally or remotely to a Fire Alarm panel or to a suitable signalling device. All units are protected by Dycon’s intelligent electronic fuse technology with automatic reset to reduce system downtime. They all feature Dycon’s unique protective technology, includes intelligent and capacitive load switching, surge protection and snubbing.

The Dycon A metal housing dimensions are 235mm H x 170mm W x 85mm D.
