Dycon 24VDC 2A Power Supply Unit for Fire Door Retainers (D2402-A)

The Dycon D2402-A is a high-performance power supply designed to provide a reliable and efficient power source for various applications. With its switched-mode technology and 24Vdc output, this power supply is particularly well-suited for powering magnetic fire alarm door retainers, access control systems, and other 24VDC power applications.

One notable feature of the Dycon D2402-A is its ability to handle highly inductive loads, such as magnetic door retainers and releases, without the need for additional control relays. This eliminates the risk of electrical spikes that can cause disruptions and delays, saving both time and money on engineer call outs. The power supply also incorporates a normally closed (NC) volt-free opto-relay output, allowing for remote signalling of the unit's status and serviceability. This output can be used to indicate problems locally or remotely, either to a Fire Alarm panel or to a suitable signalling device.

To ensure system reliability, all units are equipped with Dycon's intelligent electronic fuse technology, which offers automatic reset functionality to minimise system downtime. Additionally, the Dycon D2402-A features advanced protective measures, including intelligent and capacitive load switching, surge protection, and snubbing. These features safeguard the power supply and connected devices from potential damage caused by power surges or voltage fluctuations.
