Telefire ADR-4004TSW Switching power supply

Product Description

The Telefire ADR-4004TSW is a reliable switching power supply module specifically designed to power ADR-3000 analog addressable fire alarm control panels and TPS-34A auxiliary power supplies. This unit is responsible for providing stable 24 Vdc power to the system, as well as charging and monitoring the backup batteries. Its modular design allows for easy replacement and maintenance, fitting directly within the control panel enclosure or the auxiliary power supply cabinet.

The device accepts a 230 Vac mains input, converting it with high efficiency into the DC voltage required by the system. The built-in battery charger circuit intelligently manages connected batteries (up to 12 Ah capacity within the panel enclosure), ensuring long service life and uninterrupted operation during power failures.
