Backup power supplies 24V / 3A

This energy-efficient power supply offers a cost-effective solution for fire alarm, access control and general security systems. In addition to supplying a regulated rated current of 27.6 V DC at full load, it can charge 2 x 12 V back-up batteries. Deep discharge protection optimizes their autonomy, preventing failure in the event of prolonged use. Two sets of dry-contact relays signal (i) mains supply interruptions, as well as (ii) battery or output failures. The universal mains input voltage enables the power supply to operate in many regions. Its switch-mode design offers excellent energy efficiency at low operating cost. It heats up less, and its compact size facilitates installation of additional circuits and cables. Finally, its modular design simplifies maintenance.
