This switch mode BF560-24 PSU features a mains’ fail simulation mode, temperature sensor, and LED status display which serves to indicate supply present, general fault, and auxiliary fault conditions.

The BF560-24 PSU is available with or without optional batteries for cases where ensuring you have a backup power source is a concern. It takes two 12V, 3.2Ah SLA batteries and offers two selectable battery charge currents. Deep discharge protection and EN54 compliant reporting of impedance faults also work to prolong battery life.

What’s more, this C-TEC PSU has a plastic cover to prevent possible electrocution and includes a single-pole volt-free changeover relay that switches for any fault condition.

The 24V 1.5A PSU is IP30 rated for interior use, has LPCB approval, and meets EN50131-6 grades 1-4 for security applications too. Plus, it can be customised to your exact specifications.
