High efficiency cost effective power supply ideal for use in Fire, Access Control and General Security
applications. Featuring a regulated 27.6Vdc output supplying continuous full rated current to load and up to
an additional 0.5A for charging 2 x 12V standby batteries, if fitted. The universal mains input voltage enables
the power supply to be used across a wide geographical area. The highly efficient switch mode design ensures
low operating costs, generates less heat and with a small physical size increases the room available for
additional PCBs or cables. The modular construction simplifies maintenance.
