EATURES
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 plus additional current for
charging 2 x 12V standby batteries. Maximum battery life is assured using deep discharge protection to prevent
premature battery failure when operating in standby mode for extended periods. Two sets of volt-free contacts are
provided to signal (i) loss of mains and (ii) battery and loss of output faults. 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.
