EN: Installation Sheet
Features
High efficiency cost effective power supply ideal for use in
Fire, Access Control and General Security applications.
Featuring a regulated 27.6 VDC output supplying continuous
full rated current to load plus additional current for charging
two 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. Front panel
mounted LEDs show presence of mains and 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.
