24V-5A Power Supply Unit

The PSU240517 is a 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.

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.
