Power Supply Unit with Battery Backup
A mains powered, user selectable output (1225), battery supported Standby Power Supply, housed in a robust, compact wall mounted steel fabricated case (except 4605) with a lift-off hinged front panel. Case is epoxy powder coated, with cable entry provided by 20mm conduit knock-outs located in top and bottom & each side of the case. A battery charging output is provided to continuously charge up to either 1 x 12v 7 A.H or 2 x 12v 3 A.H (connected in series) Sealed Lead Acid Batteries. This output is fused and current limited against the high demand made by a battery if it has been allowed to go beyond its fully discharged point. In the event of a mains power failure, standby power is automatically provided from a battery or batteries connected to the battery charging output (batteries sold separately).

NOTE: It is recommended that the power supply unit be sited as close as possible to its load, and a minimum conductor C.S.A. of 0.75mm sq. (24/0.2) with a maximum run length of 12 metres at full load, be used.
