We require a UPS with an supply voltage of 230v AC, we need to use 2 x 12v 1.3Ah SLA batteries in series (24v DC) which need a trickle charge and auto cut off when fully charged, these will be connected to the UPS via battery leads. We require a DPDT non latching relay to be energized when the mains power is active, the two normally closed (relay unenergized) relay terminals will be connected to the UPS battery output, the normally open terminals will each have a 2.5mm2 screw terminal. Both common contacts of the relay to have a separate 2.5mm2 screw terminal.

Can you please clarify if you need a complete UPS or a battery charger with a 24V output? Because UPS usually signifies an AC output in case of a power failure.
