All of this range are unregulated DC supplies which calculate to be 12V (13.6) or 24 (26V) at the maximum load.

If the maximum load is not drawn, the voltage is higher.

The unit has an independent battery charging circuit, which is switched on line when mains fail.

There is also a mains fail clean relay indication for remote signalling.

These units are fan cooled, output fused and battery fused.

This is a battery charger unit not a power supply, it is designed to charge batteries for a 48 volt system.

This unit has a trickle top up charge and a fast charge monitoring system, which monitors the battery terminal voltage to calculate the battery state of charge keeping the battery terminal voltage at full charge to 54.5volts.

There is a kick start to activate the charge rate if the batteries are be above the fast turn off rate and running on trickle charge but below 54.5 volts.
