DA458-4: 1A 24VDC Rack-mount power supply with VRLA battery support and monitoring

This range of 19″ 3U rack mountable switch mode power supplies can accept 110V or 230VAC and will provide an output of 24VDC at up to 4A.

These units will house and charge up to 2 x 12Ah VRLA batteries and are equipped with two separate DPCO (Double Pole Change Over) contacts for mains fail and low voltage signalling.

Battery low voltage disconnect
If the voltage from the battery falls below 9.5VDC, for example after an extended mains failure, the battery terminal will disconnect. When the unit voltage recovers (i.e. when mains is restored) the battery terminals will reconnect, allowing recharge.

Fire-enable output switching can be driven from a 12V or 24VDC supply. A typical use for this relay would be interfacing a fire panel with the power supply to de-power magnetic locks in the event of a fire condition.
