24V DC (26V) 4A rack mount power supply
with fire enable & VRLA battery backup support
Made in Britain
Description

DA458 19" 3U rack mountable switch mode power supplies that can provide a regulated output of 24V DC at up to 4A.

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

Battery low voltage disconnect; if the voltage from the batteries falls below 19V DC, for example after an extended mains failure, the battery terminal will disconnect. When the unit voltage recovers (when mains is resumed) the battery terminals will reconnect, allowing recharge.

Fire enable output switching is driven from a 24V DC 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.
