DA457: 12V DC Rack-mount power supply with VRLA battery support and monitoring
This range of 19" 3U rack-mountable switched-mode power supplies can accept 110V or 230V and will provide a regulated output of 12V DC at up to 8A.
- Integrated UPS function VRLA Battery back-up
- Fire enable
- Mains failure & Low-battery signalling
- Low-battery disconnect
- House and charge 2 x 12Ah VRLA batteries
- 19" 3U rack-mountable enclosure
- Removable front plate
- Input either 110V or 230V
- Output via front-mounted termination
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 & low-voltage signalling.
Battery low-voltage disconnect, if the voltage from the battery falls below 9.5V 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 can be driven from a 12V or 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.
VRLA Batteries are not included.
