DA422: 230V Input steel-cased 3A 12V DC power supply with 12Ah battery support

This simple range of multi-purpose metal-cased power supplies provides 3A of 13.7V DC via a fused output, for 12V DC equipment. The enclosure can also house a 12Ah VRLA battery, which the power supply will automatically charge while mains power is present, and use in the event of a mains power loss.

Manufactured and tested in Britain, this range of power supplies has a five-year warranty, allowing installers to fit and forget. It is ideal for where high reliability is required and where companies may have long service or maintenance contracts. Typical uses include powering door access controllers, electronic door releases, magnetic locks and CCTV cameras.
