12V 3A Adjustable Delay Power Supply

Dimensions: 120mm x 90mm x 35mm. Weight: Approx. 0.45kg (estimated from iron construction and size). Output: Stable DC 12V at up to 3A continuous current. Housing material: Durable iron casing with white finish. Includes wall-mounting hanging hole on rear panel for secure, space-saving installation. Features an integrated delay control circuit allowing precise adjustment of output activation time from 0 to 15 seconds — ideal for coordinating lock release timing in access systems. Offers selectable NC (Normally Closed) or NO (Normally Open) output modes, ensuring compatibility with a wide range of electric strikes, magnetic locks, and other door locking mechanisms used in UK/EU access control setups. Designed for reliability in real-world security environments: built-in anti-interference circuitry maintains consistent operation even near other electronic devices or in electrically noisy locations such as building entrances, server rooms or car park barriers.
