Power Supply for Access Control

This 12V 5A unit powers electric locks, controllers, readers and exit buttons in a single enclosure. It accepts AC input from 100 to 260V, making it suitable for standard mains supplies worldwide. The supply is designed for installations that run one or two locks from the same source. It replaces separate transformers and reduces wiring complexity.

Metal Enclosure with Selectable Outputs

A metal case provides physical protection and helps suppress interference in busy electrical environments. The output terminals offer both normally closed and normally open contacts so the same unit can drive fail-safe or fail-secure locks. An adjustable delay circuit lets you set the lock release time anywhere from 0 to 15 seconds. Automatic short-circuit protection disconnects the output until the fault is cleared.

5 Amp Rating for Dual Lock Installations

The 5A continuous rating is the deciding figure: it allows two locks to operate simultaneously without voltage sag, whereas a 3A supply is only specified for a single lock. If your project uses one lock, a lower-rated unit will work; if it uses two, this 5A model is the stable choice. No other current rating is offered in this series.
