Power supplies that keep your access control doors working.
A power supply unit (PSU) gives your access control system the correct voltage, so locks and readers work reliably. Locks draw real current, so size the PSU for every device it feeds.
How do I choose a PSU?
- Match the voltage: check the voltage your controller, readers and locks need, and choose a PSU that gives it.
- Add up the current: total the current of every lock and reader on the PSU, and leave some headroom.
- Plan for power cuts: a PSU with a standby battery keeps the door behaving predictably when the mains goes off.
- Check the lock type: a fail-safe lock unlocks without power and a fail-secure lock stays locked. See door locks.
Not sure which PSU you need? Call us on 01902 902251. We deliver to England, Scotland and Wales within 1–2 working days.
