Product Description
What the PSU-12V-1A-UK-BOX actually does
It takes a 220Vac mains input and outputs a steady 12Vdc at 1A — enough to run a single CCTV camera or a small low-draw device that needs a regulated 12V feed.
Why it's boxed like this
The unit ships in a metal hinged box that's key lockable, so it can be mounted in a plant room, loft or external cupboard without the electronics being exposed. A tamper switch and LED indicators mean you get a visible or alarmed warning if the box is opened without authorisation — useful where the PSU sits somewhere less supervised than the cameras themselves.
Battery backup built in
It includes a battery charging circuit with deep discharge protection, so if you fit a backup battery inside the box, the PSU will charge it and cut off before it's drained too far to recover — the kind of setup that keeps a camera running through a short mains outage.
Size
At 305 x 304 x 85mm, it's a wall-mounted box rather than a small plug-top adapter, so leave room for it near your recorder or camera run.
Before buying, check your camera's actual current draw against the 1A rating — if you're powering more than one device or a camera with IR illuminators drawing heavily at night, a single 1A output may not have enough headroom.

Frequently Asked Questions
How many cameras can the PSU-12V-1A-UK-BOX power?
It supplies 12Vdc at 1A total, so the number of cameras depends on their individual current draw — check each camera's rated consumption before combining loads.
Does the PSU-12V-1A-UK-BOX include a backup battery?
No battery is listed as included, but it has a battery charging circuit with deep discharge protection so you can fit your own backup battery inside the box.
What does the tamper switch on the PSU-12V-1A-UK-BOX do?
It's designed to flag if the metal box is opened, working alongside the LED indicators and key lockable design to protect the unit when it's sited somewhere unsupervised.
What size is the PSU-12V-1A-UK-BOX and where should it be mounted?
It measures 305 x 304 x 85mm, so it needs wall space near your recorder or camera run rather than being a compact plug-in adapter.
