UPS & CCTV Power Supplies UK
12 products in our Accessories range — trade-grade UK stock from CCTV Master.
This range covers power supplies for CCTV systems, plus general backup power: single-camera plug adapters, multi-way distribution boxes, an access control PSU, and one uninterruptible power supply (UPS) for backup during mains failure.
Most cameras run on 12V DC, fed either by a small plug-top adapter or a multi-camera distribution box that shares one mains lead across several cameras via a fused output.
How to choose
- Number of cameras: a single 12V 1.5A or 3A adapter suits one camera; systems with several cameras need a distribution box (4A–10A) or the 18-channel 15A fused unit.
- Connector type: check your camera takes a 5.5mm DC barrel plug, as used throughout this range.
- Current (amps): match or exceed your camera/recorder's rated draw — 1.5A and 3A units suit single low-draw cameras; 4A–10A boxes suit multi-camera runs.
- Access control: the PSU-12V-8A is sized for door entry and access control hardware rather than cameras.
- Backup power: the CertaUPS 800VA unit keeps a recorder or small system running through short power cuts, guarding against lost recordings.
Always confirm your existing cabling and connector match before buying a replacement or additional PSU.
Power — frequently asked questions
What amperage PSU do I need for one CCTV camera?
A 12V 1.5A or 3A adapter is normally enough for a single camera; check the camera's own rated current draw to be sure.
Can one power supply run multiple cameras?
Yes — the distribution boxes in this range (4A up to 10A, and an 18-channel 15A fused unit) supply several cameras from one mains connection.
What connector do these power supplies use?
The adapters and distribution boxes in this range use a 5.5mm DC barrel plug, which is standard on most CCTV cameras.
What does the UPS unit do?
The CertaUPS 800VA UPS provides battery backup and surge protection, keeping connected equipment such as a recorder running through a short mains power cut.
