Product Description
One-line answer
The QVIS PSU-5A-5B is a 5-port 12V DC power distribution box with 5A total output, letting one mains feed run several CCTV cameras from a single cabinet or loft void.
Why installers spec it
On multi-camera jobs, running a plug-top adaptor to every camera is messy and eats sockets. This unit takes one 240V AC mains connection and breaks it out to 5 individual 12V DC ports, so cabling consolidates back to one point — a comms cupboard, loft, or riser — rather than trailing adaptors around a building.
Sizing the load
The 5A rating is a shared total across all five ports, not 5A per port. Before specifying it, total the rated current draw of every camera you intend to connect and confirm it sits within the 5A budget, with headroom for IR LEDs pulling more current at night.
Protection and build
- PTC (Positive Temperature Coefficient) protection replaces a traditional fuse, resetting automatically once a fault clears — no fuse changes on a call-back
- Includes built-in protection against over-voltage, over-current and short circuits.
- Operating range 0°C to +40°C, so this is an indoor or sheltered enclosure install, not exposed external mounting
- CE, FCC and RoHS compliant
Where it fits
Suits retail units, small offices, and residential blocks running a handful of cameras from one recorder location — anywhere centralising power beats running separate adaptors to each camera position.

Frequently Asked Questions
Is the 5A rating per port or shared across all five ports?
It's a shared total of 5A across all five ports, so add up the current draw of every camera you plan to connect before specifying this unit.
Can this unit be fitted outdoors?
No — its operating range is 0°C to +40°C, which points to an indoor or sheltered enclosure installation rather than direct external exposure.
Does it need a fuse replaced if a fault occurs?
No — it uses PTC (Positive Temperature Coefficient) protection instead of a traditional fuse, which resets automatically once the fault clears.
What mains input does it take?
It runs from a standard 240V AC input, so it connects directly to a UK mains socket without an adaptor.
