Battery Backed Up PSU
This project uses a solar panel
controller to provide battery backup to a modified 10 Amp 18 fused output PSU.
A 20 Amp hour lead acid battery provide
backup power when mains power fails.
The charge controller keeps the battery
charged correctly and also prevents over discharge of the battery.
Automatic Battery backed up PSU. Mouse over to see battery
In normal mode the charge current is displayed on the left of
the display and the LED on the PSU box turns Green.
In battery backup mode the charging current display in Amps
and the LED on the PSU box turns Red.
Power Supply Panel
CCTV Camera Power Supply Distribution Box Unit 12V 10A 18 Channels
Improve camera security and reliability
- Most CCTV cameras are mains power operated, often by plugging them
into a nearby socket. The Nordstrand CCTV Power Supply Box reduces
the risk of deliberate or accidental tampering by securing power
supplies for multiple cameras in one lockable box.
Easy to install and maintain
- The Nordstrand camera power box can be wall mounted anywhere,
keeping cables and power supplies secure and tidy. LED indicators
allow you to tell if the cameras are powered, making it easy to
troubleshoot problems. A single on/off power switch lets you reboot
or shut down the system if required and a built-in PTC fuse turns it
off when current reaches 1.1A.
Choose the right box for your system
- The Nordstrand CCTV Power Supply Boxes are designed to work with
most commercial and domestic CCTV systems available in the UK. We
have two variations that can handle up to 9 or 18 channels,
supplying up to 1.11A per channel. The box is powered by a standard
UK AC socket and a mains lead is included. The electrical input
required is mains power: AC 100-240V – 50/60Hz. The output is DC 12V
- 5A, 60W or DC12V - 10A 120W, suitable for most CCTV cameras.

Solar Charge Controller
The 12volt supply from the
PSU panel is fed into the solar panel input of the controller.
The battery terminal goes
to the lead acid battery and the 12volt battery backed up load to the power
supply PCB fuses 10-18.

All 240v wiring is removed
from the circuit board and is connected directly the the terminals on the power
The switch and terminal
block on the PCB are then redundant.
The main 12v power rail is
then cut between the 9th & 10 fuse.
Fuses 1 to 9 are connected
to the non battery backed up supply.
Fuses 10 to 18 are
connected to the battery backed up supply.
the cut in the 12volt rail can be seen on the back of the PCB.
The power supply unit is connected to a
current cost IAM and is fed to the Meteoplug data server to monitor power use.
Note the power goes up at night due to the
connected CCT cameras using IR LEDs during the hours of darkness.
