Description

Power for one small camera.
12V DC. 500mA. 2.1 mm plug.
The SR-PSU-12V500mA is a switch mode plug-pack with a 2.1 mm centre-positive plug on a lead of about 1.8 m. It suits a single Swann or other 12V CCTV camera, a CCTV microphone, or any 12V device that draws 0.5 A or less.
In one sentence: the SR-PSU-12V500mA is an Australian approved 12V DC, 500mA switch mode plug-pack, 100 to 240V AC input, with a 2.1 mm centre-positive plug on a lead of about 1.8 m, for one camera or small 12V device.
0.5 A in total. Check your camera's label first.
This supply gives up to 500 mA (0.5 A). Check the current on your camera's label or manual. Cameras with infrared draw more at night: if the label shows more than 0.5 A, choose our 12V 1A or 2A supply instead.
- 12V 500mA plug-pack power supply with 2.1 mm DC lead
- A power point within reach of the lead
- An extension lead or splitter if the camera is further away
A clean 12V for the small jobs.
One camera, a microphone, a sensor: plenty of 12V gear only needs half an amp. This switch mode supply delivers 12V DC at up to 500 mA on a 2.1 mm centre-positive plug, takes any mains input from 100 to 240V, and meets MEPS Level IV efficiency.

Plug-pack
Australian pins, 100 to 240V input.
It plugs straight into an Australian power point. Input is 100 to 240V AC, 50/60Hz, 0.35 A max. The switch mode design meets MEPS Level IV efficiency.

DC plug
2.1 mm centre positive, about 1.8 m lead.
The centre is +12V and the outer sleeve is negative, the usual CCTV layout. The 12V lead is about 1.8 m long.
How it goes in
Plugged in a minute.
01
Check the label
The camera must take 12V DC on a 2.1 mm centre-positive plug and draw 0.5 A (500 mA) or less.
02
Plug in the camera
Push the supply's 2.1 mm plug into the camera's power connector or a 2.1 mm extension lead.
03
Switch on
Plug the supply into the power point and switch on.
04
Check day and night
Check the camera runs by day and at night. Restarts at night mean it needs a bigger supply.

Pair it with
More power, more cameras
Bigger supply
Camera needs more than 0.5 A?
Our SR-PSU-12V1A 12V 1A supply has the same 2.1 mm centre-positive plug and twice the current.
Two cameras
12V 2A plus a splitter
For two to four cameras, use the SR-PSU-12v2A 12V 2A supply with the SR-DCSP-1F2M or SR-DCSP-1F4M splitter.
Bare wires
Wiring into cable?
The IFT-DCF-S socket with screw terminals takes this supply's plug onto bare power wire, no soldering.
Where it is used
Where a 12V 500mA supply fits.
Single CCTV camera
One 12V camera that draws 0.5 A or less, day and night.
CCTV microphones
Audio pick-ups that run on 12V beside a camera or recorder.
Replacing a lost adaptor
A like-for-like swap for a 12V 500mA adaptor with a 2.1 mm centre-positive plug.
Small 12V devices
Sensors, LED lights and other 12V gear on a 2.1 mm plug, drawing 0.5 A or less.
Bench testing
Power a camera on the bench while you set it up before it goes on the wall.

| Output | 12V DC, 0.5 A | 12V DC, 1 A |
| Input | 100–240V AC, 50/60Hz | 100–240V AC, 50/60Hz |
| DC plug | 2.1 mm, centre positive | 2.1 mm, centre positive |
| Efficiency | MEPS Level IV | MEPS Level IV |
| Best for | One small camera or 12V device | One camera with strong infrared, or two small cameras on a splitter |
Same plug and polarity. The current is the difference: add up what your cameras draw and pick the supply rated above it.
Common questions
Will it power my Swann camera?
Yes, if the camera runs on 12V DC, takes a 2.1 mm centre-positive plug and draws 0.5 A or less. This is a generic supply, not made by Swann. Check the camera's label or send us the model.
How much current does it give?
Up to 500 mA (0.5 A) at 12V DC.
Can it run two cameras?
Only if both together draw 0.5 A or less, for example two at 0.25 A each on a 2-way splitter. Cameras with infrared draw more at night, so check the labels.
Is the plug centre positive?
Yes. The 2.1 mm plug is centre positive: the inside contact is +12V and the outer sleeve is negative.
What mains input does it take?
100 to 240V AC, 50/60Hz, 0.35 A max, so it runs on Australian mains.
Is it approved for Australia?
Yes. It is an Australian approved supply with Australian pins that plug straight into a power point.
How long is the lead?
The 12V DC lead is about 1.8 m.
Can it power a DVR or NVR?
No. Recorders need much more current than 0.5 A. Check the label on your recorder's own adaptor.
What does MEPS Level IV mean?
It is the energy efficiency level the supply meets under Australia's Minimum Energy Performance Standards for external power supplies.
How do I check it with a multimeter?
Set the meter to DC volts, plug the supply in, then put the red probe inside the plug and the black probe on the outer sleeve. It should read about +12V.
Can I use it outdoors?
No outdoor rating is given. Plug it in indoors or inside a weatherproof enclosure, and keep it dry.
How fast can I get it?
Choose Express Post at checkout for priority handling. Orders are tracked and dispatched the same business day when placed before the cutoff.

Installation and safety
Mains powered. It plugs into a standard Australian power point. Do not open the case. A new power point needs a licensed electrician.
Do not overload it. Keep the total draw at 0.5 A or less. An overloaded supply runs hot and the camera drops out.
Match the voltage and polarity. Only connect equipment that takes 12V DC on a 2.1 mm centre-positive plug. The wrong voltage or polarity can damage it.
Keep it dry. No outdoor rating is given. Use it indoors or inside a weatherproof enclosure.
Do not modify the lead. To wire into bare cable, use a screw-terminal socket on the plug rather than cutting the lead.
What it does not do. It is not a battery charger, it cannot run a recorder, and it does not power PoE cameras.
