MOSO Power Unit 12V 1.5A

The MOSO Power Unit 12V 1.5A (SKU MOSO-PSU-12V-1.5A-EU) converts mains electricity into a 12V DC supply. DC means direct current, the steady kind of power that low-voltage equipment runs on.

What the figures mean for you

• 12V DC: it suits equipment that asks for a 12V DC supply. A device rated for a different voltage is not a match.
• 1.5A: this is the current the unit supplies. Multiply it by 12V and you get 18W, the ceiling for whatever is connected.
• EU plug: the mains end is EU type, so check it suits the socket you plan to use.
• Connector: size and polarity must match your equipment. Polarity is the way round the positive and negative connections run.

Checking it is enough

Find the rating label on the device you want to power. Confirm it states 12V DC, then compare its connector with this unit's. If you are powering more than one item, add up their wattages. The total has to stay within 18W.

If the load is a night-vision camera

Infrared (IR) LEDs light the scene for the camera in the dark, and they draw more power at night. An under-rated supply, or a long or poor-quality cable, can cause voltage drop. You see it as flicker or a black image after dark, even when the daytime picture is fine. Verify both the adapter's rating and the length of the cable run.
