What Power Supply Is Required For A Motorised External Blind?

Our electric external blinds draw approximately 1.1amps, although at startup (activation of motor) this draw can double to circa 2.2amps. The tubular motor, which is built inside the external blind contained in the rollertube to either the left or right-hand side, has a sealed standard 3 core, (live, neutral, earth) power cable, exiting it, which can be up to 10m in length depending on order specification.

The power cable is simply fitted with a 3 or 5amp fused rated 3 pin plug and plugged into a standard socket or wired into a standard fuse spur again fitted with a 3 or 5amp fuse.

If there are multiple external blinds on the same project, the power cables for these can all be wired together (up to maximum 4 blinds) into a junction box, with a single standard 3 core (live, neutral, earth) power cable exiting, fitted with either a 13amp fused rated 3 pin plug and plugged into a standard socket or wired into a 13mp switched fuse spur.

A motor power cable is never cut shorter than 1m, as the first 1m of the power cable contains the antenna for the blind motor and cutting this reduces the operating range which is typically 200m in open space or 20m through two reinforced concrete walls but can vary due to local electronic devices such as phone masts.
