Konstsmide 12v TRANSFORMER 48w Low Voltage Outdoor Transformer

12v Transformer (transforms mains 230v to safe 12v) - 48w maximum power output.

Transformer comes pre-fitted with a UK 3-pin plug and includes 4 outputs of 1m extension cable. Fitted with a timer and dusk to dawn sensor

Just plug it in, switch on and the UK mains and 230v AC power is reduced to safe 12v AC power.

If the total power consumption of your garden lights is very near to, or exceeds, the power output rating then you should split your cabling runs and use more than one transformer.

The transformer can be fitted safely outdoors but if the 3-pin plug is to be sited outdoors then it should be fitted in a waterproof electrical socket housing similar to the one shown below:

An RCD is a residual-current device, or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing 230V electric shock.
