Need to step down UK mains voltage by half? This transformer from Siemens will do just that, taking a 230V AC primary voltage and bringing it down to a smooth 115V AC. You can use it to protect against short circuits, overloads and electric shocks, giving you the peace of mind that the people and equipment in your workplace are safe. The unit mounts onto a DIN rail, for fuss-free integration into a compact and organised system. Twin outputs mean you can power two loads from one transformer, saving you time, effort and space in the cabinet. You'll find this device commonly used in medical settings and HVAC systems.

• Screw terminals help you make quick and secure connections

A DIN rail is a metal rail built to standard dimensions. You can use it to mount many different terminal blocks, circuit breakers and industrial control equipment inside an equipment rack. They're available in slotted and unslotted variants.
