A power supply is an electrical device that takes an incoming electrical current and converts it into the correct voltage, current, and frequency required for industrial equipment. Also known as electric power converters, DIN Rail power supplies are reliable, efficient, and compact.

DIN-Rail power supplies are a special type of power supply that is mounted onto DIN Rail. These electrical devices provide a convenient and space-saving solution for providing power to appliances used in process control, factory automation, power distribution, and other industrial applications.

RS offer a comprehensive range of high-performance DIN Rail power supplies from leading brands including Siemens, Omron, Mean Well, Phoenix Contact, TDK-Lambda, Weidmuller, XP Power, and of course RS PRO.

What is DIN Rail Mounting?

A DIN rail is a metal rail used to mount electrical devices in control cabinets, enclosures racks, and panels. DIN Rail is manufactured to conform to a specific set of standards outlined by the Deutsch Institute von Normen (DIN). Due to the uniform profile, it ensures electronic devices such as circuit breakers, relays, and power supplies can be sourced from several different manufacturers and suppliers, safe in the knowledge all products can be mounted on the same rail.
