DIN Rail Power Supplies

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 and can operate in constant current mode and constant voltage switch mode. 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 Malaysia offers a comprehensive range of high-performance DIN Rail power supplies from leading brands and suppliers. These include Siemens, Mean Well, Phoenix Contact, TDK-Lambda, XP Power, and, of course, RS PRO.

What is DIN rail mounting?

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 Institut von Normen (DIN). The uniform profile ensures that electronic devices such as circuit breakers, relays, and lab power supplies can be sourced from several different manufacturers and suppliers, safe in the knowledge all products can be mounted on the same rail.

What are the advantages of a DIN Rail power supply?

As we mentioned, DIN Rail power supplies are very versatile and adjustable, and come with various specifications and functions to suit your every need. RS Malaysia's power supply units offer the following features and benefits:

• Universal AC single-phase input voltage ranging from 90 to 264 V ac;
• Wide selection of DC output voltages ranging from 5 V dc to 48 V dc;
• Wide selection of power ratings ranging from 2.5 Watt to 1.5 kW;
• Easy connection, installation, and maintenance;
• Robust and reliable;
• Compact and lightweight.

Where would a DIN Rail power supply be used?

These DIN Rail power supply units (PSUs) can be used in a multitude of applications across many industries. Some of the most common are:

• Sensors
• PLC's
• Solenoids and actuators
• Energy-efficient relays
• Motors
• Transmitters/receivers
• Security and alarms

Do linear power supplies make a difference?

While linear power supplies regulate output voltage by converting excess energy into heat, switch-mode models, such as DIN rail power supplies, adjust input voltage rapidly to achieve the desired output voltage. In doing so, DIN rail power supplies minimise energy lost as heat and increase energy efficiency of the process.

How do I choose a linear power supply?

Nonetheless, linear power supplies still offer distinct advantages. For instance, they are ideal for low-power applications where minimal noise, high precision, and straightforward design are critical, such as audio systems, medical device measurements, and test instruments. Meanwhile, DIN rail power supplies are preferred for high-power applications requiring efficiency, compactness, and cost-effectiveness. These include computers, consumer electronics, and telecommunications equipment.
