Intellinet 508728 Industrial DIN-Rail Mount Power Supply Unit - 120 W



DIN-Rail Mountable 120 W PSU for Industrial Environments - power up with reliability and efficiency in a small form factor:

The DIN rail power supply plays an integral part in industrial applications such as automotive, mechanical engineering, logistics and even some ambitious home applications in outdoor lighting controls, amateur radio and many more.

A PSU with USPs:

To meet high application demands, this PSU from Intellinet Network Solutions comes with high-energy efficiency, maximum safety, a space-saving design, wide temperature tolerance and a long lifetime. Its DIN rail mounting (also known as top-hat rail) lets it fit right at home in industrial applications, where the DIN rail is a fixed component of many cabinets, machines and distribution boxes.

Creates less heat to save you money:

The metal housing of this PSU enhances the unit’s power dissipation to work even in extreme temperature conditions of -20 - 70°C (-4 - 158°F). The unit's high-quality components help contribute to high efficiency, which leads to lower no-load losses and therefore less heat generation in the entire system. Its smart construction saves you on outright energy costs during operation and helps you save additional money in cooling the entire application.

More power in less space:

The PSU's ability to generate less heat in the power supply means it also can be made more compact. With a width of only 40 mm (1.57 in.), the slim shape of this PSU saves a lot of valuable space. It can easily be installed in confined systems or small on-site control boxes. This PSU is convection-cooled, which means that that the electronics are cooled only by natural airflow. Since fans aren't required, there are fewer moving mechanical elements, which decreases the probability of failure and device maintenance requirements.

Full-scale protection and safety:

To fully protect your mission-critical equipment, this DIN-rail mount power supply features over-voltage, over-temperature and overload protection with constant current limiting. TÜV, UL and EMC compliance guarantee safe use in industrial applications.
