Demands on the power supply market are steadily increasing, so maximum efficiency and constant performance even at high temperatures are essential. Diagnostic and communication facilities are also increasingly in demand as the components are integrated into higher-level networks and become part of Industry 4.0 applications. At the same time, ‘classic’ applications still exist in which a power supply solution that operates reliably, flexibly and economically is needed.

To meet all these demands, Murrelektronik has introduced the Eco-Rail-2 power supply units which, it explains, offers manufacturers of machinery and control cabinets the possibility to supply power to their consumers flexibly and economically.

Five devices are available in the series, with current ratings from 1.3 to 20A, while the output voltage of the devices can be set from 23 to 28V. Connecting two power supply units in series allows the output voltage to be increased to 48V.

The products have an operating temperature range of between 0 and 55°C, and can be easily mounted on the DIN rail without any tools. The screw terminals are attached to the front of the unit to facilitate quick and easy cable connection. Furthermore, the ‘hold-up time’ of the Eco-Rail-2 series switch-mode power supplies is up to 130ms, helping to bridge voltage drops at the input side.
