DC-DC Converter Ensures Stable, Electrically Isolated Supply
Targeting 24-V dc power-supply applications, Weidmuller’s new dc-dc converter avoids critical earth loops and thus can generate a stable, low-distortion output voltage from an unregulated or distorted input voltage. The electrically isolated device, which is the latest entry into the company’s PRO-M Power Supplies line, features high resistance to shock and vibration and 91% efficiency. Its 60-mm width and ability to be mounted side-by-side without clearance requirements saves cabinet space, and a metal clip-on foot increases stability on the DIN rail. A status signal enables remote monitoring—an alarm output monitors the status of the 24-V output voltage, and an LED indicates DC OK status for the output voltage. Operating temperature ranges from −25 to +70°C. Class III protection (internal fuse on the input and output side, short-circuit and overload protection, power boost at 24 V dc of 12 A for one minute) suits the device for earth-free power systems (e.g., battery-backup systems in marine technology).
