All of the converters have input-to-output isolation and are rated at 120W with a temperature range from –25°C to 60°C. The units can deliver an additional 20 percent power reserve and are designed to save space on the DIN rail with a width of only 32mm. Other features include a built-in soft start, electronic inrush current limitation, input polarity protection and a comprehensive approvals package. The converter has two built-in relay contacts. The “Input-Low” contact can be used to detect a battery that is discharged and the “DC-OK” contact makes it possible to build redundant systems.PULS Power Supplieswww.puls-power.com/us630.587.9780
