These Class 2 isolation devices do not need ground connections. This simplifies installation and reduces costs. All of the power supplies feature short-circuit, overload, and overtemperature protection. The UL-508-listed power supplies mount directly onto the DIN rail and have their functions, descriptions, and wiring information displayed on their front panels. In addition, they have a universal rated input voltage of 120 to 230 Vac, which makes them suitable for worldwide use.
